Used Combined Heat And Power Generators

CHP generators have been a cornerstone of the Gas Engine Exchange stocklist for years. Due to their high efficiency, combined heat and power generators are a popular choice for many projects that require electrical and thermal energy, including office buildings, hotels, hospitals and factories. Each year, Gas Engine Exchange has a wide range of good condition used combined heat and power units for sale. These generally range in capacity from small scale CHPs of 50kW to larger generators of around 2.5MW and above.

If you are interested in combined heat and power generators to maximise your efficiency, contact Gas Engine Exchange.

Used CHP generators

Combined Heat and Power (CHP) is a technology that produces both electricity and thermal energy from one fuel source. Gas Engine Exchange can source used CHP generators that can run on natural gas and biogas. All the leading generator brands including: Jenbacher, Caterpillar, MWM, MTU, MAN, Scania and more, have CHP generators. We aim to have at least 30 CHP generators on stock at any one time. If you have a specific need please contact us.

Used Cogeneration generator sets

Combined Heat and Power is also known as cogeneration. One of the main advantages of a cogeneration generator set is that it is very efficient. This is because the waste thermal energy produced during electricity generation can be recovered and used in the form of heating, steam, cooling, or to produce hot or cold water. The thermal energy can be recaptured using specialist CHP technologies including: exhaust gas heat exchangers, jacket water heat exchangers and engine oil heat exchangers.

How efficient is a CHP?

The extra efficiencies generated due to minimising heat loss mean CHP systems can be the most economical and environmentally-friendly way to power a project. According to the UK government, cogeneration “can reduce carbon emissions by up to 30% compared to the separate means of conventional generation via a boiler and power station”. Additionally, Jenbacher says its generators can increase overall power plant efficiency up to 90% and that fuel input can be reduced by up to 30%, when compared to producing electrical and thermal energy separately. Due to this, in some countries subsidies are offered to those using efficient CHP generators.

What is the difference between Cogeneration and Trigeneration?

Cogeneration is combined heat and power. Trigeneration is known as combined cooling, heat and power (CCHP). This when a single reciprocating engine uses one fuel source to produce electricity and reuse the excess thermal heat for both heat and cooling.
