Title: Burner
Inventor: HASHIDO KENKICHI
IPC: F23N5/24
Filed: 1988-08-11
Abstract: PURPOSE:To control a primary combustion air in proportion to a combustion volume, supply a specified volume of a secondary air, eliminate the trouble of dew condensation even when the combustion volume is reduced, easily control the primary air volume with accuracy, and eliminate the danger of imperfect combustion and the like by controlling the rotary speed of a primary blower. CONSTITUTION:When a room temperature approaches a specified temperature, a combustion volume control means 27 outputs a combustion volume so that it may be reduced gradually. At the same time, the control means changes a pump 16 and a primary air volume simultaneously by controlling the rotary speed of a primary blower 18. During the above performance, a secondary blower 20 supplies a specified volume of air without changing the air volume as it is. When the density of exhaust gas is reduced, dew condensation is minimized even when the combustion volume is reduced, thereby eliminating the generation of rust due to the inflow of dew drops into a heat exchanger 13 or the danger of blockage of an exhaust pipe 15 due to iced dew drops. The primary air, which affects the combustion performance greatly, is controlled by the rotary speed control of the primary blower 18, which makes it possible to control easily the air volume with high accuracy, maintain the balance between the air and fuel, and eliminate the danger of imperfect combustion.
