Abstract
Disclosed is a coal-fired hot air furnace, comprising a combustion chamber, a fire grate and an ash cavity; wherein, a smoke flue is arranged on the combustion chamber; a hot air cavity is formed by the combustion chamber and an outer side of the smoke flue enclosing a round drum; an air inlet, and an air blower to connect with a temperature control apparatus are arranged at the bottom of the hot air cavity; an air outlet is arranged on the upper of the hot air cavity; the side wall of the combustion chamber is communicated with an air duct; an air inlet hole is arranged on the air duct; a convex hot air cavity is arranged at the air inlet of the middle and upper of the combustion chamber; the smoke flue is composed of alternant thick drums and thin drums; a plurality of heat dissipating fins are arranged at the outer side of the combustion chamber and the smoke flue. The utility model has the advantages of good heat dissipating effect, fast rising temperature, high heat efficiency and low pollution, and thus is an ideal coal-fired hot air furnace used for the heating of residences, greenhouses and barns.
Description
Technical field
The utility model relates to a kind of hot-blast stove, is specifically related to a kind of coal-fired hot-blast stove that is used for heatings such as dwelling house, greenhouse, booth.
Background technology
Hot-blast stove has and heats fast, thermal efficiency advantages of higher and use gradually in beginnings such as north of china in winter dwelling house, greenhouse, booths, present hot-blast stove majority exists hot blast chamber and Combustion chamber design unreasonable, radiating effect is poor, the thermal efficiency is low, fire coal can not fully burn, waste fuel, flue gas is bigger, the shortcoming of contaminated environment.
Summary of the invention
The purpose of this utility model is to provide a kind of good heat dissipation effect, heats soon the high oligosaprobic coal-fired hot-blast stove of the thermal efficiency.
Coal-fired hot-blast stove of the present utility model, comprise the combustion chamber, fire grate is installed below the combustion chamber, grey chamber and air door are arranged below the fire grate, flue is arranged on the combustion chamber, the outside of combustion chamber and flue surrounds cylinder and constitutes the hot blast chamber, air inlet and hair-dryer are arranged at the bottom in hot blast chamber, air outlet is arranged at top, its structural feature is: side wall of combustion chamber has the ventilating duct in logical grey chamber, and the fresh air inlet of some logical combustion chambers is arranged on the ventilating duct, and there is the protruding hot blast chamber of advancing at the air inlet place, middle and upper part of combustion chamber, described flue is made up of thick tube that replaces and thin tube, in the outside of combustion chamber and flue some fin is arranged.
Stagger and be communicated with thick between the thin tube of the levels of described flue.
Described hair-dryer is connected with attemperating unit, and this attemperating unit is included in the temperature sensor of air outlet, control circuit, relay, temperature display device and gauge tap.
Advantage of the present utility model is: because there is the protruding hot blast chamber of advancing at air inlet place, middle and upper part, combustion chamber, flue is made up of thick tube that replaces and thin tube, and there are some fin in the outside of combustion chamber and flue, and wind chamber exchanged heat area is big, and air heats soon, thermal efficiency height.Side wall of combustion chamber has the ventilating duct in logical grey chamber, and the fresh air inlet of some logical combustion chambers is arranged on the ventilating duct, can realize that secondary gives wind, improves the coal-fired thermal efficiency, reduces smoke pollution.
Further advantage of the present utility model is: because hair-dryer is controlled by attemperating unit, just start hair-dryer when the hot blast cavity temperature reach a certain height, continue blowing waste electric energy when wind and the furnace temperature of blowing on when having avoided cooking stove just to light a fire reduction or blowing out.
