Description

Energy saving and environmental protection coal-fired firewood multi-purpose gasifier

technical field

The utility model belongs to the technical field of civil heating equipment, in particular to a combustion furnace which directly converts coal, firewood and all combustible substances into gas through chemical reaction under high temperature conditions.

Background technique

In the civil heating or cooking stoves of the prior art, most of them are single functions of burning coal and firewood. In the stoves that see coal or firewood into combustion gas, the combustion is not sufficient, and the thermal efficiency is low. In rural areas, orange stalk fuel is not enough, and coal is still needed. Therefore, a general family has two stoves for burning wood and one for burning coal.

In a word, the existing civil stoves have single function, single type of firewood, complex structure, high energy consumption, poor environmental protection, and high cost, which are not suitable for energy saving and environmental protection requirements, nor for the needs of the current socialist new countryside construction.

Utility model content

In order to overcome the existing deficiencies in the current civil stoves, the utility model provides a multi-purpose gasification gasifier with simple structure, reasonable layout, high thermal efficiency, low energy consumption, low cost, sufficient combustion, no black smoke, energy saving and environmental protection. furnace.

The technical scheme adopted by the utility model to solve the technical problems is: an energy-saving and environment-friendly coal-fired firewood multi-purpose gasifier, which is composed of three parts: the furnace water jacket, the upper, middle and lower water jackets of the furnace mouth, and the flue water jacket assembly. Large; the oxygen supply device with fan supplies oxygen to the bottom of the furnace and the air inlet distribution room in the combustion area through the air duct, regulating valve, and multi-air pipes, and the combustion is sufficient; it is composed of a movable grate base and a furnace cover. The three parts of the water jacket are connected into a positive body by welding and communicate with each other; the oxygen supply device is connected to the furnace bottom part and the combustion zone part for combustion. To ensure sufficient oxygen supply, a blower is installed, and a blower is installed to adjust a reasonable air intake Regulating valve and reasonable air passages with multiple air passages, the grate is divided into a fixed part and a movable part, and the movable part is shaken by a rocker to make the furnace ash fall easily, and an ash half is provided for ash cleaning.

Main technical features of the utility model energy-saving and environment-friendly coal-fired firewood multi-purpose gasifier:

1. The gasification furnace is fed with coal firewood and all combustible substances, and combustible gas is burned, which has strong firepower and rapid heating;

2. Multi-water jacket combination design, full use of heat, high thermal efficiency, fast heating speed, twice faster than coal-fired furnaces;

3. Not restricted by coal type, all kinds of coal, firewood and all combustible substances can be burned;

4. Energy saving and environmental protection, burning semi-bituminous coal, bituminous coal, various firewood and all combustible substances without emitting black smoke;

5. The forced air intake device with multi-air inlets provides sufficient oxygen supply and adjustable firepower to ensure full combustion;

6. It has complete functions and can be used for cooking, heating and bathing at the same time. It can be used for cooking in restaurants, drying agricultural products in rural areas, and heating greenhouses;

7. It is easy to use, and it can burn continuously with one coal addition, and the fire sealing time for normal coal addition is more than 20 hours;

8. It can be used as a separate heat pipe for heating and heating heater, with small liquid capacity and fast heating.
