JPS6410009A - Pulse combustor - Google Patents

Abstract

PURPOSE:To modulate the operation time of a combustor fan with the transition to a stabilized burning so as to maintain the stable burning regardless of ambient conditions by providing a control means which controls the suspension time of the combustor fan in accordance with the temperature outputted from a temperature sensor in the combustion chamber. CONSTITUTION:If the temperature is low in the mixing chamber 2a, the operation of combustor fan 11 is continued until a stabilized temperature is outputted to a control device 14. When such a temperature is reached, the combustor fan 11 is suspended, and a self-controlled combustion (pulse combustion) is formed where 'ignition, expansion and exhaust' and 'air feed' and repeated. If the temperature in the mixing chamber 2a is high, a stabilized combustion is assumed in a very short period of time, and so, the fan is suspended and the self-controlled combustion takes place when the minimum operation time A is past after the ignition. Since the time period of suspension of the combustor fan 11 is dependent on a time interval from one combustion condition to a stabilized combustion, the stabilized combustion can be obtained regardless of outside temperature, etc.
