Abstract

The utility model relates to an improved technology of a normal pressure boiler. The structure is composed of an upper part, a middle part and a lower part. The lower part is a slag outlet part. The middle part comprises a hearth and a fuel chamber. The fuel chamber is divided into an upper fuel chamber and a lower fuel chamber. A plurality of radiative heat receiving tubes is arranged in the hearth for increasing the heated area. The utility model has the advantages of simple structure, stable burnt and convenient installation and use. The water in the boiler is heated via a radiative tube. The sheath is a heat preservation layer. Double fuel chambers and a reversal combustion mode are adopted. The thermal efficiency is high. The energy sources are saved and the environmental pollution is reduced.

Description

The anti-normal-pressure boiler that burns of horizontal smokeless

The utility model belongs to a kind of normal-pressure boiler improvement technology, is adapted at installing and using in the various normal-pressure boilers.

At present, normal-pressure boiler is extensively promoted the use of, and its benefit is simple in structure, easy to install, great advantage is a security of operation, has reduced the various accidents that produce owing to high-pressure bottle, it is vertical that structure mostly is, and radiation heating-surface is housed in the burner hearth, is heat transfer medium water around the body of heater, the body of heater top is connected with radiator by pipeline, its deficiency is, this kind boiler efficiency is low, and a large amount of fuel combustions are insufficient, run off from flue, cause pollution surrounding environment.

For solving above boiler structure deficiency, the purpose of this utility model provides the anti-normal-pressure boiler that burns of a kind of horizontal smokeless, radiation heat pipe and water pipe furnace grate and double fuel chamber are housed in boiler furnace inside, effectively solved current use boiler thermal output not high, to the surrounding environment pollution problems.

Structural design of the present utility model is achieved in that this normal-pressure boiler body of heater forms (as shown in Figure 1) by upper, middle, and lower part, the bottom: be the slagging-off part, positive for splitting air door, the side has slag notch; The middle part: in the body of heater is burner hearth, burner hearth is a fuel chambers, fuel chambers has two coal chambers, in the middle of the coal chamber is water pipe furnace grate, fuel input port separately is equipped with in each coal chamber, and the inside, following coal chamber has logical burner, and casting furnace grate is equipped with in this coal chamber bottom, a plurality of laterally spaced radiation heat pipes all are housed in burner hearth, increase heating surface area; Top: be the burner hearth flue, deflection plate is equipped with in the flue tube bottom, and the body of heater topmost is a smoke exhaust pipe, and the body of heater outside is a heat-insulation layer, and whole body of heater is an integral body, and the bottom is a horizontal type structure, and top is vertical structure.

The utility model advantage is: simple in structure, and flameholding, easy to install, by radiant tube water in the stove to be heated, crust is a heat-insulation layer, adopts the double fuel chamber, the anti-mode of burning, thermal efficiency height, energy savings reduces environmental pollution.

Detailed structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1 is the anti-normal-pressure boiler overall construction drawing that burns of horizontal smokeless;

Fig. 2 is the anti-normal-pressure boiler front elevation that burns of horizontal smokeless.

Its structure as shown in drawings, the bottom for the slagging-off part, side 1 is a dedusting mouth, positive 20 for removing cinder notch, is burner hearth in the flue, and outside 2 is horizontal external furnace body, 3 is horizontal inner furnace body, and it is heat-insulation layer that radiation heat pipe 4,5 is housed in the burner hearth, the vertical part in top, 6 is vertical ectosome, 7 is vertical endosome, 8 is deflection plate, for reducing heat loss, improves the thermal efficiency, 9 is smoke pipe, and 10 is furnace roof, and 11 is flue flange, horizontal body of heater positive 12 is the dedust mouth, 13 is secondary smoke exhaust pipe, and horizontal body of heater front upper 14 is a main fuel chamber, and bottom 18 is secondary fuel chambers, 15 is the main fuel port of throwing, 17 is the secondary fuel port of throwing, and 16 is water pipe furnace grate, and 19 is casting furnace grate.

Its course of work is after boiler is heated, and the boiler top is hot water and saturated vapor, because radiant tube is heated in burner hearth, area is big, double fuel chamber refuelling, so improved the thermal efficiency greatly, fuel combustion is abundant, the fire box temperature height is not smoldered, and has very big social benefit and economic benefit.
