Abstract

The utility model relates to a contrarily burning type semi gasification constant pressure heating boiler which consists of a coal storing room, a heating room, an ash room, a hose furnace gallbladder and water jackets. The utility model is characterized in that: the four walls of the heating boiler provided with the water jackets which have the interlayer structures and an interlayer water jacket which has an interlayer structure is arranged between the coal storing room and the heating room divides the heating boiler into two hearths, the canal furnace gallbladder of the heating room is communicated with the water jackets on the side wall and is connected with a water outlet pipe; and the side wall of the heating room is provided with an inclined water jacket which is connected with the water jackets on the side wall. The utility model has the advantages that: the utility model is additionally provided with the coal storing room; the heating boiler can normally run; the utility model can keep burning more than 6 hours for being added coal once, thereby decreasing the time of the coal adding; the utility model adopts the technique of the coal storing semi contrarily burning; therefore the continuities of the warm-up, deiccation, carbonization, burning, exhausting burning of the coals are realized; the utility mdoel solves the problem of reducing the temperature of the hearth caused by the being directly coal added; the heat efficiency is obviously elevated.

Description

Reverse combustion type half gasfication atmospheric heating boiler

Technical field

The utility model relates to a kind of domestic heating boiler, particularly a kind of reverse combustion type half gasfication atmospheric heating boiler.

Background technology

At present, general normal-pressure boiler all is that burning and heating process are placed in the same fire grate combustion chamber, in burner hearth cavity and flue water jacket is housed, and water forms thermal cycle gradually by the continuous heating of burner hearth, thereby plays the purpose of heating.It is slow to get angry when this boiler uses, and the thermal efficiency is low, and coal easily causes the fire box temperature instability often, and coal utilizaton rate is low.

Summary of the invention

In order to address the above problem, the utility model provides a kind of and will burn and the high reverse combustion type half gasfication atmospheric heating boiler of the thermal efficiency that heating clamber separates.

The technical solution adopted in the utility model is: a kind of reverse combustion type half gasfication atmospheric heating boiler, constitute by coal storeroom, heating clamber, grey chamber, water pipe flue and water jacket, it is characterized in that, the wall of heating boiler is the water jacket of sandwich, and the interlayer water jacket that is provided with sandwich between coal storeroom and the heating clamber is divided into two burner hearths with heating boiler, and the water pipe flue of heating clamber communicates with the water jacket of sidewall and links to each other with outlet pipe; The heating clamber sidewall is provided with an inclination water jacket and links to each other with the sidewall water jacket.

Compared with prior art, advantage of the present utility model is: set up coal storeroom, heating boiler normally moves, and a sustainable burning of coal reduced the coal number of times more than six hours; Adopted coal storage formula half anti-burning technology, realized preheating, drying, destructive distillation, the burning of coal, the continuity of after-flame, solved the problem that reduces fire box temperature because of direct coal, the thermal efficiency is significantly improved.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:

Embodiment 1: see Fig. 2, a kind of reverse combustion type half gasfication atmospheric heating boiler, constitute by coal storeroom 13, heating clamber 14, grey chamber 12, water pipe flue 16 and water jacket, the wall of heating boiler is the water jacket of sandwich, and the interlayer water jacket 11 that is provided with sandwich between coal storeroom 13 and the heating clamber 14 communicates with the top water jacket, heating boiler is divided into two burner hearths, and the water pipe flue 16 of heating clamber 14 communicates with the water jacket of sidewall and links to each other with outlet pipe 7; The heating clamber sidewall is provided with an inclination water jacket 15 and links to each other with the sidewall water jacket.

During coal coal is put into coal storeroom 13 from firing door 10, interlayer water jacket 11 separates coal storeroom 13 with heating clamber 14, heating boiler is divided into two burner hearths, thereby realized that heating separates with the burning operation, coal is at coal storeroom's 13 base burnings, flame makes progress in heating clamber 14 to water pipe flue 16 heating of its inside, thereby has realized the backfire heating.Ashes in the heating clamber 14 can successfully be slided ash entrance chamber 12 by inclination water jacket 15, and water pipe flue 16 communicates with the sandwich water jacket of sidewall and links to each other with outlet pipe 7, has reached the purpose of heating.

Embodiment 2: as shown in Figure 3, a kind of reverse combustion type half gasfication atmospheric heating boiler, constitute by coal storeroom 13, heating clamber 14, grey chamber 12, water pipe flue 16 and water jacket, the wall of heating boiler is the water jacket of sandwich, and the interlayer water jacket 11 that is provided with a plurality of sandwiches between coal storeroom 13 and the heating clamber 14 is divided into several sections with heating clamber, the setting of a plurality of interlayer water jackets can increase the time of staying of flame in heating clamber 14, water pipe flue 16 in the heating clamber 14 is heated more comprehensively, has further improved the thermal efficiency of heating boiler.
