Building furnace has combustion air feed units that supply combustion air with fuel vapor from evaporator burner arrangement, and ignition unit provided to ignite fuel vapor-combustion air mixture

摘要

The furnace (10) has combustion chamber (14) provided with evaporator burner arrangement (28). The evaporator burner arrangement has a porous evaporator medium (40) for storing liquid fuel and delivering fuel vapor into an open combustion chamber (34). Combustion air feed units (50,52) supply combustion air with fuel vapor. An ignition unit (54) ignites the fuel vapor-combustion air mixture.
