Burner for pyrolysis and gasification and combustion method thereof

Abstract

The invention relates to the technical field of combustion equipment, in particular to a combustor for splitting decomposition and gasification. The combustor comprises a furnace body, a liquid conveying pipe and a combustion chamber arranged inside the furnace body, wherein a plurality of airflow holes are formed in the combustion chamber; the combustion chamber is connected with a gasifier; a guide pipe is arranged inside the gasifier; an output hole is formed in the top end of the guide pipe; the liquid conveying pipe penetrates through the combustion chamber to be communicated with the guide pipe; a gasification chamber is arranged inside the gasifier; a plurality of metal particles for performing splitting decomposition and gasification on fuel are arranged inside the gasification chamber; during the use, fuel enters the gasifier through the liquid conveying pipe, under the high temperature action of the gasifier, one part of fuel in the gasifier is gasified, the other part of fuel forms atomized particles to be in contact with the high-temperature metal particles, the atomized particles are further subjected to splitting decomposition and gasification through the high-temperature metal particles, and finally mixed combustible gas is formed to enter the combustion chamber to be fully combusted. Obviously, the combustor has the advantages of being simple in structure, stable in combustion, and capable of saving fuel.

[0002] At present, in places such as hotels, guesthouses and large canteens, in order to improve cooking efficiency, a large number of liquid fuel burners are used. At the same time, among these burners, alcohol-based liquid burners have the advantages of fast heating, low use cost and environmental protection. advantages and are widely used; however, the existing alcohol-based burners generally mainly include two parts: a combustion chamber and a gasifier. Under the action of the high temperature of the gasifier, it is converted from liquid to small molecular gas, and enters the combustion chamber from the bottom of the gasifier to mix with air and burns. Since the gasifier is directly connected to the combustion chamber, when there is a large amount of fuel When injecting, the part that cannot be gasified in time will also directly enter the combustion chamber. For example, when the user needs to increase the combustion, he will often release the valve to inject more fuel. At this time, a large amount of fuel suddenly increases into the combustion chamber. Carburetor, the internal air of the gasifier is limited, the gasification efficiency is reduced, and the ungasified fuel enters the combustion chamber, resulting in low combustion efficiency and insufficient combustion, resulting in a decrease in the amount of fire within a period of time and increased fuel consumption; In view of this, the inventor has proposed a cracking gasification burner and its combustion method after repeated tests and demonstrations based on his own professional knowledge in burner-related fields for many years
