GUYS AND ST THOMAS’
Guy’s and St Thomas Hospitals in central London are both benefitting from energy savings delivered by Autoflame’s turnkey boiler house projects. Autoflame equipment was specified, and they successfully tendered to deliver the energy efficient upgrade for both Guys and St Thomas’s hospitals. Guys’s Hospital was originally upgraded in 2006 with Autoflame Micro Modulation Controls, the hospital monitored a step change reduction in energy usage and this lead the Trust to invite Autoflame to make recommendations to carry out an energy saving project for the steam boilers at St Thomas Hospital.
Autoflame recommended that the hospital consider replacing the existing Saacke Rotary Cup burners using DDC controls to a Limpsfield Burners with Autoflame Mk7. Autoflame worked closely with the hospital and put together a report detailing the existing combustion analysis and calculated what gas savings could be achieved by upgrading the burners and controls to Limpsfield with Autoflame.
A performance guarantee was offered on the combustion performance of the new equipment; O2 levels throughout the firing range were guaranteed to be no greater than 3%. With optimum efficiency in mind the Limpsfield Burner has been engineered to be a low excess air burner. Autoflame Combustion controls ensure repeatability of this optimum performance. Autoflame’s engineering team worked around the needs of the hospital ensuring that 3 out of the 4 boilers were online throughout the project, to meet steam demand.
The hospital monitored an impressive gas saving and was so pleased with the results, the reliability of the equipment and improved functionally that they invited Autoflame to look at a similar burner replacement project at Guys Hospital which is scheduled to be completed in 2017.
