Abstract

The utility model provides a mobile combustion boiler. The utility model is characterized in that a water jacket is fixed in a boiler body, and the upper part of the boiler body is divided into a coal storage chamber and a heat change chamber by the water jacket; a combustion chamber which is communicated with a wind chamber via fire grates is arranged on the lower part of the water jacket. The water jacket forms a sloping shape, and a combustible gas secondary combustion chamber is formed by the tail end of the water jacket and the boiler wall of the heat change chamber, so smoke can fully combusts; owing to the sloping shape of the water jacket, the coal storage chamber with a narrow upper part and a wide lower part is formed, and the structure of the coal storage chamber is favorable for the automatic down-slippage of coal by means of self weight. The utility model has the advantages of simple structure and low cost and can effectively reduce the discharge concentration of the smoke.

Description

The flow burning boiler

Technical field:

The utility model relates to a kind of small-sized civil heating coal-burning boiler.

Background technology:

At present, traditional boiler is generally double-grate boiler, back firing boiler etc., shortcomings such as big, smoke medicining dust-removing effect difference of flowing resistance and labour intensity was big when there was burning in it, Chinese patent CN211146311Y discloses a kind of continuous coal-fired normal-pressure boiler, it comprises body of heater, coal storage case, combustion chamber and air compartment, and coal storage case and combustion chamber communicate, and is connected by vertical grate between combustion chamber and burner hearth, chimney arch is arranged in burner hearth, between chimney arch and the hearth wall quirk was arranged.This structure can be burnt coal 40 hours continuously, but because flame directly passes through fire grate and enters the combustion chamber, and be close to red-hot coal, fire grate burns out easily, and the repair rate height has increased cost greatly, and coal storeroom is the square structure that upper and lower area equates, the easy frame of coal cinder can not fall in the coal storage case automatically, influences coal-fired effect.

Technology contents:

The purpose of this utility model provides the flow burning boiler of a kind of efficiency of fire coal height, good dedusting effect.

The utility model is achieved in that a kind of flow burning boiler, comprise body of heater, coal storeroom, Heat Room, combustion chamber, fire grate and air compartment, the combustion chamber is communicated with air compartment by fire grate, it is characterized in that: in body of heater, fix a water leg, water leg is divided into coal storeroom and Heat Room with the top of body of heater, the upper end of water leg is skewed, and its terminal furnace wall with Heat Room forms a fuel gas secondary combustion chamber.

On a wing furnace wall of Heat Room and combustion chamber, can be provided with refractory lining, mutual superposition about two refractory linings, the outside of the refractory lining in the combustion chamber is a slope shape.

On refractory lining, can be provided with cast iron wall with flues backplate.Cast iron wall with flues backplate is provided with air inlet.

Body of heater can be for square.

Described fire grate can be reciprocating type flute profile fire grate.

The utility model is owing to adopted said structure, only a water jacket need be set just can be divided into upper of furnace body coal storeroom and Heat Room, and form a fuel gas secondary combustion chamber in the water jacket end, in the combustion chamber, after the bituminous coal heating, but the high temperature burning fume that is produced carries out second-time burning after entering fuel gas secondary combustion chamber and oxygen mix, makes flammable fugitive constituent sustained combustion intact, can not form black smoke.And because the tilted shape of water leg can make coal storeroom form up-narrow and down-wide type, help coal and rely on deadweight to glide automatically, but realize the just effect of continuous burning of coal.

On a wing furnace wall of Heat Room and combustion chamber, be provided with the temperature that refractory lining can improve gas combustion chamber, adjust the ventilation of fuel gas secondary combustion chamber, to guarantee smoke elimination.And owing in the combustion chamber, be provided with the coking that cast iron wall with flues backplate can be avoided coal, on cast iron wall with flues backplate, be provided with air inlet, for the burning of fuel gas provides oxygen.

Description of drawings:

The structural representation of the utility model flow burning boiler shown in Figure 1;

The cast iron wall with flues guard board structure schematic diagram of the utility model flow burning boiler shown in Figure 2;

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

With reference to figure 1, the utility model flow burning boiler comprises body of heater 1, fire grate 11 and air compartment 9, air compartment 9 is positioned at the below of fire grate 11, on square furnace 1 top, fix a water leg 10 that the top of body of heater 1 can be divided into coal storeroom 3 and Heat Room 2, the bottom of water leg 10 is combustion chamber 5, and combustion chamber 5 is communicated with air compartment 9 by fire grate 11.Once coal is added in the coal storeroom 3 during work, because coal storeroom 3 is connected with combustion chamber 5, therefore 5 bottom can be added to the top of coal storeroom 3 to coal from the combustion chamber, because fire grate 11 adopts reciprocating grate, the fire bars of travelling grate, lime-ash is fallen, and wind energy is enough to enter combustion chamber 5 from air compartment.Being shaped as of water leg 10 is skewed, and its end can form a fuel gas secondary combustion chamber 4 with the furnace wall of Heat Room 2, and flammable fugitive constituent is fully burnt, and can make the blackness of smoke evacuation be lower than 1 grade of Lin Geman, reaches a national class environmental requirement.And, help coal and rely on deadweight to glide automatically because the tilted shape of water leg 10 can make coal storeroom 3 form up-narrow and down-wide type.

Be provided with 6,7, two refractory linings of refractory lining mutual superposition about in the of 6,7 on a wing furnace wall of Heat Room 2 and combustion chamber 5, the outside of the refractory lining 6 in combustion chamber 5 is a domatic.Refractory lining 6,7 can improve the temperature of gas combustion chamber, adjusts the ventilation of quirk, to guarantee smoke elimination.On refractory lining 6, be provided with cast iron wall with flues backplate 8.With reference to figure 2, cast iron wall with flues backplate 8 is provided with air inlet 12.Cast iron wall with flues backplate 8 can be avoided the coking of coal, and the air inlet 12 on the cast iron wall with flues backplate 8 for the burning of fuel gas provides oxygen, makes burning more abundant.

The utility model is simple in structure, and cost is low, can effectively reduce smoke dust discharge concentration.Be particularly useful for domestic boiler.
