Description

A kind of power economized boiler

The utility model relates to a kind of water heater that heat-generating device is arranged.

The vertical boiler that tradition is used, its heat exchanger tube all is the vertical setting of types pipe, the inner chamber that heat energy that the combustion chamber internal combustion produces and high-temperature flue gas pass the vertical setting of types pipe, discharges from chimney behind smoke-box, vertical setting of types pipe and smoke-box place in the hydroecium, carry out heat exchange with water in the hydroecium.The vertical boiler that this tradition is used, its drawback is: 1, the heating surface area of vertical setting of types pipe is little, and the thermal efficiency is low; 2, chimney is young, and to the smoke-box cleaning difficulty of being stopped up by flue dust easily, it is insufficient to burn, and the thermal efficiency also can reduce.

The purpose of this utility model provides a kind of thermal efficiency height, the smoke-box power economized boiler of cleaning easily.

This power economized boiler, comprise furnace shell, inner chamber hypomere at furnace shell is provided with chamber wall, the lower end of chamber wall and furnace shell medial surface are fixed, the upper end is connected as a single entity with the smoke-box wall, basal surface position corresponding to chamber wall is provided with and the fixing fire grate of furnace shell, the part that the inner chamber of furnace shell is positioned under the fire grate is the slag chamber, the inner chamber of chamber wall is the combustion chamber, the inner chamber of smoke-box wall is a smoke-box, chamber wall, gap between smoke-box wall and the furnace shell is an outer water chamber, on furnace shell, be provided with the slag notch that is communicated with the slag chamber, the coal feeding pipe mouth that is communicated with the combustion chamber, the water inlet pipe mouth that is communicated with the bottom of outer water chamber and steam that is communicated with the top of outer water chamber and hot water out pipe mouth, in smoke-box, be placed with and the fixing inner bag of smoke-box wall, the inner chamber of inner bag is interior hydroecium, the upper and lower of interior hydroecium is communicated with outer water chamber respectively, heat exchange pipe is housed in the combustion chamber, its design feature is that heat exchange pipe is a transverse tube, each transverse tube hermetically passing chamber wall among every row, its two ends are communicated with outer water chamber, the upper end of smoke-box wall is uncovered and pass on the furnace shell end face and stretch, at extension socket one chimney cowl of smoke-box wall, chimney cowl is provided with throat.

As improvement to this power economized boiler, on furnace shell, be provided with the hot water out pipe that is communicated with the middle and lower part of outer water chamber, the blow-off pipe that is communicated with the bottom of outer water chamber, water valve is housed respectively on hot water out pipe and the blow-off pipe, water level displaying tube is housed on water inlet pipe mouth, the upper end of water level displaying tube is communicated with the top of outer water chamber by connecting the mouth of pipe, and row's number of heat exchange pipe is 1-3 row.

Boiler described in the utility model, the heat energy that combustion chamber internal combustion coal is produced directly heats the outer surface of horizontally-arranged pipe, give water in the horizontally-arranged tube cavity by heat exchange with thermal energy transfer, its heating surface is the outer surface of horizontally-arranged pipe, with the vertical tube heating surface of general-purpose vertical boiler is that inner surface is compared, increased heating surface area, improved the thermal efficiency, again owing to be placed with inner bag in the smoke-box, increased an interior hydroecium, make in the combustion chamber high-temperature flue gas that produces not only with outer water chamber in water carry out heat exchange, also with interior hydroecium in water carry out heat exchange, make full use of the waste heat of high-temperature flue gas, further improved the thermal efficiency, by the contrast experiment, boiler described in the utility model is compared with traditional vertical tube vertical boiler, and 25-30% can economize on coal.Because chimney cowl of the present utility model can take off from the upper end of smoke-box wall easily, make that the smoke-box wall is uncovered to be exposed again, thereby be convenient to clean smoke-box.

Accompanying drawing shows the embodiment of this power economized boiler, and wherein Fig. 1 is the structural representation of power economized boiler, and Fig. 2 is the A-A cutaway view of Fig. 1.

In the present embodiment, power economized boiler comprises furnace shell 1, inner chamber hypomere at furnace shell 1 is provided with chamber wall 2, the lower end of chamber wall 2 and furnace shell 1 medial surface are fixed, the upper end is connected as a single entity with smoke-box wall 3, basal surface position corresponding to chamber wall 2 is provided with the fire grate of fixing with furnace shell 14, the part that the inner chamber of furnace shell 1 is positioned under the fire grate 4 is slag chamber 5, the inner chamber of chamber wall 2 is combustion chamber 6, the inner chamber of smoke-box wall 3 is a smoke-box 7, chamber wall 2, gap between smoke-box wall 3 and the furnace shell 1 is an outer water chamber 8, on furnace shell 1, be provided with the slag notch 9 that is communicated with slag chamber 5, the coal feeding pipe mouth 10 that is communicated with combustion chamber 6, the water inlet pipe mouth 11 and the blow-off pipe 21 that are communicated with the bottom of outer water chamber 8, the steam and the hot water outlet 12 that are communicated with the top of outer water chamber 8, the hot water out pipe 20 that is communicated with the middle and lower part of outer water chamber 8, on hot water out pipe 20 and the blow-off pipe 21 water valve 22 is housed respectively, water level displaying tube 23 is housed on water inlet pipe mouth 11, the upper end of water level displaying tube 23 is communicated with the top of outer water chamber 8 by connecting the mouth of pipe 24, in smoke-box 7, be placed with inner bag 15, the inner chamber of inner bag 15 is interior hydroecium 16, inner bag 15 is fixed on the smoke-box wall 3 by upper support pipe 13 and lower support pipe 14, interior hydroecium 16 is communicated with outer water chamber 8 by upper support pipe 13 and lower support pipe 14, heat exchange pipe 17 is housed in combustion chamber 6, heat exchange pipe 17 is transverse tubes, its row's number is 1-3 row, that draw in the accompanying drawing is 2 rows, each transverse tube hermetically passing chamber wall 2 among every row, its two ends are communicated with outer water chamber 8, the upper end of smoke-box wall 3 is uncovered and pass on furnace shell 1 end face and stretch, at extension socket one chimney cowl 18 of smoke-box wall 3, chimney cowl 18 is provided with throat 19.
