Abstract

A coal gasification integrated boiler is characterized in that the boiler is divided into three parts of an upper body of the boiler (6), a lower body of the boiler (16) and a boiler foundation (1). The upper body is divided into an internal casing and an external casing, with water between the casings. The internal casing is pierced by a pipe for connection. Inside a heating water pipe (7) is water. The external wall of the pipe is equipped with a flue combustion chamber (11). The lower body is a gas-generating chamber (12). The upper body and the lower body are communicated with each other through a connecting pipe (5) of the upper and lower bodies. The lower body is divided into an internal casing and an external casing. The bottom of the boiler is the boiler foundation (1), inside of which is an impounding ash removing tank. Above the tank is a primary chamber (17), of which the upper end is equipped with a grate. Fuels (14) are arranged on the grate.

Description

The coal generating gas integrated boiler

Technical field

The utility model relates to a kind of boiler, particularly relates to a kind of integrated boiler of making combustion gas with coal.

Background technology

Existing coal generating gas integrated boiler is the combination of producer gas generator and boiler, and its investment is big, and running cost height, producer gas generator are medium with the fire coal, make coal-fired gasification be converted into coal gas by steam, directly burn water in the heating kettle body of coal gas.And the used steam of the producer gas generator of existing coal generating gas integrated boiler be by the heat that the water in the closed container between the inside and outside body of heater absorbs body of heater carry out water, steam conversion is realized.Because the heating surface area of the water between the inside and outside body of heater in the closed container is little, the self-produced steam of the producer gas generator of existing coal generating gas integrated boiler has not satisfied the coal-fired requirement that is converted into coal gas, so, the gas yield of the producer gas generator of existing coal generating gas integrated boiler is low, makes the boiler rate of heating slow.Must replenish steam in order to improve gas yield, take external steam source of the gas to solve usually.Carbon monoxide can not fully burn, and also can pollute environment.

Summary of the invention

The purpose of this utility model is to provide a kind of coal generating gas integrated boiler, this boiler is connected in one with generation chamber and combustion chamber, cancelled coal gas storage chamber, make generation chamber not produce malleation, fuel is stratified combustion in body of heater, and coal gas comes out, and the back is direct burns, its sufficient combustion, safety, have not over-emitting black exhaust of chimney, heat is not wasted, the characteristics of environmental protection and energy saving.

The purpose of this utility model is achieved through the following technical solutions:

Coal generating gas integrated boiler, this boiler are divided into boiler upper body, boiler lower body and boiler foundation three parts, and the upper body is divided into inside and outside cover, inner room dress water, in cover pipe coupling, be subjected to be water in the pipe of hot-water line that the pipe outer wall is the quirk combustion chamber; Lower body is a gas generating chamber, and upper and lower body connects water pipe by last lower body and is connected, and lower body is divided into inside and outside cover, inner room dress water; Bottom of furnace body is boiler foundation, is the retaining ash removal pool in the basis; Be an air compartment on the pond, one time the air compartment upper end is a fire grate, places fuel above the fire grate.

Aforesaid coal generating gas integrated boiler, its boiler upper body are equipped with boiler water outlet, chimney, atmosphere connection interface; The boiler lower body is equipped with wash water valve, secondary air standpipe, backwater interface and a fire door, an ash door.

Advantage of the present utility model and effect are:

The utility model is connected in one with generation chamber and combustion chamber, has cancelled coal gas storage chamber, makes generation chamber not produce malleation, fuel is stratified combustion in body of heater, and coal gas comes out, and the back is direct burns, and makes its sufficient combustion, safety, have not over-emitting black exhaust of chimney, heat is not wasted, the characteristics of environmental protection and energy saving.

Description of drawings

Accompanying drawing is the utility model one-piece construction synoptic diagram.

Embodiment

With reference to the accompanying drawings the utility model is elaborated.

As shown in the figure, the utility model is partly formed by three, and first is boiler upper body 6 partly; Second is boiler lower body 16 partly; The 3rd partly is boiler foundation 1.The upper body is divided into inside and outside cover, middle dress water, in cover pipe coupling, be subjected to leak water in the pipe of hot-water line 7, the pipe outer wall is quirk combustion chamber 11, the upper body is equipped with boiler water outlet 8, chimney 9, atmosphere, and to be communicated with interface 10 lower bodies be gas generating chamber 12.Upper and lower body is gone up lower body connection water pipe 5 by two and is connected, lower body is divided into inside and outside cover, middle dress water, lower body is equipped with wash water valve 15, secondary air standpipe 13, backwater interface 2 and fire door 4, ash door 3 (coal filling hole, ash removing holes), and fire grate, solar or lunar halo and secondary solar or lunar halo are arranged at the bottom.Secondary solar or lunar halo is delivered to lower body top with wind, and one time solar or lunar halo is sent wind into bottom of furnace body, and bottom of furnace body is boiler foundation 1, is the retaining ash removal pool in the basis.The utility model drops on the basis after boiler is made up, water reservoir is piled water, waterborne is an air compartment 17, one time the air compartment upper end is a fire grate, put fuel 14 igniting above the fire grate, its principle is: during fuel combustion, produce carbon monoxide, carbon monoxide is gone to the secondary air zonal combustion, enters the boiler upper body and fully burns, after the fire in a stove before fuel is added burnouts above the fire grate, after ashes fall into the water and produce water vapour and enter the furnace bottom fire and mix, make furnace bottom be in the anoxycausis state and increase the generation of carbon monoxide, fully burn at secondary air upper end carbon monoxide like this, make chimney not arrange black smoke, reach the integrated incendiary optimum regime of coal generating gas.

Claims

1. the coal generating gas integrated boiler is characterized in that, this boiler is divided into boiler upper body (6), boiler lower body (16) and boiler foundation (1) three part, the upper body is divided into inside and outside cover, inner room dress water, in cover pipe coupling, be subjected to be in the pipe of hot-water line (7) water, the pipe outer wall is quirk combustion chamber (11); Lower body is gas generating chamber (12), and upper and lower body connects water pipe (5) by last lower body and is connected, and lower body is divided into inside and outside cover, inner room dress water; Bottom of furnace body is boiler foundation (1), is the retaining ash removal pool in the basis; Be an air compartment (17) on the pond, one time the air compartment upper end is a fire grate, places fuel (14) above the fire grate.
