The utility model is that water tubes (4) of fire bars are arranged at the bottom of a common stove cavity, a concrete-proof jacket (5) is arranged around the common stove cavity, a rectangular upwarp (6) of the stove cavity is arranged on the top cover, the upwarp is composed of a pair of heating water pipes (8), the top of a top carriage stove cavity is made of steel plates, the bottom of the top carriage stove cavity is covered with fire-proof concrete, Y-shaped air stack steel plates (1) which are upright in the direction of a stove grate are arranged at both sides of the stove cavity, the top of the stove cavity is closed, the lateral surface is provided with a plurality of combustion supporting holes, the air stack steel plates form a preheating air stack with the inner wall of the stove, and the stove cavity (13) is provided with a combustion chamber (15). Owing to the radiant heat of the upwarp of the stove cavity and the fire-proof concrete jacket, the utility model has the advantages of high stove temperature, sufficient combustion of coal, and high efficiency of smoke prevention and dust control.

Description

The smoke elimination drinking water boiler

The utility model relates to and is used for fire coal, combustion gas drinking water boiler, particularly vertical fire coal stove.

The utility model improves development and comes on public vertical drinking water boiler basis.

Commercially available Coal stove for making tea mostly is that coal burns at burner hearth, and furnace bottom property next time burns to wind, the direct heat hot water pipe of flame, and the coal combustion is insufficient, and the thermal efficiency is low, and flue dust is big.

The purpose of this utility model is that design is a kind of simple in structure, can smoke abatement and dust control, can improve the drinking water boiler of the thermal efficiency again.

Technical solution of the present utility model is, establish fire bars water pipe (4) at public vertical drinking water boiler burner hearth bottom, establish refractory concrete cover (5) on every side, loam cake rectangle furnace arch (6), arch is by a pair of heating pipe (8), put on the shelf under the steel plate of burner hearth top with the topped formation of refractory concrete, both sides have the air channel steel plate (1) of thirty years of age of suitable internal protecting wall and internal protecting wall constitutes pre-hot-flow flue (17) and the burner hearth arch constitutes burner (20), the steel plate tip side has a plurality of combustion-supporting holes (2), sets up combustion chamber (13) on the burner hearth (13).

The utility model is compared its advantage with public vertical drinking water boiler and is, and is simple in structure, catches up with fire fast, and firepower is violent, not flame-out.In addition, coal burns at burner hearth, and both sides increase pre-hot-flow flue, and is combustion-supporting by combustion-supporting hole ejection elevated temperature heat air-flow and burner hearth, the abundant mixed combustion of fugitive constituent, burner hearth have the fire-resistant coagulation of refractory concrete cover and burner hearth crown, increase the burner hearth heat radiation, improve furnace temperature, make the coal combustion fully, thermal efficiency height.

Following accompanying drawing is described embodiment of the utility model.

Fig. 1 is the utility model side sectional side elevation.

Fig. 2 is a burner hearth front organigram.

The utility model specifically can be implemented like this, make of metallic plate, furnace wall (18) overcoat upper side is provided with inspection socket (9), there are ash door (11), grey chamber (3), flue (19) in the front, bottom, outsourcing water jacket (7), and continuous by fixing dragline (16), upper top is provided with flue (10), interior in, top is provided with the different heating pipe of multilayer direction (8).Burner hearth (13) is arranged at the bottom, there is the coal stove door of adding (12) in the front outside the bottom, see burner (14), burner hearth bottom is provided with many fire bars water pipes (4), build refractory concrete cover (5) on every side, loam cake rectangle furnace arch (6), it is refused is by a pair of heating pipe (8), the burner hearth top steel plate of putting on the shelf, cover with refractory concrete down and constitute, herringbone air channel steel plate (1) and internal protecting wall that both sides have thirty years of age of suitable furnace wall constitute pre-hot-flow flue (17), seal in the top, arch constitutes burner (20) with burner hearth, steel plate (1) side, top has a plurality of combustion-supporting holes (2), and combuster on the burner hearth (5), its heating tube all communicate with the drinking water boiler water jacket.

The drinking water boiler tool is work like this, when adding coal combustion, opens in burner hearth ash door air intake, part wind enters burner hearth through the fire bars heating pipe and helps coal combustion, another part wind spray from combustion-supporting hole through pre-hot-flow flue preheating, mixes with fuel gas that the burner hearth unburned finishes to enter the combustion chamber through burner and carry out second-time burning.Refractory concrete cover and arch refractory concrete overcoat have been increased in the burner hearth, because heat radiation effect, improved furnace temperature, further make coal combustion fully, it is many that heat is emitted in smoke abatement and dust control, and hot-fluid is by from bottom to top flowing in the flue, obstruction through the multilayer heating pipe, extend contact time, increased contact-making surface, so improved the thermal efficiency.

Claims (2)

1. smoke elimination drinking water boiler, constitute by furnace wall (18) and flue (19), furnace wall (18) upper side has inspection socket (9), there is ash door (11) in the front, bottom, ash chamber (3), flue (19) outsourcing drinking water boiler water jacket (7), and link to each other with furnace wall (18) by fixing dragline (16), upper top has flue (10), there is heating pipe (8) interior middle and upper part, and burner hearth (13) is arranged at the bottom, and there is the coal stove door of adding (12) in the front outside the bottom, see that burner (14) constitutes, its feature burner hearth bottom has fire bars heating pipe (4), establish refractory concrete cover (5) on every side, loam cake rectangle furnace arch (6), both sides have the air channel steel plate (1) of thirty years of age of suitable internal protecting wall, pre-hot-flow flue (17) with the internal protecting wall formation, have the air channel to become burner (20) with arch on the burner hearth, steel plate (1) tip side has a plurality of combustion-supporting holes (2), and combuster on the burner hearth (15) constitutes.

2. according to the described smoke elimination drinking water boiler of claim (1), its feature burner hearth arch (6) is by a pair of heating pipe (8), puts on the shelf under the steel plate of burner hearth top with the topped formation of refractory concrete.
