Double Flame Retardant Gasifier

Abstract

The present invention is a double flame retardant gasification furnace, which mainly consists of a furnace body 1, a furnace cover 21, a double flame retardant 2, a lifter 19, a suction fan 15, a spiral pipe 22, a gasification chamber 11, a feed port 3, and an air inlet 7. Composition of a safety valve 12, characterized in that: a spiral pipe 22 is arranged above the furnace cover 21, a suction fan 15 is connected above the pipe, and a double flame retardant 2 is arranged above the gasification chamber 11 in the furnace body 1 and connected to it The lifter 19, the double flame retardant covers the top of the fuel 4, and automatically descends when the fuel is consumed during the combustion process, so that the double flame retardant and the fuel are always in close contact, resulting in serious oxygen deficiency above the fuel. Oxygen to ensure that the fuel is always kept in a dark fire state and fully gasified. It has the advantages of high gas production, stable gas production, simple structure, convenient operation, and strong practicability. The full use of it is conducive to environmental protection.

Description

Technical field [0001] The invention relates to a gasification furnace, that is, a double flame-retardant gasification furnace. Background technique [0002] In recent years, a variety of gasification stove products have emerged in an endless stream. Most of their structures are composed of a furnace body, a gasification chamber and a gas chamber. In the gasification chamber, it is ignited and decomposed in an oxygen-deficient state to produce combustible smoke gas, which is supplied and burned as an environmentally friendly new energy gas. This kind of product is popular because of its simple structure and low cost, and its economic benefits and market value are relatively obvious. However, the main problem of these stoves is that it is difficult to control the oxygen supply to the gasification chamber, thus resulting in the disadvantages of low gas production, unstable gas supply, and poor gas quality. At present, the methods used in the prior art to control the oxygen su...

Problems solved by technology

However, to adjust the size of the air inlet, the adjustment range is very limited, and according to the state changes caused by the combustion in the furnace, it is difficult to match the air intake of the adjusted air inlet size, resulting in unstable gas production; use a fan to blow air to the air inlet , because the air volume of the existing fan is fixed, but during the combustion process in the furnace, the air volume required according to different combustion states, that is, the oxygen supply volume is variable, so the size of the fan is also difficult to match. In addition, the air volume It is also difficult to evenly enter the furnace, so the fuel in the furnace burns unevenly, which also causes unstable gas production; humidifying the fuel in the furnace will cause high humidity of the gas and make it difficult to burn
