Combustion apparatus i.e. central heating boiler for use in central heating system, has pipeline for supplying combustible air-fuel mixture to combustion chamber, where pipeline includes channel wall formed by wall of combustion chamber

摘要

The apparatus has a combustion chamber with a burner for burning a combustible air-fuel mixture, and a pipeline (1) for supplying the combustible air-fuel mixture to the combustion chamber. The pipeline includes a channel wall (2) formed by a wall of the combustion chamber, where the channel wall includes ribs (7a, 7b) stretching in a flow direction of the pipeline, and the ribs are made of a heat conductive material.
