Abstract
The utility model relates to a multifunctional living half coal gas boiler, mainly comprising a boiler cylindrical shell, a boiler bladder, a convection heating surface, a coal burning storage hopper, a grate, a water-to-water heat exchanger, and a base. The utility model well solves the problems that coal has to be intermittently put into a vertical boiler with small capacity, and black smoke is easy to come out. The utility model has the advantages of convenient stoker working, high thermal efficiency, good effect of eliminating smoke and dust, and convenient manufacture. The utility model can well simultaneously supply institutions, schools, enterprises and institutions with heating, drinking water, steaming rice, and bathing.
Description
The utility model belongs to the Thermal Power Engineering technical field, the place that the zonule requires heating, drinking-water, steamed rice simultaneously and has a bath in being suitable for.
At present, be used for the multi-functional boiler for domestic that the zonule is satisfied heating, drinking-water, steamed rice simultaneously and had a bath, its combustion system mostly is double-layer grate semi-coal gas combustion system and fixed grate nature secondary wind semi-coal gas combustion system, and the former coal adaptability is poor, and the easy fouling of water-cooled grate tube causes booster; The latter, secondary air flow is wayward, and the heat loss due to exhaust gas height can only use lump coal.In addition, the binary heated face structure is adopted in the acquisition of multiple hot coal medium more, and consequently load is difficult for coordinating and coupling, influences the raising of the thermal efficiency.
The purpose of this utility model is for a kind of thermal efficiency height is provided to society, and smoke medicining dust-removing effect is good, and the stoker works easy, and labour intensity is low, and the boiler for domestic of multiple hot coal medium can be provided simultaneously.
The utility model is to be based upon on such basis of reality, independently coal-fired warehouse is set in the combustion chamber of boiler, its upper and lower opening communicates with secondary furnace and combustion chamber respectively, if the position of coal-fired warehouse, end opening size, shape are all reasonable, and can form suitable passage of flame, then can obtain the satisfied smoke effect and the stable intensity of a fire.
In order to reach this purpose, the utility model boiler is provided with coal-fired warehouse (6) in the combustion chamber of boiler, and it is suitable for reading to communicate with secondary furnace (12), and end opening is corresponding with fire grate (15), and provides red charcoal after dry, the destructive distillation for the combustion chamber.High-temperature flue gas that fuel combustion produces and flame enter in the secondary furnace (12) via passage of flame (7), and after-flame further burns.In upper boiler water capacity space, be provided with water-water heat exchanger (2) in addition, make it to be complementary with the thermal power of boiler.
Concrete enforcement of the present utility model is provided by accompanying drawing, and the contrast accompanying drawing describes in detail the utility model boiler below.
The utility model is mainly by boiler barrel shell (10), flue (11), and convection heating surface (3), coal-fired warehouse (6), fire grate (15), water-water heat exchanger (2), base (9) seven parts are formed.Boiler barrel shell (10), flue (11) adopts the garden tubular construction; Convection heating surface (3) forms 8 °～12 ° inclination angles, arranged crosswise with horizontal plane; Coal-fired warehouse (6) is applied simultaneously by several horizontal water tubes and smears refractory material (5) and form; It is placed in the combustion chamber, periphery is subjected to the radiation of the thermal-flame and the vehement hotbed of carbon, fuel is dried in coal-fired warehouse (6), fall on the fire grate (15) by deadweight after the destructive distillation, after-flame further burns, the fuel gas that destructive distillation is separated out, a part is passed down through red-hot charcoal grate firing to the greatest extent, after another part is upward through new coal and is cooled, mixes and the after-flame that burns with thermal-flame in secondary furnace (12); High-temperature flue gas and flame make progress horizontal wash away convection heating surface (3) after, enter atmosphere via exhaust opening (1) by chimney.When normal combustion, should fire coal be dropped in the coal-fired warehouse (6) from feeding door (13), feeding door (13) is closed, and shoot door (16) is opened, and when having only igniting and scarfing cinder, just opens clean-out door (14).
The water-water heat exchanger (2) that upper boiler water capacity space is provided with preferably adopts the spiral coil form, and its thermal power should be complementary with the thermal power of boiler, absorbs the heat content of boiled water in the boiler with equivalence, and satisfies the needs of heating to heat energy.
In order to cooperate the burning of fuel, improve the after-flame degree of fuel, in boiler combustion, be provided with adjustable primary air nozzle (8), simultaneously, adjustable overfiren air port (4) is set in secondary furnace (12).
Claims (7)
1, a kind of multi-functional semi-coal gas boiler for domestic mainly is made up of boiler barrel shell (10), flue (11), convection heating surface (3), coal-fired warehouse (6), fire grate (15), water-water heat exchanger (2), base (9) seven parts.It is characterized in that this seven part is constituted an integral body, by the burning of coal-firing efficient rate, heat energy conversion obtains multiple thermal medium.
2, multi-functional semi-coal gas boiler for domestic as claimed in claim 1 is characterized in that indoor being provided with of boiler combustion can be for the coal-fired warehouse (6) of coal-fired drying, destructive distillation.
3,, it is characterized in that the end opening of coal-fired warehouse (6) is corresponding with fire grate (15), for it provides red charcoal dry, destructive distillation continuously as the described multi-functional semi-coal gas boiler for domestic of claim 1 to 2.
4, as the described multi-functional semi-coal gas boiler for domestic of claim 1 to 3, it is characterized in that two mouthfuls of coal-fired warehouse (6) communicate with secondary furnace (12), the coal-fired part of separating out in coal-fired warehouse (6) inner drying, destructive distillation can be mixed gas and burn with thermal-flame.
5,, it is characterized in that coal-fired warehouse (6) is subjected to the radiation of the thermal-flame and the vehement hotbed of carbon in burner hearth as the described multi-functional semi-coal gas boiler for domestic of claim 1 to 4.
6, multi-functional semi-coal gas boiler for domestic as claimed in claim 1 is characterized in that combustion chamber and secondary furnace (12) cooperate, and rationally is provided with adjustable primary air nozzle (8) respectively, and overfiren air port (4).
