Burdened with cumbersome maintenance, expensive spare parts and very high energy costs, a wastewater treatment plant has replaced its multi-phase eccentric screw pumps with new Rotary Lobe pumps, made by Börger.

Installed for a chamber filter press, the space-saving Börger pumps have been supplied as a twin-pack unit; two identical Rotary Lobe Pumps, which are operated in series. Each Börger rotary lobe pump has its own frequency converter that allows speeds to be individually regulated.

When feeding the chamber filter press, operators at the wastewater treatment plant now have a choice between two phases - the pre-fill phase and the pressurized phase. During the pre-fill phase, large quantities of sludge are pumped at high speed into the chamber filter press to fill up its chamber.

As the solids in the sludge gather in front of the filter screens, the increasing filling level of the chamber increases the counter pressure in the chamber filter press. Using the frequency converter, the speed of the Börger pumps is then reduced accordingly.

In addition to improving the output and efficiency of the application, the new Rotary Lobe pumps have drastically reduced energy costs, and are also far easier to service with their easy access, Maintenance-In-Place design.

By releasing the new MGF X Line range of oil-free compressors into the UK market, FPS Air Compressors is providing dental labs running CAD/CAM-driven milling machines and 3D printers with a proven way to utilise a continuous and highly reliable source of clean, dry compressed air without risk of contamination.

Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) systems are finding growing use in the creation of dental restorations such as crowns, bridges and veneers. The new X Line can supply clean and dry compressed air continuously and reliably to CAD/CAM-driven milling processes, ensuring the precise, reliable and high-integrity production of dental prosthetics.

A further benefit of using innovative MGF X Line compressor technology at dental labs is increased air capacity and, subsequently, lower energy bills. This advantage arrives courtesy of a patented MGF system that reduces the air requirements of the membrane dryer, which in turn increases the available flow of air from the compressor by 20-25% to help optimise dental lab processes such as milling.

The X Line is also ideal for serving 3D printers, which although an additive rather than a subtractive process like milling, still need a compressor that provides continuous, high air quality and low vibration to support the precision and stability demanded by the 3D Printers industry. Notably, as 3D printing technology becomes more widespread, the importance of air quality in the printing process is gaining more and more attention in the process.

                                                                                                                                                                        Continued ……

Producing consistent air quality is a primary capability of X Line compressors, which house a 0.01 µm filtration system and a high-quality, high-efficiency membrane dryer. The provision of clean, dry, continuous air allows dental labs everywhere to take advantage of uninterrupted workflows. X Line compressors run at a maximum pressure of 10 bar, producing constant air flow at the capacity stated from a broad range of models suitable for multi applications.

Offering yet another advantage, the low vibration of the cabinet-housed X Line air compressors contributes to quiet operation. In addition to the four ‘Base’ models, a trio of ‘Silent’ versions are available providing low noise levels that do not exceed 53-56 dB(A). Furthermore, with the robust build quality, X Line compressors offer highly durable operation and a long service life, helping to minimise total cost of ownership (TCO) for dental labs.

Ultimately, the MGF X Line combines efficiency, performance and reliability with extremely quiet operation, providing genuine added value to dental labs running CAD/CAM-driven milling and 3D printing processes.

In addition, FPS extensive range of oil-free and SCROLL compressors are suitable for a myriad of applications in other sectors that demand high air quality. These include: product handling and packaging at food and beverage plants; aseptic processes and cleanrooms in pharmaceutical facilities; circuit board manufacturing and chip production in the electronics market; jet looms and air splicing at textile factories; testing and analytical instruments at research laboratories; and sampling and analysis devices in environmental monitoring processes.

Introduction

Improving fired heater performance is crucial for optimizing energy consumption, reducing emissions, and enhancing overall process performance. In large-scale process facilities, energy typically accounts for at least 50% of operating costs. An energy use reduction of 10% will often improve margins by 5% and reduce CO₂ emissions by 10%.

