Description
Technical field:
The present invention relates to a kind of moulded coal normal-pressure boiler, especially a kind of heating surface area is big, heat utilization ratio is high, heat transfer speed is fast, save coal-fired reheated energy-saving coal atmospheric pressure boiler.
Background technology:
At present, for reducing environmental pollution, what generally promote the use of is molded coal boiler.The structure of molded coal boiler is that body of heater is arranged mostly, space in the body of heater forms burner hearth, ventilating opening (fire grate), ashes chamber and fire door are arranged under the burner hearth, be connected to exhaust opening with burner hearth, in the upper end of body of heater the moulded coal dispensing port is arranged, the burner hearth top is provided with the water pipe that crawls and arrange, and is connected to water return outlet, hot water outlet with water pipe.During use, by the moulded coal dispensing port moulded coal is placed in the burner hearth, cover bell, the flue gas (heat) that the moulded coal burning is produced heats water pipe, hot water in the water pipe flows out from hot water outlet and enters heating system heat radiations such as (steam heating pipe, radiators) after water return outlet is got back to burner hearth heating, circulation repeatedly.Because the space in the body of heater is limited, make that the coil that participates in heat exchange is few, cause heating surface area little, thermal conversion efficiency is low.In order to increase heating surface area, the body of heater that has adopts the double-layer furnace body that communicates with the burner hearth inner conduit, makes heat that moulded coal produces except that water pipe is heated, and also the water in the double-layer furnace body is heated; The water pipe with in the burner hearth that also has is designed to be coiled in helix tube on the burner hearth sidewall.But because the burner hearth of existing boiler is direct and exhaust opening joins, the flue gas that is produced is directly emitted, and exists following problem:
1. heat utilization ratio is low, makes heating surface area less relatively, desires the heating effect that reaches desirable, and a large amount of fire coal of essential burning exists the phenomenon that wastes energy;
2. from the flue gas that exhaust opening is discharged, also contain very high heat, temperature is about 600～800 ℃, the chimney that must use exotic material (cement, pottery, iron etc.) to make, price height not only, and its life-span can reduce greatly because of the high-temperature flue gas calcination, installation cost, the maintenance cost of boiler are bigger.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, the reheated energy-saving coal atmospheric pressure boiler that a kind of heating surface area is big, heat utilization ratio is high, heat transfer speed is fast, saving is coal-fired to be provided.
Technical solution of the present invention is: a kind of reheated energy-saving coal atmospheric pressure boiler, double-layer furnace body 1 is arranged, and burner hearth 2 is arranged in the double-layer furnace body 1, air vent 3, ashes chamber 4 and fire door 5 are arranged below the burner hearth 2, be connected to exhaust opening 6 with burner hearth 2; There is moulded coal dispensing port 7 upper end of double-layer furnace body 1, bell 8 is arranged on the moulded coal dispensing port 7, be connected to water return outlet 9, hot water outlet 10 with double-layer furnace body 1, constitute flue 11 between described burner hearth 2 outer walls and double-layer furnace body 1 inwall, in flue 11, be provided with the helix tube 12 of coiling burner hearth 2 outer walls, helix tube 12 tangentially is connected to import 13, outlet 14 with double-layer furnace body 1, and burner hearth 2 communicates with exhaust opening 6 by flue 11.
Also be provided with external furnace body 15 outside double-layer furnace body 1, constitute flue 16 between double-layer furnace body 1 outer wall and external furnace body 15 inwalls, flue 11 communicates with exhaust opening 6 by flue 16, and exhaust opening 6 is positioned at the upper end of flue 16.
Described water return outlet 9 and hot water outlet 10 differ in the horizontal direction 180 degree and water return outlet 9 in the lower end, hot water outlet 10 is in the upper end.
9 places are provided with the backwater racecourse bend 17 that places in the double-layer furnace body 1 at described water return outlet.
Described helix tube 12 is different inside and outside two of screw diameter, and every all has import 13,14, two imports 13 of outlet of tangentially joining with double-layer furnace body 1 to differ 180 degree in the horizontal direction, and two outlets 14 differ 180 degree in the horizontal direction.
Described burner hearth 2 upper ends are provided with radiation heat insulation lid 18.
Described flue 11 lower ends are provided with the condensed water port 19 that communicates with flue 16.
Described burner hearth 2 is built-in with the moulded coal ring washer 20 that is complementary with type coal shape.
The present invention places burner hearth in the body of heater, form flue between hearth outer wall and the inboard wall of furnace body, burner hearth joins by flue and exhaust opening, the not only heating of the water in helix tube in burner hearth of the flue gas that moulded coal burning back produces, and in flue, the water in the helix tube is heated (re-heat) once more, also the water in the double-layer furnace body is heated simultaneously.Compare with prior art, have following advantage:
1. made full use of the heat of flue gas, heating surface area is big, good effect of heat exchange, and available less fire coal reaches desirable heating effect, saves a large amount of energy;
2. owing to the heat in the flue gas is fully utilized, after-heat is lower from the flue gas that exhaust opening is discharged, temperature is not higher than 70 ℃, need not to use exotic material, as long as make chimney with low price, corrosion resistant plastics, prolong the service life of chimney greatly, reduced the installation cost and the maintenance cost of boiler;
3. external furnace body and the formed flue of double-layer furnace body outer wall promptly can play heat preservation effect again to the heating of double-layer furnace body outer wall, can further utilize the heat of flue gas, reduce the outlet temperature of flue gas;
4. water return outlet and hot water outlet differ 180 degree and the set-up mode of upper/lower terminal in the horizontal direction and are arranged in the water return outlet place and flow out from hot water outlet after backwater racecourse bend in the double-layer furnace body all can make backwater fully absorb heat again, and can prevent effectively that cold water from entering heating system;
5. helix tube is divided into different inside and outside two of screw diameter, and every all has import, the outlet of tangentially joining with double-layer furnace body, two imports differ 180 degree in the horizontal direction, two outlets differ 180 degree in the horizontal direction, can so that in water in two helix tubes and the flue from top to down flue gas fully carry out heat exchange, increase heating surface area, improve heat exchanger effectiveness, simultaneously can also in double-layer furnace body, form eddy current, improve the heat transfer speed of water in interior hot water of helix tube and the double-layer furnace body, leaving water temperature is even, and can effectively prevent scale formation;
6. set be provided with the serviceability that radiation heat insulation lid, condensed water port and moulded coal ring washer etc. all can improve boiler.
