Boilers & Burners

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.

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 Oen, 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.

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.

The collaboration between Degussa and Energyst is very varied in its nature. Within the framework of the expansion of the public utilities, linked with the construction of the new Methionine factory in Antwerp, Energyst offers support by means of temporary heating and cooling equipment.

In consultation with the central energy unit, and their German colleagues, Energyst supplied several back-up central heating boilers during the expansion work carried out within the gas supply system.

Four new courses have been added to this year

Thermal Energy International Inc., which recently acquired the Bristol based steam trap manufacturer GEM Ltd, is launching its highly acclaimed FLU-ACE technology to the UK and European market.  Greatly improving the fuel efficiency of boiler operations, FLU-ACE provides a significant return on investment, and reduces environmental emissions.

FLU-ACE effectively converts an Industrial boiler into a condensing boiler and, in so doing, effectively recovers up to 90% of the heat normally lost. This is possible because FLU-ACE

One of the challenges facing plant instrumentation engineers today is the effective and reliable monitoring of thrust bearing wear in critical pump applications.  Typically pumps of this type are in continuous use and operational downtime is normally only permitted during planned outages.  Predicting the wear and hence requirement to replace the thrust pads, is essential to fit in with this regime.

 With rotational speeds between 3000 and 7000 RPM, protection against potential pump damage is also key, as excessive thrust wear can not only damage the bearing assembly but also the impeller, resulting in the plant potentially being out of action for 6 months or more.
