Combustion air supply system for parallel burners - supplies air uniformly by natural draught to burners in sealed housing

摘要

The combustion air supply system is used for several parallel operated burners of a heating plant. The burners use natural draught for ensuring air supply. All burners (9, 10) are enclosed by a common airtight housing (2). The housing central part has single air supply opening (5) which can be closed. The closing condition can be adjusted and profiled inner wall of the housing (2) which encloses the burners, ensures uniform distribution of air to the burners (9, 10). Air is supplied to each individual burner so that air encloses a burner completely.
