Abstract

PURPOSE:To slowly burn only the outer peripheral part of a flame as a combustion part and to reduce a combustion sound by setting the distribution of ratio of the quantity of primary air with respect to the total sum of quantities of primary air and secondary air of the partially premixing type burner to a specific value or less. CONSTITUTION:The distribution ratio of primary air with respect to the total sum of quanties of primary air and secondary air is set to 0.3 or less. A fuel gas is supplied from a gas supply tube 3c to respective burners 1a, and a part of air supplied from a blower 2a to a gas supply chamber 2 is circulated to a mixed gas chamber 3 as primary air (b) and another part thereof is introduced into a secondary air passage 1b as secondary air (c). Primary air 1b is sent to respective burners 1a... together with a fuel gas (a) discharged through gas supply nozzles 3a1 and mixed with the fuel gas 1a within a mixing route 1a2 so as to be formed into an air mixed gas (d) which is discharged through burner ports 1a11... of the burners 1a....