This article will discuss symptoms and causes of fired heater performance issues, and the solutions available to fix them and improve efficiency.

What are the Symptoms of Underperforming Fired Heaters?

Inefficient fired heaters can lead to increased energy consumption, decreased production rates, and potentially unsafe operating conditions. There are several symptoms of fired heater underperformance:

• Elevated Bridgewall Temperature
• Tube Overheating
• High Stack Temperature
• Production Bottleneck
• Excessive CO2 and NOx Emissions
• Insufficient Process Pre-heat/Steam Production
• Excessive Ammonia Slip

What are the Causes and Solutions of Underperforming Fired Heaters?

Cause 1: Fouled Convection Section Tubes

Fouling, which is the accumulation of deposits on the inner surfaces of the heater tubes in the convection section, can reduce heat transfer efficiency. Common fouling agents include carbon deposits, coke, ash, and other particulates. Fouled tubes can reduce heat transfer rates, increase fuel consumption, and decrease overall efficiency.

Solution 1: Robotic Convection Section Cleaning

To restore heat transfer efficiency, convection section tubes should be cleaned regularly. Robotic methods to remove fouling are now favoured as they offer several benefits compared to traditional manual cleaning methods, including:

Increased efficiency and speed: Robotic systems are more precise and can navigate complex geometries and hard-to-access areas with greater speed. This results in faster cleaning cycles and reduced downtime during maintenance.

Remote Operation: Robotic cleaning systems are often operated remotely, allowing technicians to control and monitor the cleaning process from a safe distance. This is particularly advantageous in situations where the convection section poses safety challenges.

Cost Saving: The initial investment in robotic cleaning services can often be higher than manual labor costs, however, the long-term benefits often outweigh this. Improved efficiency, reduced downtime, enhanced performance, and decreased maintenance needs can lead to significant cost savings over the equipment's lifespan.

Environmental Benefits: Efficient convection section cleaning helps maintain optimal heat transfer efficiency, leading to reduced energy consumption and lower CO2 and NOx emissions. This aligns with sustainability goals and environmental regulations.

Conducting a technical evaluation before cleaning the convection section is advisable. This will indicate the expected performance gains in terms of increase in capacity, % reduction in emissions, and fuel consumption benefits.

Watch: Robotic Convection Cleaning

Cause 2: Radiant Tube Scaling

Radiant tubes are designed to transfer heat from the combustion of fuel to the process fluid or material being heated. However, they are susceptible to scaling, which is the deposition of solid materials on the external surfaces of the tubes. Scaling can have several negative effects on the performance and efficiency of radiant tubes including reduced heat transfer efficiency, tube overheating, emissions increase, and higher bridgewall temperatures.

Solution 2: High Emissivity Coatings

High emissivity coatings, such as Cetek coatings, are materials that besides improving radiant heat transfer, also prevent oxidation and scale formation on the radiant tubes. These coatings are applied to the external surfaces of the tubes and significantly enhance heat transfer to the process and protect tubes from scaling. They are designed to withstand high temperatures and harsh operating conditions.

Some of the benefits of high emissivity coatings include:

Extended Tube Lifespan: By preventing oxidation and associated tube wall thinning, the life of the radiant tubes can be extended, if oxidation is the limiting factor.

Reduced Fuel Consumption: High emissivity coatings can help achieve the desired process temperatures with less energy input by improving heat transfer efficiency. This can lead to reduced fuel consumption and lower operating costs.

Watch: Catalytic Reformer Heater Process Tube Coating

Cause 3: Refractory Deterioration

Refractory deterioration can lead to hot spots on refractory material. It is an area of localized high temperature within a furnace, kiln, or other high-temperature process equipment where the refractory material is exposed to more intense heat than the surrounding areas. Hot spots can occur for various reasons and can have negative implications for the performance, efficiency, and lifespan of the refractory lining.

In these cases, the operator must decide whether to interrupt production by bringing the heater off-line to make a conventional repair or continue at reduced capacity until the next scheduled shutdown.

