Description

The anti-safety boiler that burns of bituminous coal

Technical field

The utility model belongs to the anti-safety boiler that burns of a kind of bituminous coal.

Background technology

Traditional heating boiler adopts directly burning type mostly, expend that coal, contaminated environment, volume are big, complex structure, get angry slow, heat utilization efficiency is low, cost of manufacture is high and price is expensive, and function of use is single, use and the stoking inconvenience, dust flies upward everywhere during deashing, contaminated environment, deashing are wasted time and energy, the grate structure complexity, be difficult for ash is removed, the burner hearth heat utilization efficiency reduced during deashing, and service life is short.In addition, for guarding against gas poisoning, do not allow to establish any closure that blocks in the new flue of heating boiler national standard requirement outside floss hole, and traditional heating boiler can not satisfy above-mentioned standard.

Summary of the invention

The purpose of this utility model is the anti-safety boiler that burns of a kind of bituminous coal of design, make it have the counter-burning type function, and province's coal is arranged, deashing and burning are free from environmental pollution, simple in structure, and cost of manufacture and price are low, quick combustion, safety in utilization is good, can effectively avoid gas poisoning, the advantage of heat utilization efficiency height and long service life.For this reason, the utility model adopts the water courage to be positioned at body of heater side and front and back stockhole periphery, delivery port communicates with the water courage that is positioned at the floss hole limit, furnace roof and front and back stockhole spacing distance are provided with, space between furnace roof and the front and back stockhole forms the furnace roof chamber, and the furnace roof chamber communicates with floss hole, and rear hearth mouth upper end is provided with the cigarette door that opens and closes space between furnace roof and the rear hearth mouth, the front furnace mouth is provided with capping, and the furnace roof of front furnace mouth upper end is provided with bell.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that and have the counter-burning type function, can save coal 50%, smokeless and dust emissions than traditional hot-water heating stove, free from environmental pollution, and volume is little, simple in structure, cost of manufacture and price is low, quick combustion, heat utilization efficiency highly improve 5%, higher security is arranged, can effectively avoid gas poisoning, and use stoking deashing is convenient and prolong 30% service life.

The specific embodiment

To shown in Figure 2, the anti-safety boiler that burns of a kind of bituminous coal is made up of body of heater 14, water courage 11, intake-outlet, rigid grate 16 and floss hole 6 as Fig. 1.The water courage is positioned at body of heater side and front and back stockhole periphery, and delivery port 8 communicates with the water courage that is positioned at the floss hole limit.Furnace roof 3 is provided with front and back stockhole spacing distance.Space between furnace roof and the front and back stockhole forms furnace roof chamber 1, and the furnace roof chamber communicates with floss hole.Rear hearth mouth 7 upper ends are provided with the cigarette door 5 that opens and closes space between furnace roof and the rear hearth mouth.Front furnace mouth 20 is provided with capping.The furnace roof of front furnace mouth upper end is provided with bell 2, and the rear hearth upper end is interval with several horizontal rows and puts water pipe 10 and one and tiltedly hang courage 9.

Described cigarette door upper end is provided with cigarette gate stop 4.The effect of cigarette gate stop is the convenient pulling cigarette door that opens and closes.Described cigarette door laterally slides and opens and closes the rear hearth mouth.The effect of cigarette door is to pass in and out air capacity in the burner hearth before and after the control.

Body of heater side and top and the seal clearance that adds between the layer 13 form the water courage.The in-furnace hanging chamber 21 that is positioned at the fire grate upper end is tilting, and the in-furnace hanging chamber bottom is sagging, is beneficial to make the coal spontaneous that inserts to form taper, is beneficial to coal tenesmus and burning.It is front furnace 20 and rear hearth 12 that in-furnace hanging chamber is cut apart the body of heater internal furnace.The infundibulate that rear hearth is big up and small down has the exhausting effect, is beneficial to the abundant burning of coal.Burner hearth lower end, front and back communicates, the coal that inserts from front furnace after the bell opened and the capping can only be for helping the auxilliary heat of penetrating coal-fired on the fire grate heat like this, the necessary downward high-temperature region of its fuel gas and dust through burner hearth lower end, front and back, could enter floss hole along the rear hearth mouth, thereby greatly reduce body of heater smoke evacuation dust quantity, and prolonged the body of heater endotherm area, increased substantially heat utilization efficiency.

Floss hole communicates on the rear hearth.Rear hearth upper end is interval with several horizontal rows and puts water pipe and one and tiltedly hang courage.Horizontal water pipe two ends and tiltedly hang the courage two ends and upper end and water courage and in-furnace hanging chamber intercommunication, every layer of horizontal water pipe is arranged in a crossed manner, is beneficial to every water pipe heat absorption evenly.Horizontal water pipe and tiltedly to hang courage tilting is beneficial to the water circulation.The rigid grate that is positioned at the rear hearth lower end is tilting.Fire grate is by rigid grate and reciprocating typely constituted from deashing fire grate 18.Back and forth, be existing structure, so be not repeated from the deashing fire grate.Rigid grate and be deashing chamber from deashing fire grate lower end back and forth, the body of heater of deashing chamber side is provided with shoot door 17, is beneficial to coal ash is removed deashing chamber.One wing furnace body of fire grate upper end is provided with side ort 19 and is used for deashing.During deashing, will hold the deashing handle and rock back and forth, and move forward and backward and shake, make back and forth that the coal ash on the deashing fire grate falls in the deashing chamber, finish deashing thereby drive back and forth from the deashing fire grate.Delivery port is positioned at and adds layer upper end, and phase water flowing courage top.Water inlet 15 phase water flowing courage bottoms.

During use, cold water enters water courage and horizontal water pipe, tiltedly hangs courage and in-furnace hanging chamber from water inlet, flows out body of heater to the radiator hot-water supply from delivery port again behind the burner hearth heat before and after absorbing.For the coal in the burner hearth is fully burnt and burning as early as possible, can all open the cigarette door, it is outdoor that the interior air of burner hearth directly enters the quick discharge of floss hole then, promptly produce the drawing fires effect, otherwise, catch on cigarette gate stop pulling cigarette door, sealing floss hole with poker, under the state of stockhole before and after the sealing, can control burning of coal speed in the burner hearth.Simultaneously, it is outdoor along floss hole and chimney discharge also not influence the coal gas that is positioned at the furnace roof chamber, can effectively avoid gas poisoning.

In a word, the utlity model has the counter-burning type function, and province's coal is arranged, deashing and burning are free from environmental pollution, Simple in structure, cost of manufacture and price are low, quick combustion, and safety in utilization is good, can effectively avoid gas poisoning, The advantage of heat utilization efficiency height and long service life. Can promote the use of.
