发明名称 COMBUSTION CONTROLLER
摘要 PURPOSE:To expand a variable regulating range for heating quantity of combustion in a hot water supplyer or a hot water-heating system by a method in which a proportional burner and a switching burner are connected in parallel, heating quantity in large stages is set up by combining the switch burner groups, and an intermediary stage is continuously varied by the proportional burner. CONSTITUTION:A main gas valve 15 is provided in a gas path 14 and the downstream is branched into three. A proportional burner 17 through a proportional controller 16, a first switch burner 19 through a valve 18, and a second switch burner 21 through a valve 20 are provided in parallel. A switch burner group 22 is made of the burner 19 and the burner 21. A water flow switch 25 is also provided in a water supply path 24 leading to a heat exchanger 23, and a sensor 27 for the temperature of hot water is provided in a hot water supply path 26. Signals from these are sent to a controller 28. In this case, the heat quantity of the switch burner group 22 is set to meet a relation of geometrical progression wherein the first term is less than variable regulating the range of the burner 17 and the common ratio is 2 to eliminate the stepwise change of the heat quantity and also to reduce the number of valves for the switch burner to a minimum. If the controllable range of heat quantity is widened in this way, more easy-to-use supplyer for hot water of stable temperature can be obtained.
