Energy Management

Adrian Langford is General Manager of the Process Burner Division at Lanemark International Ltd. who have been at the forefront of process gas burner design and installation since the early 1980s. He believes there are a number of steps that could be considered and taken – either via converting existing ‘point of use’ systems or replacing centralised facilities – which can help to mitigate against the new energy cost environment in which, he says, UK manufacturing must now operate. The rapid increase in energy prices is exercising minds both in the home and in the factory. On the domestic front the consistent suggestion from the media is to ‘shop around’ to ensure that the price paid for each kW of gas and electricity consumed is reduced to the minimum possible. Sensible advice, but while this pursuit of the best energy deal can lead to reductions in the amount of money that has to be spent, in industry it is only part of the story. Here, the real key is to reduce the total number of kWh that are used in manufacturing applications by critically appraising existing process heating methods in order to maximise operating efficiencies while, at the same time, identifying the optimum energy source for each process.

Unified worldwide efficiency classifications for low voltage three-phase asynchronous motors are being introduced as part of a concerted international effort to increase energy efficiency and, unsurprisingly, HPC KAESER screw compressors are already being equipped with premium efficiency motors in accordance with these newest standards.

Defining Energy Efficient Motors
The efficiency of an electric motor is de-fined as the ratio of usable mechanical power to electric input power. In Europe, low-voltage three-phase motors were previously divided into EFF3, EFF2 and EFF1 efficiency classifications. Differences among various national systems with regard to scope and classification prompted the International Electrotechnical Commission (IEC) to develop a unified standard. In parallel, the IEC’s improved methods for determining efficiency were revised and standardised. The new IEC 60034-30 standard de-fines and harmonises IE1, IE2 und IE3 efficiency classifications for low-voltage three-phase motors worldwide.

Former European Motor Efficiency Classifications and Previous Measuring Methods
The voluntary agreement between the European Committee of Manufacturers of Electrical Machines and Power Systems (CEMEP) and the European Commission, in effect since 1998, defined three efficiency classifications:

• EFF3 = Standard efficiency motors
• EFF2 = Improved efficiency motors
• EFF1 = High efficiency motors

The minimum values for the various classifications were based on efficiency measurements in accordance with EN60034-2:1996.
Titan Enterprises supplies innovative flow measurement solutions into a broad range of sectors, including medical, industrial, food & drink, laboratory and pharmaceutical. Its latest innovation, the Atrato flowmeter range, is set to challenge conventional flowmeter thinking the world over.
 
The Ultraflo is a transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!

Programming the unit is carried out by selecting the options displayed in the main menu and by following the simple instructions in any of the user selectable languages. Signal strength, time and date, as well as flow information are all continuously displayed, keeping the user fully aware of the measurement process.

“Gelpack Industrial Ltd has made an annual saving of over 45% on energy used to generate compressed air using a retro-fit Variable Speed Drive package from EnergAir”

A compressed air audit conducted at Gelpack Industrial Ltd revealed that 40.18% of the input energy used to power the compressors was not productive, and that system pressure was higher than required. This was due to the inefficient operation of two fixed speed, 75kW, Worthington Rollair compressors, which were used on a rotating basis to provide compressed air to the factory. The audit highlighted the potential savings that could be made by retro-fitting a variable speed drive (VSD) to reduce offload running and match air generation more closely to system demand.

She was ready earlier this year: the Seven Atlantic, an ultra modern support vessel for divers in the North Sea. Responsible for the electrical wiring is Croon-Bakker Sliedrecht, who during the test phase could rely on the services of Energyst CAT ® Rental Power.

The recent delivery of the Seven Atlantic Subsea 7 to its owner meant the next step in a truly epic project for IHC Merwede Shipyard in Hardinxveld-Giessendam. In a relatively short time the company has produced two so-called pipe laying vessels – the Seven Oceans and the Seven Seas - and has completed project number three with the transfer of the Seven Atlantic. They are currently already working on the fourth ship, which as of yet remains nameless. Starting this year, the ships will perform their duties in the deep oil fields in the North Sea.
