Abstract

The utility model relates to a boiler which is characterized in that a water jacket is composed of the inner and the outer walls of the boiler body, a spiral type water pipe which is formed by a plurality of cross and spiral water pipes is arranged in the boiler body, and both ends of the water pipe are communicated with the water jacket. Sector-shaped spaces among cross water pipes of each layer are connected by a sector-shaped connecting board, and thus a spiral type flue is formed. A boiler grate in the boiler body is provided with an energy-saving net which is provided with a plurality of holes, an air inlet pipe which is extended outside the boiler body is arranged between the spiral type flue and the net, the outer wall of the boiler body is provided with a water supply pipe and a drain pipe, and the boiler body is respectively provided with a smoke pipe, a water outlet pipe, and a normal pressure pipe. Because spiral type flue is additionally arranged in the boiler body, the heat energy of smoke can be fully absorbed by the water in the spiral type water pipe, the purpose of energy saving can be achieved, and the utility model is a good civil boiler.

Description

A kind of boiler

The utility model relates to a kind of stove, specifically a kind of boiler.

At present, the hot cigarette major part that heating boiler commonly used is produced when burning is all emitted in vain from smoke pipe, weak point such as have that burning is insufficient, exhaust gas temperature is high, contaminated environment, the thermal efficiency are low.

The purpose of this utility model is to develop a kind ofly, the heat of burning fully can be absorbed the boiler that improve boiler thermal output, reduces the environmental pollution degree, economizes on coal, economizes on electricity.

Major technique content of the present utility model is, a kind of boiler, by body of heater, water jacket, water pipe, fan-shaped connecting plate, energy saving net, grate, smoke pipe constitutes, it is characterized in that, the body of heater inside and outside wall constitutes water jacket, in body of heater, be provided with the spiral water pipe that some water pipes intersections are spiraled, two of water pipe communicates with water jacket, connect the fan-shaped space that produces between every layer of intersection water pipe with fan-shaped connecting plate and form a spiral flue, energy saving net with some holes is housed on grate in body of heater, between spiral flue and energy saving net, be equipped with a blast pipe outside the logical body of heater, at furnace body outer wall feed pipe and blow-off pipe are housed, on body of heater, be respectively equipped with smoke pipe, outlet pipe and normal pressure pipe.Its operation principle, coal in the burner hearth by primary combustion after remaining fuel gas carry out second-time burning again for wind by energy saving net and secondary, enter spiral flue then and intersection is spiraled into water in spiral water pipe and the water jacket heat the back cigarette once more and discharge from smoke pipe again.

The utility model is compared the advanced part that is had and is with prior art, this stove and accessory has reasonable in design, can make burning produce heat advanced parts such as heat is fully absorbed in body of heater inside spin formula flue uphill process that fuel gas burns once more and produced, thereby overcome weak points such as existing stove is time-consuming, expense coal, contaminated environment.

Description of drawings:

This figure is just cuing open perspective view for the utility model;

Below in conjunction with accompanying drawing the utility model is remake description further, furnace body outer wall 1, inwall 2, constitute water jacket 15, in inboard wall of furnace body 2, be provided with the spiral water pipe 4 that some water pipes intersections are spiraled, two of spiral water pipe 4 communicates with water jacket 15, connect the fan-shaped space that produces between the spiral water pipe 4 with fan-shaped connecting plate 8 and form a spiral flue, energy saving net 3 with some holes is housed on grate 12 in inboard wall of furnace body 2, between spiral flue and energy saving net 3, be equipped with a blast pipe 14 outside the logical body of heater, at furnace body outer wall 1 feed pipe 9 is housed, blow-off pipe 10, outside body of heater, be provided with fire door 13, ashpit 11, on body of heater, be provided with smoke pipe 6, outlet pipe 5 and normal pressure pipe 7, more than just constitute the utility model.

Claims
