Combustion chamber assembly for evaporator burner in vehicle heating device, has combustion air fan circulating combustion air to combustion air inflow arrangement of retaining lug on melt flow path

摘要

The assembly has a combustion chamber housing (14) with a base wall region (20) and a circumferential wall region (18). An ignition member retaining lug (26) is provided in the circumferential wall region and opened to a combustion chamber (16) formed in the housing. A combustion air inflow arrangement (32) is provided at the base wall region for inflow of combustion air into the combustion chamber. A combustion air fan (42) circulates combustion air to the combustion air inflow arrangement of the retaining lug on a melt flow path.
