Abstract

The utility model discloses a fire coal reverse combustion multi-return environmentally-friendly hot-water boiler. A furnace body is provided with a jacket hearth; an ash residue chamber is formed below a circular pipe fire grate below a reverse combustion hearth below the inner front side of the furnace body; a lower fire grate is arranged below the ash residue chamber; a row pipe and a jacket baffle plate communicated with the jacket furnace wall are arranged on the inner back side of and above the furnace body; a smoke exhaust hole is formed above a convective flow heat exchange device in the furnace body; a vertical threaded smoke pipe is arranged in the back wall of the jacket furnace wall; a lower smoke box is arranged below the back wall of the jacket furnace wall; the upper pipe orifice of the threaded smoke pipe is communicated with the smoke exhaust hole above the furnace body; the lower pipe orifice of the threaded smoke pipe is communicated with the lower smoke box; and the lower smoke box is provided with a smoke outlet. The threaded smoke pipe is arranged in the back wall of the jacket furnace wall, so that heat in flue gas can be recovered effectively, and the heat efficiency of the boiler is high. The threaded smoke pipe has large heat transfer amount, contributes to saving steel and reducing cost, and has a self-cleaning function. When a new fuel starts forming burnt red coal on a residue layer of the circular pipe fire grate, the fuel falls onto a lower layer fire grate for burning continually, so that the fuel burns completely, and the coal consumption is lowered.

Description

Coal-fired anti-many backhauls environment protecting water-heating boiler that burns
Technical field
The present invention relates to the anti-burning water-heating boiler of a kind of fire coal, the heat convection device of the anti-burning water-heating boiler of particularly a kind of fire coal.
Background technology
Characteristics such as the efficiency of combustion that coal-fired anti-burning water-heating boiler has fuel is high, and the smoke evacuation dust is low are called as environment-protection boiler.In the prior art, disclose the anti-burning water-heating boiler of a kind of fire coal among the Chinese patent ZL 2,005 2 0092920.7, the anti-burning water-heating boiler of this fire coal has vertical cuboid body of heater; Body of heater has the chuck furnace wall, and there is delivery port the top of chuck furnace wall, and there is water inlet the below of chuck furnace wall; There is anti-burning burner hearth below, front side in the body of heater, and the anti-burner hearth that burns has the chuck hearth wall that communicates with the chuck furnace wall, and there is the pipe fire grate that communicates with chuck furnace wall and chuck hearth wall the below of chuck burner hearth; There is cinder chamber the below of pipe fire grate; The anti-antetheca that burns burner hearth has fire door, and the antetheca of cinder chamber has the lime-ash door, and there is the heat convection device rear side and top in the body of heater; The heat convection device has tubulation and the deflection plate that communicates with the chuck furnace wall; There is exhaust opening the top of heat convection device in the body of heater, and anti-front side of burning burner hearth is the air port once, and there is overfiren air port the front side of cinder chamber.
During use; In chuck furnace wall, chuck hearth wall and the pipe fire grate of the anti-burning water-heating boiler of fire coal, add water continuously from water inlet, let coal on the anti-pipe fire grate that burns in the burner hearth, burn, the high-temperature flue gas of generation gets between the tubulation pipe of heat convection device; Upwards and after three flow processs being folded to of level discharge from exhaust opening; The heat chuck hearth wall that coal combustion produces, the water in pipe fire grate and the chuck furnace wall, hot water can be discharged heat supply continuously from delivery port.
The anti-burning water-heating boiler of this fire coal has following deficiency:
1. in the heat convection device, water is walked in the pipe, and high-temperature flue is made leave with rage between pipe; The flow velocity of high-temperature flue gas is lower, and heat transfer coefficient is less, behind the heat convection; The flue gas of discharging from exhaust opening also has certain heat, causes exhaust gas temperature high, and heat utilization ratio is low, the thermal efficiency of boiler is not very high;
2. the anti-burner hearth that burns has only one deck fire grate, and when coal burnt on fire grate, some unburnt coal can fall down from fire grate, drops to cinder chamber, lacks burning condition in cinder chamber, causes fuel availability low.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, it is higher to propose a kind of fuel availability, coal-fired anti-many backhauls environment protecting water-heating boiler that burns that the thermal efficiency of boiler is higher.
The present invention realizes with following method.
Coal-fired anti-many backhauls environment protecting water-heating boiler that burns has vertical cuboid body of heater, and body of heater has the chuck furnace wall, and there is delivery port the top of chuck furnace wall; There is water inlet the below of chuck furnace wall, and there is anti-burning burner hearth the below, front side in the body of heater, and the anti-burner hearth that burns has the chuck hearth wall that communicates with the chuck furnace wall; There is the pipe fire grate that communicates with chuck furnace wall and chuck hearth wall the below of chuck burner hearth, and there is cinder chamber the below of pipe fire grate, and the anti-antetheca that burns burner hearth has fire door; The antetheca of cinder chamber has the lime-ash door, and there is the heat convection device rear side and top in the body of heater, and the heat convection device has tubulation and the chuck deflection plate that communicates with the chuck furnace wall; There is exhaust opening the top of heat convection device in the body of heater, and anti-front side of burning burner hearth is the air port once, and there is overfiren air port the front side of cinder chamber; Vertical threaded flue is arranged in the rear wall of chuck furnace wall, and there is lower smoke box the rear wall below of chuck furnace wall, and the upper orifice of smoke pipe communicates with the exhaust opening of body of heater top; The lower nozzle of threaded flue communicates with lower smoke box, and lower smoke box has outlet flue and breast hole, and there is lower fire grating the below of cinder chamber; There is following cinder chamber the below of following furnace wall, and there is following lime-ash door in following cinder chamber.
In the rear wall of chuck of the present invention furnace wall vertical threaded flue is arranged; Discharge from outlet flue through behind the threaded flue from the flue gas that exhaust opening is discharged; Flue gas is that rotation is flowed in threaded flue, the rapid speed of air-flow, and heat transfer coefficient is bigger; Can reclaim the heat in the flue gas of discharging from exhaust opening, improve the thermal efficiency of boiler.The heat output of threaded flue is equivalent to 1.7 ~ 1.8 times of straight smoke pipe; Adopt threaded flue quantity obviously to reduce than the straight smoke pipe quantity of employing; Make boiler practice thrift steel, reduce manufacturing cost, threaded flue has " cleaning certainly " effect to dry and soft cigarette ash; Under normal operating condition, the dust stratification in the threaded flue is than straight smoke pipe much less.
There is two-layer fire grate anti-burning burner hearth of the present invention below, and upper strata pipe fire grate is the main chamber fire grate, during operate as normal; Only to upper strata pipe fire grate upslide coal, fresh fuel on the pipe fire grate of upper strata through processes such as the effusion of preheating, drying, volatile matter, ignition, when the slag blanket of pipe fire grate begins to form spent anthracite; Anthracite is along with volume-diminished or poke fire; Left out by mistake on lower floor's fire grate and can be burnt away by the gap of upper strata pipe fire grate, fuel combustion is abundant, reduces coal consumption.
Below in conjunction with accompanying drawing, the present invention is done explanation further.
