Title: Combustion apparatus for hot water supply
Inventor: WATANABE HIROAKI
IPC: F23N3/00
Filed: 1983-06-23
Abstract: PURPOSE:To miniaturize an apparatus, and to save space by stabilizing the quantity of primary air induced by fuel regardless of the pressure of combustion air by bypass action by a load section. CONSTITUTION:Since a primary air chamber 18 is connected to a negative pressure section 22 made more negative than the pressure of a combustion chamber 24 through a communicating port 20, air flowing into the primary air chamber 18 functions as a suction to the negative pressure section 22 side, and the quantity of primary air from a primary air port 16a hardly increases, and is controlled naturally by characteristics depending upon the injection pressure of fuel. When high TDR combustion is executed through the control of the quantity of combustion by a fuel control valve 26, the opening of a movable damper 21 in the communicating port 20 is increased to augment the quantity of bypass of primary air to the negative pressure section 22, and quantity of the primary air side is reduced. Accordingly, an apparatus can be miniaturized and space saved, while the stability of combustion can be improved.
