Patent JP-H06207707-A (JP)
Title: Boiler
Inventor: NAKAMURA SUNAO
IPC: F22B7/16
Filed: 1993-01-11
Abstract: PURPOSE:To reduce the size of a gas boiler and inhibit the generation of NOx and enhance boiler efficiency and minimize combustion noise by supplying pre-mixed gas to a burner consisting of a sintering board made of metal or ceramic-made fiber. CONSTITUTION:A burner 21 provides two burner plates laid out in parallel at a given span and closes their tip. The burner plates are formed with a stainless steel-made long fiber raw material sintered and provides a porosity in the range of 85 to 95%. Therefore, if the pre-mixed gas is supplied to the burner plates, the pre-mixed gas will be sprayed from the whole surfaces of the burner plates equally. Then, the pre-mixed gas is ignited, flames will spread all over the surfaces of the burner plates, form plane flames and start combustion, thereby preventing the flames from being separated far from the surfaces of the burner plates. The radiation heat generated from the plane flames overheats a boiler drum water in water tubes 20 and 22. This construction makes it possible to eliminate the need for a combustion chamber and reduce NOx with lowered flame temperature and enhance boiler efficiency as well.
