Abstract

PURPOSE:To prevent the device from the red-flame and the generation of odor by a method wherein the fuel delivery rate of an electromagnetic pump is changed in stepless or stepped manner in accordance with the changing of a burning air quantity from a blowing fan. CONSTITUTION:A fan 1 has two steps of blowing capability, a strong and a weak air flows generated by the fan are controlled by the signals from wirings 2-a, 2-b in a control circuit 2. An electromagnetic pump 3 has four steps of fuel delivery capability which is designed so that the fuel delivery capability is controlled to be decreased in order by the signals from wirings 2-a', 2-b', 2-c' and 2-d' in the control circuit 2. By changing the signal from the control circuit 2 from the 2-a to the 2-b for decreasing the burning quantity, the air flowing quantity of the fan 1 is gradually decreased; slowing the number of revolutions down to the one set by the signal of the wiring 2-b requires several seconds. During the several seconds, the signals from the wirings 2-a' to the 2-d' of the control circuit 2 are sent in order and the fuel delivery quantity from the electromagnetic pump 3 is gradually decreased.

いた。(b) Problems to be solved by the invention In conventional hot air heating systems, when changing the combustion amount, especially when reducing the combustion amount, even if the rotation speed of the blower fan is lowered, the rotation speed will decrease due to inertia. This does not change immediately.On the other hand, the amount of fuel discharged from the electromagnetic pump changes instantly, which can cause an imbalance between combustion air and fuel, causing incomplete combustion, resulting in red-flame combustion and abnormal odors. In addition, as a method to solve the above-mentioned problem, it is common practice to use a solenoid valve to change the width of the combustion air inlet, but if it becomes clogged with dust or the number of times it is used increases, The control function of the valve was degraded, making it ineffective in practice.

The ejection capacity is sequentially decreased from the former by the signal from c' 2 d'. In order to reduce the amount of combustion, when the control circuit ■ signal is changed from 2-a to 2-b, the air flow rate of 77-inch ■ gradually decreases, and the wiring 2-b
It takes several seconds to reach the signal rotation speed. During those few seconds, signals are sequentially sent to the wirings 2-a' to 2-d' of the control circuit (2) to gradually reduce the amount of oil discharged from the electromagnetic pump (2).

As a result, red flame combustion and strange odors were eliminated, which had an outstanding effect on improving the performance of hot air heaters6.
