Abstract
The utility model discloses a heating furnace which belongs to the technical field of heating equipment. The utility model is composed of a heating furnace body, a discharge flue and a water preheating device, wherein the water preheating device is fixed at the lower end of the discharge flue; a water outlet of the water preheating device is connected with a water inlet on the heating furnace body; a furnace grill is arranged at the lower surface of the inner wall of the heating furnace body and fixed on a casing; a spiral coil is inserted in the inner wall of the heating furnace body; a pipe coil is fixed in the inner cavity of the water preheating device. In the heating furnace with the structure, feedback water passes through the pipe coil of the water preheating device to reduce the temperature of smoke in the discharge flue; after preheated in an air inlet passage and a cavity, cold air enters the cavity of the furnace body through the furnace grill; so the heat radiation loss of the heating furnace body is reduced, the water circulation speed of the main heating surface of the heating furnace body is accelerated, the heat-exchange rate is increased, the temperature of output water is increased, the cost is low, the energy is saved and the installation and the operation are convenient.
Description
Technical field
The utility model has separated a kind of novel heating stove, belongs to the heating equipment field.
Background technology
In northern China, after arriving the winter of severe cold, resident family etc. generally all adopts heating stove to improve room temperature and resists severe cold.But the heating stove thermal efficiency on the market is very low, generally has only about 60%.In recent years, heating equipment manufacturer constantly increases the body of heater volume in order to improve heat flux, enlarges heat exchange area, and this has increased the consumption and the manufacturing cost of metal material virtually, and simultaneously, the consumption of coal also increases greatly, and the thermal efficiency descends on the contrary as a result.The waste heat that utilizes flue that has carries out post bake to the water after the heating of heating body of heater, and this makes the waste heat of flue can not get good utilization.The too slow rate of heat exchange of the flowing velocity of heating body of heater master hot side place water is low, and the heat radiation of heating body of heater fails to be fully used.
Technology contents
The utility model discloses a kind of cost low, improve heat absorption efficient, energy savings, easy to install, utilize smoke discharging residual heat to give the novel heating stove of feedback water preheat.
The utility model is achieved through the following technical solutions:
A kind of novel heating stove, form by heating body of heater, smokejack and water pre-heater apparatus, water pre-heater apparatus is fixed on the lower end of smokejack, the delivery port of water pre-heater apparatus links to each other with water inlet on the heating body of heater, fire grate is below the inwall of heating body, and be fixed on the shell, inlay spiral coil in the inwall of heating body of heater, be fixed with coiled pipe in the inner chamber of water pre-heater apparatus.
One cavity is arranged between the inwall of described heating body of heater and the shell, have the air entrance driveway to link to each other with cavity between the stone or metal plate for standing a stove on as a precaution against fire of the upper end of shell and heating body of heater, the lower end of cavity is a fire grate.
The inner surface of the inwall of described heating body of heater is a heat-absorbing material, and outer surface is a heat-barrier material.
Coiled pipe in the described water pre-heater apparatus is at least one.
Described spiral coil is at least one.
Adopt the heating stove of said structure, feedback water is through the coiled pipe of water pre-heater apparatus, reduced cigarette temperature in the smokejack, cold air by air intlet road, cavity preheating after, enter in the body of heater chamber by fire grate, this has reduced the radiation loss of heating body of heater, accelerated the water circulating speed at heating body of heater master hot side place, improved rate of heat exchange, improved the temperature of output water, cost is low, energy savings, easy to install.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is three spiral coil structural representations of the present utility model.
Fig. 3 is a scheme of installation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the water inlet 7 that the feedback water that returns from radiator is introduced into water pre-heater apparatus 2 enters coiled pipe 5, carry out heat exchange with flue gas here, reduced the temperature of cigarette in the smokejack 3, the water that flows out from the delivery port 4 of water pre-heater apparatus 2 enters heating body of heater water inlet 15, enter radiator through spiral coil 13 and heating body of heater delivery port 9, adopting spiral coil is in order to have increased the contact area of heat exchange, reduced the flow area area of water, this just improves rate of heat exchange, cold air is entered in the cavity 11 that is surrounded by shell 10 and heating inboard wall of furnace body 12 by the shell 10 and the air intlet road 6 between the stone or metal plate for standing a stove on as a precaution against fire 8 of heating body of heater, after the heat that sheds with the heating body of heater exchanges preheating, enter in the body of heater chamber 14 by fire grate 16, this has reduced the radiation loss of heating body of heater, increase the temperature of air in the burner hearth simultaneously, saved the energy.
With reference to Fig. 3, the feedback water that returns from radiator is introduced into water pre-heater apparatus 2, carries out entering after the heat exchange again and carries out heat exchange in the body of heater 1, this has accelerated the water circulating speed at body of heater master hot side place, improved rate of heat exchange, improved the temperature of output water, cost is low, energy savings, easy to install.
Claims (5)
1, a kind of novel heating stove, form by heating body of heater, smokejack and water pre-heater apparatus, water pre-heater apparatus is fixed on the lower end of smokejack, the delivery port of water pre-heater apparatus links to each other with water inlet on the heating body of heater, fire grate is below the inwall of heating body, and be fixed on the shell, it is characterized in that: inlay spiral coil in the inwall of heating body of heater, intrinsic coiled pipe in the inner chamber of water pre-heater apparatus.
