Abstract

The utility model relates to a three-use boiler taken fuels such as straw, raw coal and molded coal, consisting of a boiler main body, a water return pipe and a water discharging pipe, wherein the water return pipe and the water discharging pipe are respectively communicated with the boiler main body. The whole boiler is a water sleeve structure with a sandwich layer. The lower part of the boiler body is a combustion chamber. The combustion chamber is connected with a vertical smoke discharging passage. The combustion chamber and the smoke discharging passage are both the water sleeve structures. The lateral wall of the combustion chamber is connected with a plurality of reheating pipes positioned in a hearth. A supporting platform is arranged at the lower part of the combustion chamber. A grate bar which can be replaced is arranged on the supporting platform. A boiler door is in the opening-shape. The utility model adopts the water sleeve structure in which a sandwich layer is arranged, which increases the heating area of the heat interchangeableness in the combustion chamber. Compared with the common boiler, the utility model increases more than 30% of the area of the heating interchangeableness. The structure of the utility model is simpler than the structure of the prior boiler and easy to be manufactured; therefore, the manufacturing cost of products is lowered. The combustion chamber in the utility model can replace the grate bars with different structures and be suitable for different fuels such as the straw, the raw coal and the molded coal.

Description

Stalk, raw coal, Moulded Coal Three-Purpose Boiler

Technical field:

The utility model relates to a kind of boiler, particularly a kind of stalk, raw coal, Moulded Coal Three-Purpose Boiler.

Background technology:

Boiler combustion generally is fully burning in burner hearth with fire coal or combustion gas, and internal conversion becomes heat energy in the unit interval.In conversion process, owing to be subjected to multiple effects limit such as material, area, time and space, the heat of all burnings all can not be changed into the heat energy of water, be to take to utilize the flue recovery technology in the prior art, but the heating surface area of combustion chamber and flue is limited in the prior art, has influenced the raising of boiler thermal energy conversion rate, such as, in the prior art, the comb of boiler has only its outer wall to participate in heat exchange, has limited the area of boiler participation heat exchange like this.

Summary of the invention:

It is big that the purpose of this utility model provides a kind of endotherm area, the stalk that thermal conversion rate is high, raw coal, Moulded Coal Three-Purpose Boiler.The purpose of this utility model realizes by following structure: the utility model is a kind of stalk, raw coal, Moulded Coal Three-Purpose Boiler, constitute by boiler body and the return pipe that is communicated with boiler body respectively and outlet pipe, boiler integral body is a jacket structure for water that has interlayer, the body of heater bottom is the combustion chamber, the combustion chamber connects a vertical smokejack, combustion chamber, smokejack are jacket structure for water, sidewall of combustion chamber connects a plurality of post bake pipes that are positioned at burner hearth, the bottom, combustion chamber has supporting station, removable fire grate is installed on the supporting station, and fire door is uncovered shape.The utility model takes to be equipped with the water jacket form of sandwich, has increased the heating surface area of heat exchange in the combustion chamber, has improved the thermal efficiency of the present utility model greatly.The utility model heat pipe is installed at the combustion chamber vertical direction, effectively absorbs the heat in the combustion chamber, increases heat exchange area more than 30% than common boiler.Structure of the present utility model is simpler than existing boiler structure, manufactures easily, has therefore reduced the manufacturing cost of product.The utility model can be changed the fire grate of different structure in the combustion chamber, can be fit to multiple different fuel combustion, can be fit to stalk, raw coal, three kinds of different fuels of moulded coal, the utility model fire door is the easier cleaning carbon distribution of uncovered shape, can utilize instrument cleaning carbon distribution at any time.The utility model can be accomplished with less space sectional area, its heating surface area of bigger displaying, and energy savings is comparatively desirable version.
