Description

A kind of power economized boiler

Technical field

The utility model relates to a kind of boiler, and specifically a kind of boiler with energy-saving effect, be applicable to industry heating, the oven dry such as indoor heating, cultivation, chemical industry.

Background technology

The boiler that uses at present, furnace grate tube is a comb, does not rationally utilize furnace cavity, and coal containing quantity is little, burns insufficient, and burning time is short, and the fire grate heat exchange area is little, and waste fuel; Air heat was to utilize Boiler Steam or hot water or medium in the past, obtained institute's calorific requirement by the outer heat exchange of heat exchanger furnace, its complex structure, cost of investment is large, install inconvenient, waste energy and effect also bad.

Summary of the invention

For above defective, the utility model provides a kind of power economized boiler, adopts the design of undaform furnace grate tube, rationally utilize furnace cavity, corresponding increase furnace grate tube, thus increase the boiler heat exchange area, and can be disposable throwing foot fuel, extended burning time, reduce labor intensity.

for reaching above purpose, the utility model has adopted following technical scheme: a kind of power economized boiler, from the bottom to top by base, base, fire grate, furnace shell forms, be provided with lower furnace in described furnace shell, upper furnace, one backhaul smoke pipe, two return smoke pipe and three backhaul smoke pipes, a described backhaul smoke pipe is connected with lower furnace with upper furnace, the two return smoke pipe, three backhaul smoke pipes are respectively by the upper inner-liner top board, the bottom inner container top board is connected with lower furnace with upper furnace, lower furnace is provided with shoot door and feeding gate, base is provided with shoot door, be provided with smoke baffle plate in lower furnace, fire grate, be provided with the undaform furnace grate tube in described lower furnace, a described backhaul smoke pipe outer shroud is around heat exchange coil.

Described heat exchanger tube described in the utility model is divided into heat exchange coil, U-shaped heat exchanger tube and secondary heat exchange coil pipe from the bottom to top; The boiler top is provided with secondary heat exchanger, described secondary heat exchange coil pipe is located in secondary heat exchanger, and secondary heat exchange coil pipe, heat exchange coil, U-shaped heat exchanger tube are integrated, described U-shaped heat exchanger tube be distributed in heat exchange coil around, the bottom air inlet is provided with circulating fan, and the top is the gas outlet; Described heat exchange coil inwall is evenly distributed with inner fin.

After adopting above technical scheme, the beneficial effects of the utility model are: can effectively utilize furnace high-temperature water or medium, force the heat in heat exchange coil and U-shaped heat exchanger tube and outside air or medium circulation heat exchange by blower fan fast, thereby reach the purpose of energy-saving heating, and scaling not in flue, its compact conformation need not other heat transmission equipment, stable working, easy to use.

Below in conjunction with drawings and Examples, the utility model is further described.
