Description
Technical field
The utility model belongs to the coal-burning boiler technical field, relates in particular to a kind of pressure-bearing, normal pressure series of heat homogeneous solution-type reactor, particularly a kind ofly changes the direct combustion coal burning boiler into coal and changes the Gas boiler that gas burns.
Background technology
Present domestic heating equipment is based on boiler, and traditional boiler oil is mainly with coal, because environmental protection requirement adopts fuel oil or gas fired-boiler in recent years.Though fuel oil or gas fired-boiler soot emissions have reached environmental requirement, the operating cost costliness, the user is difficult to bear.The form of coal-burning boiler is more, but because the direct combustion fumes exhaust emission environment of coal can't reach environmental requirement.Boiler exists burning insufficient, cost height, contaminated environment, shortcomings such as operation inconvenience.
The utility model content
The purpose of this utility model is the weak point at above-mentioned prior art, coal direct combustion burning boiler wastes energy in the prior art in order to solve, contaminated environment for satisfying the requirement of environmental protection and energy saving, is that fuel self can produce coal commentaries on classics gas heating boiler with the coal for the urban life heating provides a kind of employing.
The utility model adopts following technical scheme to realize: this coal-turned-gas boiler mainly comprises the basis, base, charge door, tertiary air orifice, overfiren air port and an air compartment, blower fan, it is characterized in that: be provided with vaporizer in this coal-turned-gas boiler, the centre of combustion chamber is provided with leading heated brickwork, heat conduction furnace wall after the centre of combustion chamber and Heat Room is provided with ramp type, its underpart is the air cavity that communicates with each other, upside at leading heated brickwork is provided with gas exit, air compartment is set one time in the bottom of combustion chamber, bottom at described leading heated brickwork is provided with inclined grate, its upper end links to each other with the vaporizer furnace wall, coal-pushing plate is set on fire grate, top at vaporizer and combustion chamber and Heat Room is a upper drum, the bottom is the lower drum that the next part case connects, and the afterbody of air-exchanging chamber is provided with exhanst gas outlet.
Boiler profile described in the utility model be horizontal, vertical be main.
The utility model is compared advantage with prior art: because the coal in the vaporizer is lighted under the cooperation of a wind, carbon monoxide that the initial stage temperature produces when low and carbon black are main coal gas, secondly the secondary wind from the vaporizer top makes coal gas that strong stirring take place, in vaporizer, produce eddy current, prolong coal gas and coal dust burning time in vaporizer, strengthened coal gas and Air mixing combustion efficiency.Volatile matter discharges the later stage in the vaporizer coal, along with temperature raises, has discharged the unburnt coal cinder of volatile matter and has been pushed on the fire grate of bottom, combustion chamber.Become flexible coking coal or add new coal, its interior volatile matter is fully discharged, reduced the vaporizer temperature simultaneously, and, prevented that acid gas from producing without coolings such as steam.
The wind of described tertiary air orifice from the gas exit setting enters under combustion chamber and the acting in conjunction from a wind of fire grate, the coal gas of combustion chamber is fully burnt, thereby realized the most charcoal of coal gas and unburned in the combustion chamber synchronous high-temp combustion, the hot flue gas that produces in the combustion chamber directly enters Heat Room and carries out heat exchange, thermal efficiency height, simple in structure easy to operate, operating cost is low, pollution-free, the characteristics of environmental protection and energy saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the coal-turned-gas boiler structural representation.
The specific embodiment
With reference to shown in Figure 1, among the figure: 1 coal filling hole, 2 vaporizers, 3 overfiren air ports, 4 upper drums, 5 leading heated brickworks, 6 gas exits, 7 tertiary air orifices, 8 combustion chambers, 9 back heat conduction furnace walls, 10 Heat Rooms, 11 hot water outlets, 12 exhanst gas outlets, 13 water-cooling pipes, 14 lower drums, 15 water inlets, 16 blower fans, 17 bases, 18 bases, 19 air compartments, 20 air compartments, 21 fire grates, 22 coal-pushing plates, 23 fire doors.Coal-turned-gas boiler of the present utility model, mainly comprise basis 18, base 17, charge door 1, tertiary air orifice 7, overfiren air port 3 and air compartment 20 blower fans 16 is characterized in that: the centre that is provided with vaporizer 2 combustion chambers 8 in this coal-turned-gas boiler is provided with leading heated brickwork 5, heat conduction furnace wall 9 after the centre of combustion chamber 8 and Heat Room 10 is provided with ramp type, its underpart is the air cavity that communicates with each other, upside at leading heated brickwork 5 is provided with gas exit 6, in the combustion chamber 8 the bottom air compartment 19 is set one time, in the bottom of leading heated brickwork 5 inclined grate 21 is set, its upper end links to each other with vaporizer 2 furnace walls, coal-pushing plate 22 is set on fire grate 21, top at vaporizer 2 and combustion chamber 8 and Heat Room 10 is a upper drum 4, the bottom is the lower drum 14 that the next part case connects, and the afterbody of air-exchanging chamber is provided with exhanst gas outlet.
From Fig. 1 as seen, from charge door 1 coal is added on the vaporizer 2 bottom fire grates 21, lead to wind ignition through an air compartment 20 to its vaporizer 2, initial stage produces the coal gas based on carbon monoxide and carbon black, under next secondary wind action from the overfiren air port 3 at vaporizer 2 tops, the coal gas that gas is given birth to enters in the combustion chamber 8 and discharges not the phase temperature from the volatile matter in the tertiary air mixing high-temp combustion later stage vaporizer 2 of three air distribution outlets 7 up to more than 1000C ° through gas exit 6, shift the uncombusted coal cinder of the fire grate 21 of vaporizer 2 bottoms onto combustion chamber 8 with coal-pushing plate 22, on the fire grate 21 of bottom with the wind action of sending here from air compartment under, after-flame at high temperature burns away, thereby realized that coal gas and the synchronous high temperature of unburnt carbon burn in combustion chamber 8, the hot flue gas that produces through burning directly enters Heat Room 10 heat exchange through air cavity, flue gas after the heat exchange discharges out of the furnace through exhanst gas outlet 12, and ash content and slag fall in the pond of its underpart.
