Natural Gas CHP Module Overview
Wolf BHKW units have the same essential structure over the full range of powers out puts: a frame constructed of steel sections forms the heat exchanging unit with the connections for the heating supply and return lines, exhaust and fuel.
The unit comprises a plate heat exchanger that takes heat from the engine's cooling water, a shell and tube heat exchanger that exchanges heat with the exhaust, and a flue gas cleaning unit.
A combined heat and power unit can achieve an efficiency of about 90%, meaning that 90% of the primary energy is converted into electricity and heat. If the radiated heat can be included, the efficiency can even reach about 95%. The efficiency of a conventional power station is between 30 and 40%. The advantages are clear.
*Efficiency figures are due to variations in measurements, fluctuating conditions and variations in the fuel quality of a tolerance of up to 5%.

Natural gas, sewage gas, LPG and biogas are likely sources of primary energy. The combustion engine, a gas-burning four stroke engine, drives a generator. The generator converts part of the energy used into electrical power. The electricity is used in the consumer network or is given directly to the power supply company.
