The method of atomization is adopted. Therefore, in order to atomize all the fuel 38 into fine particles, the high-pressure compressor must supply the high-pressure atomizing air 40, which causes a problem that the device becomes expensive. It is possible to use a low pressure air atomization burner to solve this problem.For example, in a low pressure air atomization burner typified by a proportional adjustment type oil burner, a fuel and air adjustment mechanism is provided inside the burner body. Since it is built in, the temperature of the adjusting mechanism rises due to the radiant heat of the furnace depending on the operating conditions, which often causes a malfunction due to seizure. In this specification, the high pressure air is 5000 mmA.
