Heating unit for combustion of oil and gases for use in domestic heating

摘要

Oil and gases are combusted in an internal combustion engine forming a heating unit and a small part of the mechanical energy generated is used to drive auxiliary machines, such as oil pump, water pump, electric generator etc. Preferably, the electrical power of a generator is used to drive the auxiliary machines. A gas pump is incorporated in addition to the scavenging pump required for operating the internal combustion engine and acts as heat pump, such that the effective heat energy is more than the primary energy supply of the oil or gas.
