Abstract

The utility model discloses an energy conserving boiler. The structure comprises a boiler plate arranged at the lower part of a boiler body, a boiler liner arranged at the upper part of a boiler cavity, and a smoke exhaust pipe arranged at the top part of the boiler body, wherein the boiler plate is composed of a plurality of energy conserving pipes arranged in parallel, the boiler liner is composed of two layers, the upper layer is a prismatic boiler liner , and the lower layer is two cone shaped boiler liners, the prismatic boiler liner is fixed through the energy conserving pipes and connected with the two cone shaped boiler liners, and the water jacket formed by the inner and outer layers of the boiler body is connected with the boiler liner and the energy conserving pipes. The utility model enhances the thermal efficiency, reduces the heat loss, the staying time of the coal in the boiler cavity is increased, pollution to the environment is reduced, the heat-absorbent area is increased, the water circulation speed in the boiler liner is enhanced, so as to quicken the speed of water temperature rising, and the utility model can be widely used in civil heating occasions.

Description

Power economized boiler

Technical field

The utility model relates to the civil boiler technical field.

Technical background

Civil boiler great majority commonly used adopt flue are set in burner hearth, and the stone or metal plate for standing a stove on as a precaution against fire below the burner hearth is made up of a plurality of parallel iron bars side by side, and smoke exhaust pipe is arranged on the top of body of heater.Though this kind boiler is simple in structure, easily produce, in use exist many shortcomings, insufficient as the coal burning, time of staying weak point in burner hearth, the temperature of discharging fume outward is too high, waste heat energy, contaminated environment simultaneously, water circulation in the flue is slow, and it is slow to heat up, and heat transfer rate is low, and thermal losses is big.

Summary of the invention

The utility model provides a kind of novel energy-conserving boiler overcoming the deficiencies in the prior art, its technical scheme is: its structure includes the stone or metal plate for standing a stove on as a precaution against fire that the bottom is provided with in the body of heater, the smoke exhaust pipe at the flue of upper furnace and body of heater top, wherein said stone or metal plate for standing a stove on as a precaution against fire is to be made of a plurality of parallel energy-saving pipes side by side, energy-saving pipe is communicated in flue, described flue is made up of two-layer, the upper strata is the prismatic flue, lower floor is located at burner hearth two conical flues on every side, two conical flues are fixed and be communicated in the bottom of prismatic flue by energy-conservation stationary pipes, the water jacket that interlayer forms inside and outside the body of heater is fixed and be communicated in the top of prismatic flue also by energy-conservation stationary pipes, the top of water jacket extends to the exit, top of smoke exhaust pipe, simultaneously, water jacket is communicated in conical flue and extends downwards with the energy-saving pipe of forming stone or metal plate for standing a stove on as a precaution against fire and communicates.

The utility model is owing to adopt double-deck flue, every layer of flue reasonably is distributed in the burner hearth, therefore flue absorbs the heat that coal fully burns and produces as much as possible, improve the thermal efficiency, reduce thermal losses, simultaneously, the abundant burning of coal in burner hearth, increase the time of staying of coal smoke in burner hearth, reduced pollution environment; Water jacket communicates double-deck flue with fixing energy-saving pipe, has increased endotherm area, has improved the circulation rate of water in the flue, makes the water quick heating; The stone or metal plate for standing a stove on as a precaution against fire that is made of energy-saving pipe and the water jacket of smoke exhaust pipe periphery have also fully absorbed the waste heat of whole boiler.
