Abstract

The utility model discloses a secondary-combustion smokeless boiler. A boiler body of the boiler is a jacket structure, and is provided with a water feeding pipe and a water discharging pipe to form a circular heat exchange system; the front half part of the boiler body is provided with a hearth, a grate, a primary air pipe and a slag removing chamber; and the rear half part of the boiler body is provided with a flue and a chimney. The secondary-combustion smokeless boiler is characterized in that a secondary combustion chamber is arranged between the hearth and the flue; the middle part of the secondary combustion chamber is provided with a horizontal air distributing barrel; a plurality of sieving holes are uniformly distributed on the surface of the air distributing barrel; a barrel cavity of the air distributing barrel is connected with a secondary air pipe; and an air inlet of the secondary air pipe is arranged outside the boiler body. The secondary-combustion smokeless boiler disclosed by the utility model has the advantages that the secondary combustion chamber is arranged between the hearth and the flue, and the secondary air is introduced, the further combustion of fuel is enhanced, the full combustion of the fuel is promoted, the heat maximization of the combustion is realized, and no black smoke is generated, so that not only is the valuable energy saved, but also the pollution of the flue gas is reduced to be minimum, and the purpose of smokeless secondary combustion is achieved.

Description

A kind of second-time burning less boiler

Technical field

The utility model relates to the improvement of burning boiler structure, and a kind of second-time burning less boiler especially is provided, and belongs to the boiler technology field.

Background technology

Conventional combustion heat homogeneous solution-type reactor primary structure is made up of burner hearth, fire grate, coal feeding hole, breast hole, chimney and chuck body of heater etc.; Burn in burner hearth through fuel such as coals and to produce heat; Heat exchange medium through in the chuck body of heater comes out heat exchange, for the heat supply of hot system; And the flue gas that burning produces is directly discharged from chimney; Because the air that burner hearth gets into is limited, fuel often can not get abundant burning in the combustion process of burner hearth, just discharges from chimney, has not only wasted the valuable energy, and the also serious pollutant atmosphere of inadequate flue gas burns.

Summary of the invention

The utility model discloses a kind of second-time burning less boiler, and it is insufficient to have solved conventional hot-water boiler fuel combustion, produces air pollution, the problem that wastes energy.

The technical solution of the utility model is following: the body of heater of boiler is jacket structured, is provided with water inlet pipe and outlet pipe and constitutes the cycle heat exchange system, and the body of heater first half is provided with burner hearth, fire grate, airduct, Slag Room; The latter half of flue and the chimney of being provided with of body of heater; It is characterized in that: secondary combustion chamber is located between burner hearth and the flue; Be provided with horizontal cloth air duct at the middle part of secondary combustion chamber; The surface of cloth air duct is evenly distributed with some sieve apertures, and cloth air duct tube chamber is connected with secondary air channel, and the air inlet of secondary air channel is arranged on outside the body of heater.

At described second-time burning less boiler, it is characterized in that: between burner hearth and the secondary combustion chamber, be provided with reflection arch between secondary combustion chamber and the flue, reflection arch can be made into hollow-core construction and is communicated with the chuck of body of heater and constitutes cycling mechanism.

The utility model in use, fuel at first burns in burner hearth, the combustion gas of generation gets into secondary combustion chamber, in secondary combustion chamber, under the air that secondary air channel imports further fully after the burning, discharges outside the boiler through chimney again.

The good effect of the utility model is: between burner hearth and flue, set up secondary combustion chamber, introduce secondary wind, strengthened the further burning of fuel; Impel fuel to be able to sufficient combustion; The maximization of realization calory burning does not have black smoke to produce, and has not only practiced thrift the valuable energy; It is minimum that smoke pollution is reduced to, and reached the smokeless purpose of second-time burning.
