At present, raw materials used by a gasification furnace are particles or small blocks, a crusher is required to be equipped to crush common raw materials, the raw materials are required to be in a dry state, and gas making is greatly influenced by moisture. The gasifier in the existing market is single in shape, small in size and incapable of being used continuously, the material poking operation needs to be carried out after the gasifier is used for a period of time, the machine needs to be stopped to carry out the feeding operation after the furnace materials are used up, and the service efficiency of the gasifier is greatly reduced. When feeding, the gas to be burnt must be leaked, which causes pollution to the environment and harm to human body.

The materials burned in the furnace are accumulated at the bottom of the gasification furnace, the machine needs to be stopped for slag removal operation, otherwise, the biomass in the furnace is incompletely burned, substances harmful to human bodies are generated, and the environment is polluted. The operation of the equipment needs the monitoring of an operator at a side station, the operations such as feeding or poking, ash digging and the like can be carried out, the supervision of the operator can not be left, and otherwise, the phenomenon of equipment shutdown is easily caused.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) because the equipment volume is small, the internal space is limited, the raw material storage in the furnace is reduced due to overlarge raw material particles, the combustion time of the gasification furnace is greatly shortened, the raw materials need to be crushed additionally, and the labor intensity is increased;

(2) the equipment volume is small, the raw material holding capacity is small, the raw material cannot automatically fall down after combustion, and the machine needs to be stopped to poke materials and remove slag, so that the combustion duration is short;

(3) when the material poking operation is carried out, the furnace cover needs to be opened, smoke generated by internal combustion leaks, and the respiratory tract of an operator is easy to be damaged;

(4) the insufficient combustion can be caused by the untimely slag removal, carbon monoxide and other substances harmful to human bodies are generated, and the environment is polluted;

(5) the filling can be carried out only once, the continuous feeding can not be carried out, and after the fuel in the furnace is burnt, the machine is stopped and the raw materials are added again;

(6) the humidity of the raw materials used for combustion is required to be below 20%, so that the available raw materials are greatly limited, and when the humidity is higher, the water in the closed furnace body is higher, and the combustion efficiency is seriously influenced;

(7) as mentioned above, the operation is performed by personnel, and the operation is separated from the personnel management, namely the normal operation cannot be realized.

The difficulty in solving the above problems and defects is:

(1) the raw materials are mostly broken wood, so that the hardness is high and the crushing strength is high;

(2) the raw materials can form accumulated ash after being combusted, so that the falling of the raw materials is influenced, and the full combustion is hindered; gas leakage is easy to cause during slag removal;

(3) in the continuous feeding process, the fuel gas is easy to leak from the feeding hole.

The significance of solving the problems and the defects is as follows:

(1) a user can add larger raw materials when using the coal pulverizer, so that the labor intensity of pulverizing before burning and the energy consumed in the pulverizing process are reduced;

(2) the automatic slag removal can automatically remove residues, then the raw materials automatically fall down to achieve the effect of continuous combustion, meanwhile, the whole operation process is carried out in a closed environment, no harmful gas is emitted, and great benefits are brought to human bodies and the environment;

(3) the uninterrupted feeding technology provides necessary conditions for continuous combustion;

(4) the user can use the raw materials with high humidity, so that the phenomenon that the raw materials cannot be normally used due to water vapor generated by stacking is avoided;

(5) the full-automatic technology can be used for equipment to be separated from personnel management for a long time, and labor is saved.
