Abstract

The utility model belongs to a horizontal internal-fired atmospheric hot water boiler. The utility model is characterized in that a water jacket forms an arch shape; the lower part of the interior of the water jacket is provided with a boiler hearth and a small smoke chamber; the front end of the water jacket is provided with a front smoke box; the upper part of the back end of the water jacket is provided with a back smoke box; a second back stroke communicating smoke pipe is arranged between the front smoke box and the back smoke box; a first back stroke communicating smoke pipe is arranged between the small smoke chamber and the front smoke box; the water jacket and the outer surfaces of the front smoke pipe and the back smoke pipe are respectively provided with a heat-insulating layer; the bottom of the both sides of the water jacket is respectively fixed with a fire grate. The air leakage coefficient of the boiler body is zero, and the draught fan is not required in operation. The utility model has the advantages of simple structure, small volume, low cost, no noise, no pollution and strong output force. The utility model is a hot water heating boiler for institution, factories, mines, and schools.

Description

The horizontal internal combustion normal-pressure hot-water boiler

The utility model relates to normal-pressure hot-water boiler, is a kind of horizontal internal combustion normal-pressure hot-water boiler.

At present, the normal-pressure boiler of selling on the market roughly can divide two classes: a class is horizontal external combustion structure, be by water pipe, pyrotechnics pipe, several forms of extreme misery pipe, it is big that these several forms all have complex structure, cost height, volume, shortcoming such as easily leak out, these shortcomings are the insurmountable difficult problems of externally-fired boiler; Another kind of is old internal combustion type normal-pressure boiler, mainly is made of water jacket and flue, and its major defect is the burner hearth difficult arrangement, is subjected to the restriction of boiler capacity, and the furnace water cooling degree is big, the difficulty of catching fire, and colm should not fire.

The purpose of this utility model provides a kind of horizontal internal combustion normal-pressure hot-water boiler, to solve horizontal external combustion normal-pressure boiler complex structure, cost height, volume are big, shortcoming such as easily leak out, old internal combustion type normal-pressure boiler burner hearth difficult arrangement is limited by boiler capacity, and the furnace water cooling degree is big, the difficulty of catching fire should not be fired problems such as colm.

The purpose of this utility model is achieved in that this stove is made of housing, fire grate, burner hearth, water jacket, water outlet base, water sealing (sealing water) pipe, water inlet base and exhaust opening.The bottom is a burner hearth in the water jacket, thereafter there is little smoke-box the end, the water jacket front end has front smoke box, upper rear end has back smoke box, be provided with first backhaul between front smoke box and little smoke-box and be communicated with smoke pipe, front smoke box is provided with second backhaul with the back between smoke box and is communicated with smoke pipe, is equipped with heat-insulation layer at water jacket and forward and backward smoke box outer surface.

Smoke pipe: adopt light pipe or screwed pipe.

Water jacket: be arch or square.

Fire grate: be meant traveling-grate stoker, reciprocal grate or fixed grate.

This utility model compared with prior art has the following advantages: 1) burner hearth is in the little smoke-box of water sleeve, so whole boiler does not need sealing, boiler body part air leakage coefficient is zero, and being in operation does not need air-introduced machine, utilizes the draft of chimney just can reach negative-pressure firing; 2) burner hearth length and width direction has the broad excursion, so the capacity of boiler is unrestricted, and the furnace heating surface fractional cold can change by laying wall with refractory lining, refracto; 3) simple in structure, volume is little, in light weight, cost is low; 4) floor space is little, noiseless, pollution-free, the foot of exerting oneself.

Be described further below in conjunction with accompanying drawing:

Fig. 1 horizontal internal combustion normal-pressure hot-water boiler structural representation;

Fig. 2 A-A cutaway view.

Among Fig. 1-2: housing (1) adopts the iron plate weldering to make, and heat-insulation layer (3) adopts existing insulation material, and water outlet base (4), water sealing (sealing water) pipe (7), exhaust opening (10), water inlet base (12) are same as the prior art.Water jacket (11) is arch or square, burner hearth (14) and little smoke-box (8) are arranged at the water jacket bottom, the water jacket front end has front smoke box (2), upper rear end has back smoke box (9), be provided with first backhaul between front smoke box and little smoke-box and be communicated with smoke pipe (5), front smoke box is provided with second backhaul with the back between smoke box and is communicated with smoke pipe (6), water jacket (11) solid welding is passed on tube sheet in smoke pipe (5), (6), be equipped with heat-insulation layer (3) at water jacket (11) and forward and backward smoke box (2), (9) outer surface, solid welding has fire grate (13) on the bottom surface, water jacket both sides.The combustion of flue gas fire is risen by fire grate, enters front smoke box through burner hearth (14), little smoke-box (8), the first backhaul smoke pipe (5), and smoke box after the second backhaul smoke pipe (6) enters is discharged from exhaust opening (10) then.

Claims
