Small combustion plant with lambda probe and thermogenerator

Abstract

Small combustion plant (10) with a combustion chamber (11) and an exhaust pipe (12), wherein a lambda probe (13) for determining lambda or an oxygen partial pressure in the exhaust gas is arranged in the exhaust pipe (12), wherein a thermogenerator (14), in particular a Peltier element, is arranged on the wall of the exhaust pipe (13) or the combustion chamber (11) to convert heat generated during the operation of the small combustion plant (10) into electrical energy, wherein the thermogenerator (14) is electrically connected to the lambda probe (13) or to an electrical control unit of the lambda probe (13) to supply the lambda probe (13) or the electrical control unit of the lambda probe (13) with electrical energy.
