Abstract
The utility model relates to hot air central heating equipment, in particular to a coal-fired hot blast furnace, which comprises a furnace body. A heat exchanging device is arranged in a furnace cavity of the furnace body, a combustion chamber is arranged on the lower portion of the furnace body, a fume dust catcher is connected to a tail gas outlet in the middle of the furnace body, a hot air outlet is arranged on the side wall of the combustion chamber, a secondary air inlet connected with an air blower is arranged on the top of the furnace body. The coal-fired hot blast furnace is sufficient in air supply, combustion is complete, the waste problem caused by incomplete combustion is radically resolved, and cost is reduced. Furthermore, the coal-fired hot blast furnace is compact in structure, reasonable in arrangement, high in heat exchanging intensity, quick in temperature rising, high in heat efficiency, small in occupied area, convenient in mounting and operation, clean in hot air, stable in performance and the like.
Description
Technical field
The utility model relates to a kind of hot-air central heating equipment, relates in particular to a kind of coal-fired hot-blast stove.
Background technology
Hot-blast stove is widely used in oven dry, spraying, the dehydration of various materials such as chemical industry, food, medicinal material, tobacco, pottery, building materials.The dehumidifying or the temperature-rise period that also can be used for places such as the heating of building such as factory building, auditorium, agricultural canopy, animal house and underground mining area, underground engineering.
Can there be the air feed deficiency in existing hot-blast stove mostly, causes the inadequate defective of fuel combustion, thereby causes wasting resource, has also increased cost.
The utility model content
The utility model is in order to make full combustion of fuel, a kind of coal-fired hot-blast stove is provided, comprise body of heater, be provided with heat-exchanger rig in the furnace chamber of body of heater, the body of heater bottom is the combustion chamber, and the tail gas exit at body of heater middle part is connected with smoke duster, and side wall of combustion chamber offers hot-blast outlet, the body of heater top offers the secondary air inlet mouth, and described secondary air inlet mouth is connected with air blast.
The beneficial effects of the utility model are, because the utility model coal-fired hot-blast stove air feed abundance, sufficient combustion has solved the waste problem that fuel causes not to the utmost because of burning at all, reduced cost, and the utility model compact conformation, rationally distributed, heat transfer intensity is big, quick heating, thermal efficiency height, have that floor space is little, fitting operation is convenient, hot blast is clean, characteristics such as stable performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a kind of coal-fired hot-blast stove most preferred embodiment of the utility model.
Among the figure: 1, body of heater, the outlet of 1-1, tail gas, 1-2, secondary air inlet mouth, 2, the combustion chamber, 2-2, hot-blast outlet, 3, smoke duster, 4, air blast.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of coal-fired hot-blast stove as shown in Figure 1, comprise body of heater 1, be provided with heat-exchanger rig in the furnace chamber of body of heater 1, body of heater 1 bottom is combustion chamber 2, and the tail gas outlet 1-1 place at body of heater 1 middle part is connected with smoke duster 3, and the sidewall of combustion chamber 2 offers hot-blast outlet 2-1, body of heater 1 top offers secondary air inlet mouth 1-2, secondary air inlet mouth 1-2 is connected with air blast 4, can be so that the air inlet abundance, and sufficient combustion.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
