Rotherham Hospital's site provides a range of hospital based Medical, Surgical, Paediatric and Obstetric & Gynaecological services and services 500 inpatient beds. It prides itself in being an innovative, high performing organisation which continues to develop and grow at pace.
Rotherham Hospital required a generator to provide prime power to the hospital. With sustainable waste and energy solutions being of importance to the trust, a combined heat and power solution was specified where heat produced as a by-product can be fed back into the hospital’s existing heating system.
Finning specified a containerised Caterpillar® G3516B gas generator set with an electrical output of 1.1 MWe and a thermal output from recovery of heat in the jacket water and exhaust of 1.5 MWth. The CHP system, which is connected to the existing heating system, offers a total heat recovery of 1545kW and is the prime source of heating for the hospital with the existing site boilers used to provide extra resource where required.
The CHP solution uses heat exchangers to harvest heat from the engine water jacket, oil coole heat from the engine water jacket, oil cooler, after cooler and exhaust gases to produce hot water. Finning connected this to the existing low temperature hot water system.
