Exhaust System

The primary function of the exhaust system is to carry the products of combustion away from the engine safely. As engines are often located in basements, and exhaust outlets are typically at roof level, careful consideration must be given to exhaust duct routing and insulation to contain heat, vibration and noise. Catalytic converters may be included in the exhaust system, either separately or combined with silencers. Care must be taken to ensure that exhaust gases are not recirculated into the building or engine intake systems. Guidance on the avoidance of recirculation may be found in the CIBSE Technical Memorandum on Minimising Pollution at Air Intakes.

Ventilation air from the engine enclosure must be exhausted. Whether existing plant room systems are used or an independent system is installed will depend on the volume flow rate required for engine ventilation and on permitted temperatures in surrounding areas.

The UK heat map has been developed as a tool aimed at assisting power station developers consider the opportunities for combined heat and power (CHP) as required under planning policy. However it can also be used by both small and large organisations to help identify the locations where CHP, renewable heat plants and district heating would have the greatest technical and economic potential, and therefore the largest positive environmental impact.
