Description

Heating for multiple times power economized boiler

Technical field

The utility model is related to a kind of energy-saving stoves, i.e. a kind of power economized boiler suitable for room heat supply.

Background technology

The northern area of China winter temperature is relatively low, and room needs heat supply.City has been realized in heating station or large area Central heating, and live in more dispersed villages and small towns or warmed oneself using single household's dispersion.All using medium small boiler voluntarily Heat supply.The shell of this boiler is mostly double-layer water jacket, the cavity dress water between double-layer water jacket, and passes through outlet pipe and return pipe It is connected with warmer, forms circulation loop.What double-layer water jacket surrounded is to load the burner hearth that fuel burns, and has fire grate below burner hearth And ashpit, burner hearth top is equipped with smoke exhaust pipe, in flue gas emission to air.The heat that fuel combustion is released only is absorbed by furnace wall, Waste heat supply temperature after absorption is also very high or even is also discharged with flare, without it is secondary, absorb three times, heat waste is serious, no It is energy saving.This boiler thermal efficiency is very low.

There are also boilers currently on the market to increase heated walls that are secondary, absorbing heat three times, and these heated walls are vertical Arrangement, smoke exhaust pipe suction is inadequate, also needs to increase air-introduced machine, this consumes electric energy again.

In addition, in vast rural area, peasant will descend ground to work for a long time, since boiler does not have banking fire function, work as fuel It burns idle most, is not warmed up in room then gently, heavy then bursting by freezing heating.

Invention content

The purpose of this utility model be to provide it is a kind of be suitable for small-scale heat supply, can high multiple of long-time banking fire, the thermal efficiency Heating and energy saving boiler.

Above-mentioned purpose is realized by following technical scheme：A kind of heating for multiple times power economized boiler is developed, including furnace body, stove Thorax, fire grate, smoke exhaust pipe, its main feature is that：Furnace body is Double Layer Circular, and centre is water jacket, and water outlet, lower outside are equipped with outside upper end Equipped with water return outlet, furnace body internal upper part is equipped with multiple alternate heated walls staggeredly, is divided in the middle part of furnace body for burner hearth, burner hearth by fuel bulkhead Two cavitys are segmented into, one is burner hearth, another cavity is Bunker, and fire grate is equipped with below burner hearth, is ashpit below fire grate.

The heated walls are horizontally disposed, account for the 1/2-4/5 of inner circle area, and outer small interior big trapezoidal formula is hollow convenient for deashing And communicated with water jacket, the furnace body outer circle side opposite with heated walls is equipped with the shoot door of salable closing.

The fuel bulkhead forms semi-enclosed Bunker with furnace body inner surface, and Bunker top is equipped with salable closing Fuel door, the distance between fuel bulkhead lower face and fire grate are 120mm-200mm, and fuel bulkhead is hollow and and water jacket It communicates.

More heat pipes are equipped with above the burner hearth, burner hearth inferoanterior is equipped with fire door, and fire door is equipped with air inlet blind window.

The fire grate is circle, and forepart is fixed grate, opposite with Bunker, and rear portion is rotatable fire grate, with burner hearth phase It is right, a shaft is set among rotatable fire grate, is connected with the grey handle that falls on the outside of furnace body.

The front of the ashpit is equipped with ashpit door.

Smoke pipe valve is equipped in the smoke exhaust pipe.

The beneficial effects of the utility model are：Flue gas in the burner hearth complications in discharge pass through multiple heated walls, in flue gas Heat is fully absorbed, and the thermal efficiency significantly improves, and can long-time banking fire, have simple in structure, of low cost, the operation is stable, The advantages of safe and reliable.

Specific embodiment

The total design of the utility model is to provide a kind of small-scale indoor heating power economized boiler of heating for multiple times.It surrounds below This design combination attached drawing introduces a kind of embodiment：

Fig. 1, Fig. 2 introduce a kind of heating for multiple times power economized boiler, special including furnace body 1, burner hearth 19, fire grate 11, smoke exhaust pipe 9 Putting is：Furnace body 1 is Double Layer Circular, and centre is water jacket 15, water outlet 8 is equipped with outside upper end, lower outside is equipped with water return outlet 2, leads to It crosses water pipe with radiator to be connected, forms circulating heating system, 1 internal upper part of furnace body is equipped with multiple alternate heated walls 14 staggeredly, stove 1 middle part of body is burner hearth 19, and burner hearth 19 is divided into two cavitys by fuel bulkhead 12, and one is burner hearth 19, another cavity is fuel Storehouse 18,19 lower section of burner hearth are equipped with fire grate 11, and 11 lower section of fire grate is ashpit 21.

Heated walls 14 shown in Fig. 2 are horizontally disposed, account for the 1/2 to 4/5 of inner circle area, outer small interior big trapezoidal formula, it is hollow and It is communicated with water jacket, the furnace body 1 outer circle side opposite with heated walls 14 is equipped with the shoot door 7 of salable closing, and is locked by keeper 6 Extremely, the time is grown, and the 14 full coal ash of top product of heated walls opens shoot door 7, deashing is shoveled with stove at this time, since its surface is inclined-plane, Deashing is convenient.

The fuel bulkhead 12 forms semi-enclosed Bunker 18 with 1 inner surface of furnace body, and 18 top of Bunker is equipped with can be close The fuel door 5 closed is sealed, and is locked by keeper 6, the distance between 12 lower face of fuel bulkhead and fire grate 11 are 120mm- 200mm, fuel bulkhead 12 are hollow and are communicated with water jacket.When fuel burning in burner hearth 19, added in from fuel door 5 Fuel, since Bunker 18 is semiclosed, fuel only burner hearth 19 to fire grate 11 at burn, after having burnt, Bunker Fuel in 18 can be automatically replenished, and realize the purpose of long-time banking fire.The fuel be coal or granular fuel or Cow dung.

19 top of burner hearth is equipped with more heat pipes 13, expands heating surface area, improves the thermal efficiency.Before burner hearth 19 times Side is equipped with fire door 3, and fire door 3 is equipped with air inlet blind window 4, adjusts intake, controls furnace temperature.

Shown in Fig. 3, fire grate 11 is circle, and forepart is fixed grate, opposite with Bunker 18, and rear portion is rotatable fire grate, It is opposite with burner hearth 19, a shaft is set among rotatable fire grate, is connected with the grey handle 10 that falls in 1 outside of furnace body.It is hand to fall grey handle 10, dying embers can fall into ashpit 21.

The front of the ashpit 21 is equipped with ashpit door 20, the opening degree of control ashpit door 20, thus it is possible to vary 11 lower section of fire grate Intake, so as to change the size of the intensity of a fire in burner hearth 19.

Smoke pipe valve 16 is equipped in the smoke exhaust pipe 9, the valve is adjusted, changes the discharge of heat, at the same coordinate fire door 3 or into Air port blind window 4 and ashpit door 20 can reach the ideal banking fire time.

Label bracket 17 significantly is externally provided in 1 front of furnace body, product famous brand can be fixed on label bracket 17.

Experimental results demonstrate：The flue-gas temperature that this boiler is discharged from smoke exhaust pipe 9 is low, and the thermal efficiency is high, and energy-saving effect is notable, Can long-time banking fire can simultaneously start open fire at any time, of low cost without manpower frequent operation, and with simple in structure, work is steady Calmly, the advantages that safe and reliable, it is very suitable for the small-scale central heating demand in villages and small towns.Product famous brand can be fixed on label bracket 17 On.
