JPS599166Y2 - Oil combustor air volume adjustment device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an air volume control device for an oil combustor.

The applicant of this application first opened and closed a damper interposed in the combustion air supply passage in conjunction with the oil volume adjustment operation of the oil volume regulator, thereby linking the switching between the supply oil volume and the combustion air supply volume. I suggested it earlier.

However, since there is no draft at the beginning of combustion, the air volume is insufficient and the transition from ignition to stable combustion is slow and there are other disadvantages such as soot generation.

The purpose of the present invention is to obtain a device that eliminates such inconveniences, and an oil amount regulator 4 is provided in the oil supply path 3 of the oil combustor 2 equipped with an exhaust pipe 1. Amount regulator 4
In the type that adjusts the opening degree of the damper 7 interposed in the combustion air supply path 6 in conjunction with the adjustment operation of the oil amount adjustment knob 5, the oil amount adjustment knob 5 side and the damper 7 are connected. The middle of the connecting wire 8 is engaged with an actuator 9 that senses the heat radiation temperature of the combustor 2 and swings the damper 7 toward the closing side.

In the illustrated example, a cam piece 10 is provided on the oil amount adjustment knob 5, a wire 8 is connected to the other end of a lever 11 with one end facing the cam piece 10, and the other end of the wire 8 is used for combustion. It is connected to a lever 7b on the support shaft 7a of the damper 7 provided at the discharge port 12a of the blower 12 as the air supply path 6, and when the oil amount adjustment knob 5 is rotated, the damper 7 is oscillated via the wire 8. This is not particularly different from the previous proposal.

In the drawing, 13 is a spring that pulls the damper 7 toward the opening side.

The present invention is such that the middle of the wire 8 is locked to an actuator 9 that senses the heat radiation temperature of the combustor 2 and pulls the wire 8 to the tension side. consists of a bimetal 9a that operates by sensing the temperature of the heat sink 14, and a lever 9b connected to the bimetal 9a.The wire 8 is locked to one end of the lever 9b, and the bimetal 9a is attached to the other side. When the temperature of the combustion tube 14 rises when the free ends are brought into contact, the lever 9b is rotated to the side where the wire 8 is tensed by the bimetal 9a.

In this case, in a device designed to ignite at the initial low flow rate combustion position, the damper 7 is in an open state because the tension on the wire 8 caused by the actuator 9 is released at the beginning of ignition.

Therefore, when enough air is obtained for combustion and the transition from the start of combustion to normal combustion begins, the transition to normal hot combustion occurs, and when a draft occurs, the actuator 9 operates and swings the damper 7 toward the closing side. let

Therefore, even after transition to normal combustion, the air volume will not become excessive.

In this way, according to the present invention, the middle of the wire 8 that connects the oil amount adjustment knob 5 side and the damper 7 is connected to the actuator 9 that senses the heat radiation temperature of the combustor 2 and pulls the wire 8 toward the tension side. Since it is locked, sufficient combustion air can be supplied when combustion starts, and when the heat dissipation temperature rises, the actuator 9 tensions the wire 8 and closes the damper to some extent. , and has the effect of providing stable combustion even during normal combustion.