Solution 3: Online Heater Repairs

To avoid costly shutdowns or operating at a reduced capacity, it is possible to conduct online refractory repairs until further maintenance can take place during a planned shutdown.

Online refractory repair can be a valuable strategy to extend the lifespan of refractory linings and minimize downtime. However, it should only be performed by qualified and experienced personnel following proper safety guidelines and in accordance with industry best practices. Consulting with Hot-tek refractory experts and conducting thorough assessments are essential to ensure a successful outcome.

Conclusion

There are many causes of fired heater underperformance. It is important to identify warning signs early as even a 1-2% decrease in efficiency in fired heaters can consume an additional $1m in fuel across a 12-month period.  

To address this issue, it's crucial to conduct regular inspections, implement proper maintenance practices, monitor operating parameters, and address any issues promptly. Engaging with experienced process engineers and fired heater experts can help diagnose and resolve underperformance issues effectively.

In the context of Condition Based Maintenance (CBM) it is generally accepted that measuring the vibration of a rotating machine (motor, pump, fan etc.) will tell us something about the condition of the machine. But what exactly are we measuring and what does it tell us about the machine?

Basically, it boils down to two numbers. One is the average (RMS) value of the low frequency vibration that tells us something about how well the machine is running. The other is the average value of the high frequency vibration that tells us something about the condition of its bearings.

The low frequency vibration is the typical “hum” you hear from a rotating machine. This vibration is due to the centrifugal force resulting from any out-of-balance in the machine. Since it is virtually impossible to exactly align a machine’s centre of gravity with its centre of rotation, even a well-balanced machine will still vibrate or “hum”. But what is an acceptable level? This is where the International Standards Organisation (ISO) comes to our aid. ISO have produced a set of guidelines that define suitable levels of machine vibration in the frequency range 2Hz to 1kHz (120 RPM to 60,000 RPM). That frequency range being chosen because it covers the vast majority of machine running speeds normally encountered.

The high frequency vibration is the typical “whine” you hear from a badly worn bearing. In practice, it is there all the time but is inaudible until the bearing becomes so bad it is probably about to fail. Fortunately, a vibration analyser can detect the inaudible bearing noise well before it gets to that point. This means bearing wear can then be displayed, for example, in Bearing Damage Units (BDU) that can very roughly be thought of as a “percentage” of bearing wear.

Vibration analysers employ sensors to capture a vibration waveform from a machine and then analyse it to automatically generate the ISO reading and the bearing condition. It is largely this ability that distinguishes them from simple vibration meters. The readings below, taken from a typical VibTrend report, show vibration levels measured on a motor. The ISO readings appear in green as they are below the recommended 4.5mm/s ISO warning level for a medium size motor. However, the drive end bearing noise is displayed in red as it is above the specified 100 BDU critical alarm level. The high BDU reading was in fact due to an outer race defect on the drive end bearing.

Test Products International manufactures a complete range of low-cost, high-performance vibration analysers from the £575, one-button-to-press TPI 9070, to devices that include advanced diagnostic and machine balancing capability. The TPI 9070 features colour coded alarm levels and zoomable on-screen vibration frequency plots together with on-meter analysis for the detection of machine faults such as unbalance, misalignment, looseness and bearing wear.

The TPI 9080 from £1,100 comes complete with VibTrend PC based trending and reporting software that includes automatic report generation and email notification of alarms, implementing a full CBM solution. The TPI 9080 can store lists (routes) of machines (up to 1000), each with up to 10 measurement points, all with full vibration waveform and frequency spectrum (FFT) capture.

Routes and readings can be transferred between the TPI 9080 and the included, license free, VibTrend in a variety of different ways.  Via the included USB docking cradle, wirelessly via Bluetooth or remotely via a Bluetooth link with a smart phone or tablet running the free TPI Bridge App. This allows service personnel to receive and return routes and readings, no matter where they are in the world.
