Abstract: A heating apparatus, which is intended, particularly, for incorporation into a vehicle liquid heat exchange circuit has a control device, to which a liquid flow measuring device is connected. If the liquid flow measuring device detects that a predetermined liquid flow has been reached or exceeded, the control device of the heating apparatus can be put into operation as a function of other control variables. If, on the other hand, this predetermined liquid flow is not reached or exceeded, the control device, by its connection to the liquid flow measuring device, prevents turning on of the heating apparatus. As a result, the heating apparatus is turned on and delivers heat only if a heating requirement exists.

Abstract: In an exhaust gas pipe of a diesel engine, a particle separator serving for reduction of the particle emission of the diesel engine by exhaust gas aftertreatment, a burner by which the particle separator can be regenerated by means of hot fuel gases delivered by the burner unit, the burner unit is so placed that, even in the case of leaks occurring at a flap valve for shutting off of the fuel gas line, no impairment of the operation of the burner is to be feared. For this purpose, upstream from the burner, a blower may be installed, which constantly provides air to the burner unit and the space of the fuel gas line between the flap valve and the burner unit, the air being discharged from the space into the environment by a vent pipe. In this way, exhaust gases, which leak past the closed flap valve into the fuel gas line, do not reach the burner and are discharged by the vent pipe into the enviroment.
