Abstract
The utility model relates to a boiler, in particular to a warm air furnace, which comprises a furnace body provided with a feeding coal port and an ash outlet at the lower part. A chimney interface is arranged at the upper part of the furnace body. A grate is arranged between the feeding coal port and the ash outlet in a chamber of a furnace body, and the utility model is characterized in that the furnace body is composed of a shell and an inner sleeve and form a hollow cavity interlayer, and a plurality of uniform heating pipes are arranged on the inner wall along the axial direction of the inner sleeve; both ends of the heating pipes are fixed and connected with the inner wall of the inner sleeve and are communicated with the hollow cavity interlayer respectively, the lateral wall of the furnace body, which is close to the top, is provided with an hot air exit communicated with the hollow cavity interlayer. The boiler has the advantages of high heat efficiency, quick temperature rise and small coal consumption, is especially suitable for the heating of rural big sheds and feeding sheds and can meet requirements of the temperature rise of long distance or the temperature rise of short distance.
Description
Technical field
The utility model belongs to boiler, relates in particular to the hot-blast stove of a kind of thermal efficiency height, energy-saving and environmental protection.
Background technology
At present, the vertical boiler structure of selling on the market is that the wall cover is built heat-insulation layer formation burner hearth in body of heater substantially, coal places on the fire grate, and it is indoor or be provided with water jacket samdwich in furnace body wall that heat is passed to heating by chimney, and water heating back is wherein passed in the radiator by pipeline.The boiler thermal output of this structure is low, intensification is slow, coal consumption is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of hot-blast stove is provided, and this kind boiler thermal output height, quick heating, coal consumption are little, is particularly useful for the rural area booth, raises the heating of canopy.
The utility model for achieving the above object, by the following technical solutions: a kind of hot-blast stove, being included in the bottom is provided with the mouth of delivering coal, the body of heater of ash hole, upper of furnace body and is provided with the chimney interface, deliver coal and be provided with fire grate between mouth, the ash hole in body of heater thorax inherence, it is characterized in that: described body of heater is made up of shell and interior cover and is formed the cavity interlayer, be provided with some uniform heating tubes along the axial inwall of interior cover, the heating tube two ends are fixedly connected with interior cover inwall respectively and communicate with the cavity interlayer, and sidewall of the furnace body is provided with the hot-blast outlet that is communicated with the cavity interlayer near the top.
Corresponding fire grate position, described body of heater bottom is provided with the air outlet that is communicated with the cavity interlayer and air blast is installed, and air outlet is provided with bypass and leads to the fire grate bottom by combustion-supporting airduct.
Be provided with dividing plate in the described cavity interlayer circumferential side wall.
Described hot-blast outlet is provided with can change doubling formula air door.
Described heating tube adopts cast iron materials to make.
Described body of heater inner chamber adopts cast iron materials to make.
The beneficial effects of the utility model: this kind boiler thermal output height, quick heating, coal consumption are little, are particularly useful for the rural area booth, raise the heating of canopy.Can satisfy the requirement that remote intensification or short distance heat up.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of hot-blast stove, be included in the bottom be provided with band fire door 2 deliver coal mouthfuls 3, the body of heater 1 of ash hole 4, upper of furnace body be provided with the chimney (not shown) that chimney interface 5 connects to outdoor extension, deliver coal and be provided with fire grate 6 between mouth, the ash hole in body of heater thorax inherence, described body of heater is made up of shell 1-1 and interior cover 1-2 and is formed cavity interlayer 7, be provided with some uniform heating tubes 8 along the axial inwall of interior cover, the heating tube two ends are fixedly connected with interior cover inwall respectively and communicate with the cavity interlayer, and sidewall of the furnace body is provided with the hot-blast outlet 9 that is communicated with the cavity interlayer near the top.Corresponding fire grate position, described body of heater bottom is provided with the air outlet 10 that is communicated with the cavity interlayer and passes through connecting pipe 15 air blasts 11 are installed, and air outlet is provided with bypass and leads to the fire grate bottom by combustion-supporting airduct 12, can send oxygen and aiding combustion to coal combustion.Be provided with prefabricated dividing plate 13 in the described cavity interlayer circumferential side wall, dividing plate places position between innermost layer and the short heating tube two ends.Dividing plate directly blows on the heating tube of heat temperature raising in order to guarantee new wind that air blast send, hot blast is sent by hot-blast outlet again, and is avoided air blast by the cavity interlayer cold wind directly to be sent in the heating tube, lowers efficiency.Described hot-blast outlet is provided with can change doubling formula air door 14, by changing the air-supply area of section, improves wind speed, has reached to adjust far and near distance conveying warm braw speed, when needs long distance warm braw, air door is rotated half, and hot-blast outlet only stays half air-out; When sending warm braw air door is all opened whole hot-blast outlet air-out if need short distance to heat up.Described heating tube and body of heater inner chamber all adopt cast iron materials to make, and are applicable to that air does the heating tube dry combustion method of medium, can anti-ly burn.Directly to the heating tube heating, make its quick heating by coal combustion, again the temperature Centralized of heating tube is delivered to heating system by hot-blast outlet, make full use of the heat of coal combustion, the efficient of boiler is improved.
Embodiment
The body of heater height: 1.7 meters, body of heater external diameter: 70CM, the fire grate height: apart from 0.3 meter of bottom, heating tube quantity: 8 of long tubes, 15 of short tubes.Air blast adopts centrifugal fan (model: 472-3.6)
The above only is the preferred embodiment of hot-blast stove, is not the structure of hot-blast stove is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
