The Role of Fireside Corrosion on Boiler Tube Failures, Part I

COAL POWER magazine :: Operations & Maintenance >> 
One of the primary challenges of reliably burning coal is managing the corrosion experienced by the furnace heat transfer surfaces. Fireside corrosion remains a leading cause of failure in superheater and reheater tubes. Three case studies examine the different failure modes experienced by tubes located throughout the furnace....

Power 101: Flue Gas Heat Recovery in Power Plants, Part I

COAL POWER magazine :: Operations & Maintenance >> 
Every power engineer must have a firm grasp of the rudiments of how fuel is processed to produce electricity in a power generation facility. With this article, we begin a series of Power 101 tutorials that present these fundamentals in a clear and concise way. First up are the essentials of recovering heat from flue gas....


A major addition is being made to the range of process gas burner systems available from industry leader Lanemark International Ltd. that is set to enhance the choice of application opportunities for its customers.  The company has announced an agency agreement with American manufacturer, Midco International Inc – covering the UK and other key international markets – which complements Lanemark’s highly successful TX tank heating and FD air heating product ranges.

Midco burners are widely known for the benefits they offer to a number of industries, most notably where make up or replacement air requirements need to be met – an example being paint spraybooth air replenishment.  High turn-down and controllability are key features as are low emission levels, flame stability and a modular design.  This latter characteristic allows any number of individual six-inch sections to be connected to meet precise application needs in terms of dimensions and heat requirement.  This versatility is further enhanced with the ability to use either natural or propane gas on a standard burner head.


The latest addition to its FD oven burner range – which is designed to maximise performance and energy efficiency – is being introduced by process gas burner specialist, Lanemark International Ltd. The FD-C (GA) packaged burner provides flexible, high turn-down control of both gas and air and utilises the latest ‘air pressure lead’ (APL) monobloc gas valve technology. 

Purchasing the right boiler for the job.

Twin Industries International (TII), with over 30 years experience in the Boiler Industry, knows the importance of purchasing the right boiler for the job and are leading Brokers, not only for new industrial boilers but also for the purchase and sale of reconditioned boiler plant and allied equipment, and the hire of boilers.
Being completely independent and therefore able to provide totally unbiased information on all Industrial Boilers, whether Steam, Hot Water, Thermal Fluid or CHP Units, TII does its utmost to ensure potential customers end up with the very best option for their business.

Wellman Robey “Combination” Boilers find favour in C.H.P

Wellman Robey “Combination” Boilers have become an integral part of two Combined Heat and Power installations for the N.H.S Foundation Trust.
The principle of the “Combination” Boiler is to take the  exhaust gases from the C.H.P electricity generator engine and use the heat from it to raise steam or hot water. A completely independent section within the boiler (with it’s own furnace and oil or gas fired burner) guarantees that the unit will be able to provide its required output at all times regardless of the supply of waste gases available by firing the boiler in the conventional way as well as (or instead of) using the waste heat recovery section.

The two N.H.S Trust Foundations that have recently taken delivery of the Wellman Robey Combination Boilers are Countess of Chester and Aintree University (Liverpool) hospitals.

Countess of Chester has 580 beds on a single site and provides a range of medical services for over 400,000 patients a year for Western Cheshire, the Wirral and North Wales. The Robey- Loos boiler supplied is a UL-S IE Composite Boiler designed for an output of 3945kg/hr at 5barG that will provide steam and hot-water for the total requirement of the hospital complex.

Energyst Oil & Gas Depot Egersund, Norway

At the beginning of September 2008 we were approached by two companies regarding the rental of an O&G unit for a small platform in the North Sea called Varg A. The generator was to run the Fire Pump onboard for any emergency situations, so it is basically a standby unit. We offered a budget rate for renting one of our new Oil & Gas units.

After several discussions and clarifications Teekay Norway took over the project at the beginning of 2009, and the ball really started rolling. We not only had to place our Oil & Gas unit on the platform, it also needed some modifications. Together with our Technical Manager, Kjell Olsen Øen, Teekay decided that they needed some very special arrangements onboard the platform. This meant that we had to rebuild certain parts of the unit, and also install an extra long piping construction for the air intake and also for removal of the exhaust gases. See pictures. The container also needed overpressure, because of the danger of gas.

Working under high voltage

Even on a rough sea, a crane has to be able to lower loads of up to 120 tons into the water, accurate to the tenth of a metre

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.
