Abstract

An air inflow regulating apparatus for a burner is provided to reduce the volume of the burner by attaching the air inflow regulating apparatus directly to a vehicle body. An air inflow regulating apparatus for a burner(A) includes a regulating unit attached directly to the burner to regulate an air inflow rate by permitting an air inflow regulating plate(C) to move back and forth, and open or close a combustion air supply unit(a1). The air inflow regulating plate includes a cylinder(10), a cylinder rod(11), a connection member(12), a travel bar(13), and a travel bar housing(14). The cylinder is attached to one end of the burner, and generates force for moving the air inflow regulating plate. The cylinder rod moves in a forward or backward direction on the basis of the force generated by the cylinder. The connection member is joined to the cylinder rod and the travel bar so as to transmit reciprocating motion of the cylinder rod to the travel bar. The travel bar is joined to the connection member, and has an end connected to the air inflow regulating plate so as to transmit the reciprocating motion of the cylinder rod transmitted by the connection member to the air inflow regulating plate. The travel bar housing is arranged to house the travel bar such that the travel bar is prevented from escaping from its axis of movement due to the weight of the air inflow regulating plate.

The present invention relates to an air inlet control device for a composite burner, and more particularly, an additional device for adjusting the air inflow amount is attached directly to itself instead of being configured separately from the composite burner, thereby reducing the volume of the entire equipment and controlling the air inlet control plate. It is related with the air inflow control apparatus of the combined burner which can control the air inflow quantity finely because the adjustment interval of is not determined.

In general, the by-product gas of steel mills includes blast furnace gas (BFG) by-product from blast furnaces, converter gas (LDG: Linz-Donawitz gas) generated during the steelmaking process, and coke gas (COG) produced by coke production. Coke oven gas is used to operate the self-fired power generation boiler of the steel mill using the by-product gas.

However, these by-product gases have a plurality of burners corresponding to each by-product gas because not only the amount of heat generated by the steel mill is different but also the amount of each of them produced.

Since each of the burners is essentially provided with auxiliary equipment such as a fuel supply device, a combustion air supply device, and an ignition device, the total size of the boiler is increased to accommodate such auxiliary equipment.

In order to solve the above problems, by combining the characteristics of each burner that burns by-product gas generated in steel mill and heavy oil which is purchased fuel, it is possible to burn various kinds of fuels by constructing one body and also by-product gas. According to the supply amount, a composite burner that can flexibly select and burn combustion fuel is used.

The composite burner is provided with a plurality of combustion air supply parts for supplying air required for combustion of by-product gas and heavy oil, and the combustion air supply part is opened and closed by an air inlet control plate slid along the outer surface of the compound burner. By controlling the supply amount and by adjusting the air supply amount according to the type of the by-product gas to maintain a stable flame state at all times.

However, in the conventional air inflow control device having the above configuration, since the additional equipment for controlling the air inflow amount is configured separately from the composite burner, the total volume of the composite burner is extensive, so that a lot of time is required for maintenance of the composite burner and maintenance of the additional equipment. There was a problem, and in adjusting the air inlet control plate, as the size of the gear teeth of the drive gear and the guide bar gear and the distance between each gear is adjusted by the minute or less than the size of the gear teeth There was a problem that can not be adjusted.

In addition, in the forward and backward movement of the air inlet plate, it was troublesome to visually determine the stop at the forward and backward movement limit point of the air inlet plate to operate and deactivate the drive gear.
