Combined Heat and Power systems for business
What is Combined Heat and Power?
Combined Heat and Power (CHP) is the generation of usable heat and power - usually electricity - simultaneously in a single process. It utilises the heat which would otherwise be wasted when generating electrical or mechanical power. CHP is technologically proven and reliable and plays a key role in helping to reduce the UK's carbon emissions.
It is a highly flexible way of providing the energy requirements for businesses, as it can be used on any scale - from a micro-CHP unit of several kilowatts suitable for small businesses, up to a medium-sized power station servicing a whole industrial complex.
It can also run on a range of fuels, including gas, waste and biomass.
How Combined Heat and Power works
CHP systems supply heat where additional fuel would ordinarily need to be burned to get the same output - for example, by a conventional boiler.
A gas or steam turbine or an engine is used to drive an alternator, with the electricity produced either used on-site or exported to the grid.
The heat produced can then be used for a number of applications, including steam for industrial processes and hot water for space heating and for cooling via a technology known as 'absorption chillers'.
