Abstract

The utility model relates to a practical gas producer, which comprises a producer bottom, a producer body, and a producer top. The utility model is characterized in that the producer body is a structure of rectangular brick bonding; the producer bottom is provided with a self-tightening ash door and a water seal; the lower part of the producer body is provided with a water cooling pipe to self produce steam; the section of a hearth can be flexibly changed according to the requirements of gas production quantities of users. The utility model does not need fixed serial products, and the utility model can meet the requirements of various industrial furnaces.

Description

A kind of practical producer gas generator

The utility model relates to the inflammable gas generating unit.

Utilize coal to produce the device of coal gas, come out many decades, it is gradually improved technically, its superiority, particularly do not have flue dust, energy-conservation etc. early generally acknowledged, but shortcomings such as, running cost height big, long in time limit, and restricted its widespread use owing to its investment by people.

The purpose of this utility model is to provide a kind of practical producer gas generator.Its feature is simple in structure, less investment, easy to operate, makes the stove gasification of medium and small sized enterprises be transformed into possibility.It can be used for industrial furnaces such as heater for rolling steel, flint road kiln, roller kiln, down-draft kiln, glass-melting furnace.

Practical producer gas generator of the present utility model comprises furnace bottom, body of heater and furnace roof.Furnace bottom is made up of ladder fire grate, water seal tank or U type water sealed tank, ash door and steam and gasification wind inlet; Body of heater builds up with refractory castable, refractory brick insulating brick and insulating cotton, and a few water cooling tubes are established in the body of heater bottom, produce water vapor by plenum chamber, and upper of furnace body is established coal filling hole and gas exit; Furnace roof builds up with refractory brick or refractory castable, establishes several fire exploring holes on it.

Practical producer gas generator of the present utility model is that the burner hearth area can require according to user's gas consumption to change, and method is simple, must not establish the fixed series product, as long as build by laying bricks or stones and just at lateral widening.

Practical producer gas generator of the present utility model during with the industrial furnace adapted, can utilize the stove waste heat, gives hot combustion air, reaches requirements of saving energy.Even on high temperature stoves such as glass-melting furnace, also need not establish special-purpose regenerator.

Practical producer gas generator of the present utility model is in the furnace bottom coal water seal of setting up defences; The ash door adopts no folding self-tightening device, prevents gas leak; Furnace bottom is established the ladder fire grate, leaves slag extracting channel at the fire grate end.

Accompanying drawing is a specific embodiment of the utility model, and is existing as follows to the utility model commentary in conjunction with the accompanying drawings:

Coal is gone into stove from coal filling hole 3, and saturation steam and gasification wind 7 blast from entering the mouth, carry out gasification reaction with coal, coal gas is sent from exporting 10, and lime-ash is discharged from the slit and the slag extracting channel of ladder fire grate 6, fall into water seal tank 9, open self-tightening ash door 8, lime-ash can be dug out, in the bottom of furnace wall 5, if water cooling tube 4 a few, to produce water vapor, on furnace roof 2, establish several fire exploring holes 1.U type water sealed tank 11 can replace water seal tank.

Claims (1)
