The beneficial effects of the utility model are, by several boiler tubes that arrange, increased the backhaul of cigarette, increased the flue gas heat exchange time, by preheater, reduce the temperature of smoke evacuation, by Double fire grate back burning is set, increase the thermal efficiency and power, played the effect of economizing on coal and reducing discharging, solved that existing boiler smoke heat-exchange time is short, the thermal efficiency is low, the problem of high fume temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of power economized boiler of the utility model.
In figure, 1. ashes chamber, 2. cast iron grate furnace, 3. water jacket grate furnace, 4. return pipe, 5. refractory wall, 6. boiler tube, 7. water-level gauge, 8. thermometer, 9. outlet pipe, 10. body of heater, 11. flue air regulating boards, 12. chimneys, 13. feed pipes, 14. emptying tracheaes, 15. preheaters.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of power economized boiler, and its structure, referring to Fig. 1, comprises body of heater 10, in body of heater 10, is provided with water circulating pipe, and the below of body of heater 10 is provided with combustion chamber, and below, combustion chamber is provided with ashes chamber 1, and a side of body of heater 10 is provided with chimney 12.Wherein, combustion chamber comprises water jacket grate furnace 3 and the cast iron grate furnace 2 that is successively set on body of heater 10 belows; Chimney 12 is provided with preheater 15 near one end of body of heater 10, and preheater 15 is provided with emptying tracheae 14, and the port of export of chimney 12 is provided with flue air regulating board 11; The outer wall of body of heater 10 is provided with water-level gauge 7 and thermometer 8; Body of heater 10 comprises inner chamber and exocoel, described water circulating pipe comprises several boiler tubes that is set in parallel in side by side inner chamber 6, the two ends of each boiler tube 6 are all communicated with exocoel, the outer wall of body of heater 10 is provided with outlet pipe 9 and the return pipe 4 being interconnected, described preheater 15 is provided with feed pipe 13, and described outlet pipe 9, return pipe 4 and feed pipe 13 are all communicated with exocoel; The inner chamber of body of heater 10 is vertically provided with refractory wall 5, and gap is left on one end of refractory wall 5 and inner chamber top.
Point stokehold, water jacket grate furnace 3 and cast iron grate furnace 2 are paved with to timber, light and coal, open flue air regulating board 11 and be adjusted to correct position, self-priming normal combustion, in combustion process, the water jacket grate furnace 3 on upper strata falls down and does not fire the timber that clean broken coal is lighted lower floor's cast iron grate furnace 2, and lower floor takes fire, and forms two-layer burning, then the fuel continuation that water jacket grate furnace 3 is fallen down on upper strata is in 2 afterburnts of lower floor's cast iron grate furnace, and ash content falls into ashes chamber 1.
Cooling water is entered from feed pipe 13, then enter several boiler tubes 6 by the inner chamber of body of heater 10, then export from outlet pipe 9 by boiler tube 6, then by return pipe 4, be back to the inner chamber of body of heater 10, complete water cycle process.
The outer wall of body of heater is provided with water-level gauge 7 and thermometer 8, can the temperature of Real-Time Monitoring boiler and the state of recirculated water.
The setting of refractory wall 5, makes body of heater 10 inner chambers form the path of a U-shaped, and the cigarette that combustion chamber produces rises to the top of body of heater 10 from a side of refractory wall 5, move to again the exit of chimney 12, increased the backhaul of cigarette, the preheater that simultaneously chimney 12 places arrange, can reduce the temperature of smoke evacuation.
By several boiler tubes 6 that arrange, increased the backhaul of cigarette, increased the flue gas heat exchange time, by preheater 15 is set, reduced the temperature of smoke evacuation, by Double fire grate back burning is set, increase the thermal efficiency and power, played the effect of economizing on coal and reducing discharging, solved that existing boiler smoke heat-exchange time is short, the thermal efficiency is low, the problem of high fume temperature.
