Abstract

The utility model discloses a coal gas generating furnace equipped with a heat-resistance liner. A layer of heat-resistance liner is added on the inner wall of the original jacket boiler of the coal gas generating furnace, the direct contact between the high temperature charcoal and the inner wall of jacket is disabled, byproduct steam is reduced, carbon residue in the slag is decreased, the raw material consumption is efficiently reduced, and the purpose of energy conservation is realized.

Description

A kind of producer gas generator with the thermal resistance liner

Technical field:

It is the simple stationary gas producer of raw material that the utility model relates to the carbonaceous solids.

Background technology:

The temperature of producer gas generator gasification layer is very high, can reach 1100-1300 ℃ usually, therefore in industrial application, mostly is that the jacket boiler that constitutes with double-layer plate is as the furnace wall.In order to prevent that jacket boiler from being burnt out, the water of packing in chuck produces steam in cooling jacket.In actual use, water wall is taken away a large amount of heats, and is low owing to temperature near the raw material of water wall simultaneously, therefore can not burn, and discharges with slag with the carbon residue form at last.

In the ordinary production, the heat of steam loss that water wall produced accounts for the 5-7% of total energy consumption, near water wall and aphlogistic cold charcoal circle, because factors such as furnace temperature, output and granularity, nearly 30-50mm is thick, the calorific loss that causes is about 3-5%, and these two thermosteresis are equivalent to the 8-12% of total energy consumption.In these heats, utilize again though there is part to become steam, just present, all be to make gas feed coal price much larger than bunker coal, remain non-remunerative economically, because these steams can replace with used heat, slag and low grade coal fully.

Summary of the invention:

The purpose of this utility model provides a kind of producer gas generator with the thermal resistance liner, can reduce unnecessary heat-energy losses, effectively prolongs the work-ing life of jacket boiler in the producer gas generator.

The technical solution of the utility model is: in the jacket boiler of producer gas generator, being close to the jacket boiler inwall increases by a circle thermal resistance liner, add liner after, former burner hearth internal diameter does not change;

The material of described thermal resistance liner adopts relatively poor heating resisting metal or the non-metallic material of heat conductivility;

Described thermal resistance liner can be an one-piece construction, also can do and be in strip tile, along jacket boiler inner ring proper alignment, forms a complete hollow cylindrical.

Beneficial effect: after adopting above-mentioned measure, make the pyrocarbon that is produced aborning directly not contact with water wall, heat resistant layer forms the zone of transition of a heat conduction, make temperature progressively drop to 180 ℃ from 1300 ℃, charcoal deblocking temperature near the thermal resistance liner remains on more than 900 ℃, though slightly calorific loss does not influence aerogenesis, reduce carbon residue loss and thermal energy conduction loss more than 80%.

The utility model can use on the producer gas generator of various models, as: Φ 1600, Φ 2260, Φ 2400, Φ 2610, Φ 2650, Φ 2800, Φ 3000, Φ 3200, Φ 3600 etc., can obtain obvious effects.

The utility model can not only reduce unnecessary heat-energy losses, can also effectively prolong the work-ing life of jacket boiler in the producer gas generator.

Description of drawings:

Fig. 1 is the utility model cross section structure synoptic diagram.

As shown in the figure: in the jacket boiler 1 of producer gas generator, be close to the inwall of jacket boiler 1, increase by a circle thermal resistance liner 2.

Claims

1. the producer gas generator with the thermal resistance liner is characterized in that: in jacket boiler, be close to jacket boiler inwall increase by one circle thermal resistance liner.

2. according to the described a kind of producer gas generator with the thermal resistance liner of claim 1, it is characterized in that: this thermal resistance liner adopts heating resisting metal or non-metallic material to make.
