PULSE BURNERS

摘要

In a pulse burner of the type wherein an airfuel mixture in a combustion chamber is explosively burnt by an ignition plug, a flapper valve repeatedly opens and closes an air inlet passage and a fuel inlet passage so as to repeat explosive combustion of an airfuel mixture at a high frequency, there is provided a flame detector which interrupts the ignition plug and a fan for supplying air into the combustion chamber once the combustion has started normally. According to this invention, it is not necessary to supply electric energy for operating the ignition plug and the fan during normal operation.
