Description

{Stack Structure for Gas Heater}

The present invention relates to a stove for a gas heater, and more particularly, to a stove for a gas heater that greatly improves operational convenience and safety when lifting a chimney for a natural gas gas heater for disassembly or assembly.

 In general, natural gas is supplied through pipelines piped to the underground, which is once extended from the three natural gas production bases (Incheon, Tongyeong and Pyeongtaek) to the fence boundary of city gas companies or power stations in each region.

 The natural gas produced at the natural gas production base is supplied to the regional supply station through the above-mentioned pipe network, and then supplied to the city gas companies or power plants of the respective regions. Through the city gas companies, the natural gas is supplied to each home, office, It is supplied to the same place of use.

 As described above, natural gas is normally supplied at a reduced pressure of 65 to 75 kg / cm 2 when supplied from a gas supply station to each use place. At this time, when the hydrodynamic pressure is reduced, natural gas The amount of heat is greatly reduced.

 Natural gas is heated to natural gas calorie control device before it is supplied to each use place in the gas supply station, that is, before it is depressurized, and the calorie is supplemented by the natural gas calorie management device. The natural gas calorie management apparatus uses a gas heater using natural gas as fuel.

 The gas heater is equipped with an oven which is a cylindrical heavy weight for protecting the equipment which may be damaged by flame and heat of the burner. The furnace has an outer tube portion supported by an inner circumferential surface of a fire tube of a gas heater body and an inner tube portion spaced apart from the outer tube portion, and a castable structure is formed between the outer tube portion and the inner tube portion.

The furnace is provided with a chimney for discharging the combustion gas generated during combustion, and the chimney is disassembled and assembled at the regular inspection of the gas heater facility.

The chimney is connected to a crane when it is disassembled or assembled, and the operator directly hooks the upper ring provided on the upper surface of the chimney and the hook provided on the wire of the crane.

That is, when lifting the chimney for maintenance of the gas heater, the upper part of the upper surface of the chimney provided at a height of 5 m or more is connected to a hook provided on the wire of the crane, And is working on a complaint.

However, the conventional lifting operation of the chimney has a problem of causing a safety accident during the elevating operation in which the operator connects the upper ring provided on the upper surface of the chimney to the hook provided on the wire of the crane at a height of 5 m or more .

In addition, there is a problem in that a worker has to separately prepare a boarding box to be boarded, and that the boarding box must be connected to the wire of the crane for hoisting, which increases the work cost and complicates the lifting operation and takes a long time .

FIGS. 6 and 7 are schematic views showing a process of lifting a stack structure for a gas heater according to the present invention, FIGS. 6 and 7. FIG.

6, the worker may move the chimney body 10 in a state where the length of the turnbuckle 43 is increased to lift the chimney body 10 from the ground or the floor of the chimney 10, The turnbuckle 43 and the lower end side connecting claw portion 40a of the connecting string member 41 are separated from each other on the side of the lower side sill 30 on both sides of the connecting string member 41 To the lifting hook (2) of the lifting work wire (1), respectively.

FIG. 7 illustrates the operation of lifting the chimney main body 10 by operating the crane in a state where the connecting wire member 41 and the lifting work wire 1 are connected as shown in FIG.

7, the lower end side of the hoisting operation connecting portion 40 connected to the hoisting working wire 1 of the crane through the lower connecting link 40a of the connecting line member 41 is connected to the lower end side of the crane And the chimney main body 10 is connected to the lifting work connecting part 40 lifted by the crane and is lifted together.

After the lifting of the chimney main body 10 to a desired position, that is, an assembling position or a position where the chimney main body 10 is separated and stored, the lifting work connecting line 40 is separated from the lifting work wire 1, And the length of the turnbuckle 43 is shortened after being connected to the hook 30, so that the turnbuckle 43 is firmly fixed to the lower side hook 30.

Although not shown, the turnbuckle 43 is separated from the lower side ring 30 provided on both sides of the chimney main body 10, and the separated turnbuckle 43 is used for the lifting work It is also possible to connect the lifting hook 2 of the wire 1 to operate the crane so as to raise the chimney body 10 on the same principle as above.

This design enables the worker to connect with the crane for the lifting of the chimney from the ground, which greatly improves the safety of the lifting operation without causing the operator to fall due to the elevated work.

The present invention eliminates the need to separately prepare a boarding structure such as a boarding box on which a worker boarded for a high-altitude work, thereby improving work convenience in lifting work and greatly reducing work time and cost.

It will be understood by those skilled in the art that various other changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. will be.
