Title: Hot water supplying device reduced generation of nitrogen oxide
Inventor: SUGAWARA TATSUYA
IPC: F24H1/14
Filed: 1991-07-26
Abstract: PURPOSE:To reduce the generation of nitrogen oxide in a hot water feeder. CONSTITUTION:The combustion heat of flame is effectively adsorbed by means of water pipe 7 for reduce the generation of NOX installed in a proper region between a highmost flame temperature region in a laminar flow flame formed on the downstream side of a burner flame hole and the burner flame hole and a flame temperature in a highest flame temperature region on the downstream side is reduced. This constitution reduces an amount of generating NOX while suppresses the generation of CO. Since the pipe 7 for reducing the generation of NOX is connected to the supply water system water pipe 2 or a hot water system water pipe 3 in the hot water supplying device 1 in a manner to branch therefrom and join therewith, an absorption heat is effectively utilized.
