What is a CHP?
Combined heat and power (CHP) systems are a cross between an electric generator and a boiler. They supply both electricity and heat at the same time.
What do CHPs do?
CHP systems provide both heat and electrical power. They can replace a conventional boiler, and also generate electricity to cover a portion of your requirement. Generating both heat and power from the same fuel is much more efficient than generating them individually.
How do cogeneration systems work?
An engine that burns fuel to generate electricity generates a lot of heat e.g. a power stations’ wasted heat can be seen in the clouds of water vapour from the cooling towers. This heat is wasted energy. CHP systems capture this heat so it can be used for something useful. This increases the amount of energy you can get from burning fuel: as well as running an engine, it also collects heat that would otherwise have been wasted. Only accredited micro-CHP units are eligible for the Feed-in Tariff Scheme.
As an energy generation process, CHP is fuel neutral. This means that a cogeneration process can be applied to both renewable and fossil fuels. The specific technologies employed, and the efficiencies they achieve will vary, but in every situation CHP offers the capability to make more efficient and effective use of valuable primary energy resources.
A CHP will start working in response to a demand in heat. When it runs, it also supplies an amount of electricity to supplement the electricity supply. A CHP will save money on electricity bills, but not replace your electricity supply. A domestic property has a long enough period of low demand for electricity supply. A CHP will save money on electricity bills, but not replace your electricity supply. A domestic property has a long period of low demand for electricity with regular short periods of high demand. A CHP large enough to supply these periods of high demand would be too large.
CHP is a viable choice for many companies and is an excellent option when looking for an affordable way to reduce your carbon footprint. Whether you’re in the process of building a new set of offices or warehouse, or if you are replacing ageing boiler plants, TED can help you.
