Abstract

The utility model discloses a gasification combustion furnace which is composed of a furnace body, a main combustion chamber, an auxiliary combustion chamber, a cold water grate and a smoke exhaust port. The utility model is characterized in that a water jacket sandwiched layer of the furnace body is communicated with a water jacket sandwiched layer and the cold water grate of the main combustion chamber; the lower part of the furnace body is an insulative wall; two sides or the periphery of the auxiliary chamber is a heat collecting wall; a fire hole is arranged on the heat collecting wall of the auxiliary to be communicated with a burnout chamber; a fume hole is arranged on the upper of the burnout chamber; the main and the auxiliary combustion chambers are respectively provided with air inlet tubes. Because two sides or the periphery of the auxiliary combustion chamber are the heat collecting wall and are made of fire resistive materials or metallic materials, the gasification combustion furnace of the utility model performs the functions of heat preservation and heat collection; thus the combustible substances entering into the main combustion chamber can be burned in the auxiliary combustion chamber, and the temperature in the auxiliary combustion chamber rises rapidly; thus the combustible substances can be fully burned in the burnout chamber; thereby, the thermal efficiency of boilers can be improved, and the effect of energy conservation and environmental protection can be achieved.

Description

Gasification combustion furnace
Technical field
The utility model relates to a kind of industry or boiler for warming rooms.
Background technology
Energy-conservation and environmental protection is two unalterable quotas weighing industry or boiler for warming rooms, and the boiler of using is substantially all followed this aim now, adopts the gasification, and combustion principle mostly, but because structural design is unreasonable, has the improved drawback of some needs.All adopt the water cooled furnace wall as water-cooled grate with the sidewall of following subsidiary combustion chamber, reduced the temperature of subsidiary combustion chamber, made the combustible that enters subsidiary combustion chamber from main chamber, be not lost in vain owing to reach the flammable temperature of material, cause burning not thorough, insufficient.Boiler is not established to wind apparatus, and by the flue natural air inlet, the wind-force circulation is not enough, and boiler is easily smoldered, and can not reach environmental protection and two energy-conservation index requests, and the thermal efficiency is low simultaneously.
The utility model content
The purpose of this utility model is to provide the gasification combustion furnace of a kind of sufficient combustion, environmental protection and energy saving.
The technical solution of the utility model: gasification combustion furnace is made up of body of heater, main chamber, subsidiary combustion chamber, cold water fire grate and exhaust opening, exhaust opening is arranged on the body of heater upper end, major and minor combustion chamber upper and lower settings is in body of heater, water-cooled grate is arranged in the middle of the major and minor combustion chamber, and the front of major and minor combustion chamber is provided with fire door respectively; The water jacket samdwich of body of heater communicates with the water jacket samdwich of main chamber and water-cooled grate, the body of heater bottom is a heat insulation wall, the both sides of subsidiary combustion chamber or be the thermal-arrest wall of forming by refractory material or metal material on every side, have logical fire hole on the thermal-arrest wall of subsidiary combustion chamber and communicate with secondary furnace, the secondary furnace top has smoke hole; Major and minor combustion chamber is respectively equipped with blast pipe.
Described secondary furnace is arranged on the one or both sides of gasification combustion furnace subsidiary combustion chamber.
The wall of described main chamber blast pipe is provided with some air vents, makes the air-distribution that enters main chamber even, is convenient to abundant burning.
The utility model gasification combustion furnace, because subsidiary combustion chamber both sides or be the thermal-arrest wall all around, form by refractory material or metal material, has the heat-preservation heat-collection effect, the combustible that enters from main chamber is in the subsidiary combustion chamber internal combustion, makes that temperature raises rapidly in the subsidiary combustion chamber, and makes combustible fully completing combustion in secondary furnace, thereby improved the thermal efficiency of boiler, reached effect in energy saving and environmental protection.The utility model is applied widely, can be used for the hot-water boiler of warming oneself, industrial steam boiler and hot-blast stove application.
Description of drawings
Fig. 1 is the front view of the vertical gasification combustion furnace of the utility model;
Fig. 2 is the front view of the horizontal gasification combustion furnace of the utility model.
The specific embodiment
As shown in Figure 1, vertical gasification combustion furnace is made up of body of heater 2, main chamber 4, subsidiary combustion chamber 9, cold water fire grate 6, exhaust opening 1, secondary furnace 14 and thermal-arrest wall 11, exhaust opening is arranged on the body of heater upper end, and major and minor combustion chamber upper and lower settings is in body of heater, and the top, combustion chamber is provided with convection current and is subjected to hot-water line 3; Water-cooled grate is arranged in the middle of the major and minor combustion chamber, and the front of major and minor combustion chamber is provided with fire door 5,7 respectively, and the side communicates with blast pipe 12,13 respectively; The upward middle part of body of heater is a water jacket samdwich, communicates with the water jacket samdwich and the water-cooled grate of main chamber.The body of heater bottom is a heat insulation wall, the both sides of subsidiary combustion chamber or be thermal-arrest wall 11 on every side, form by refractory material or metal material, form secondary furnace 14 between the thermal-arrest wall of body of heater bottom and subsidiary combustion chamber, the thermal-arrest wall of subsidiary combustion chamber has logical fire hole 8 and communicates with secondary furnace, and the secondary furnace top has smoke hole 15; 16 is outlet pipe, and 17 is water inlet pipe.
As shown in Figure 2, horizontal gasification combustion furnace is another embodiment of the present utility model.This boiler is made up of body of heater 2, main chamber 4, subsidiary combustion chamber 9, water-cooled grate 6, exhaust opening 1, secondary furnace 14 and thermal-arrest wall 11, major and minor combustion chamber upper and lower settings side in body of heater, water-cooled grate is arranged in the middle of the major and minor combustion chamber, the front of major and minor combustion chamber is provided with fire door 5,7 respectively, and the side communicates with blast pipe 12,13 respectively; The top of body of heater is water jacket samdwich, communicates with the water jacket samdwich and the water-cooled grate of main chamber.The body of heater bottom is a heat insulation wall, the both sides of subsidiary combustion chamber or be thermal-arrest wall 11 on every side are made up of refractory material or metal material, at the subsidiary combustion chamber rear side secondary furnace 14 are set, have logical fire hole 8 on the adjacent thermal-arrest wall of subsidiary combustion chamber and secondary furnace, the secondary furnace top has smoke hole 15; 16 is water inlet pipe, and 17 is outlet pipe, and 18 is the body of heater smoke hole.
During gasification combustion furnace work, fuel burns in main chamber, it is combustion-supporting that fermented soya beans, salted or other wise blower fan generation air-flow enters blast pipe, flame and combustible and gas water flowing black furnace row's 6 space enters subsidiary combustion chamber 9, close subsidiary combustion chamber fire door 7, unburnt flame and combustible, in subsidiary combustion chamber, continue fully burning, flame enters secondary furnace 14 from the logical fire hole 8 of thermal-arrest wall, fuel gas completing combustion in secondary furnace, thereby improve the heat absorption and the interior temperature of stove of boiler, the flue gas of after-flame is discharged from the smoke gas port.
