Innovative Technology

        The top-suction atmospheric fixed-bed gasifier product developed by Guangzhou Huanyu has won the second prize of Science and Technology Progress Award of Guangdong Light Industry Association. Compared with similar domestic products, it includes a number of advanced technical designs:

        (1) Innovative double-sealed feeding bin design: a double-sealed feeding bin (patented technology) is installed on the top of the gasifier main body. On the one hand, it can strengthen the sealing effect during the feeding process of the gasifier and prevent biomass Gas leaks, leading to safety accidents; on the other hand, it can be used as a temporary and transient storage of biomass gasification raw materials, which can ensure the tightness of the feeding equipment during the troubleshooting process, and the gasification furnace feed is normal, which improves the gasification furnace Safety and reliability of operation.

        (2) Unique tower-type air distribution structure design: the gasifier adopts a unique tower-type uniform air distribution structure, which is not easy to be blocked, ensures the gasification efficiency, enhances the reliability of the gasifier, and can achieve uniformity. The air distribution can prevent the silo from burning, especially in the process of stuffing (hot standby). It can provide effective gasification agent support to ensure the effective continuity of the stuffing and prolong the stuffing time up to more than 10 days.

        (3) Unique water-cooled tower eccentric grate design: through the unique water-cooled tower eccentric grate design (patented technology), the grate has a long service life, usually more than five years, and can achieve a good biomass charcoal Broken bridges and discharged carbon will not stop the furnace due to coking and agglomeration, affecting production.

        (4) Unique gas purification and tar recycling technology: through innovative gas purifier structure design (patented technology), oil and gas separation can be achieved well, tar and dust in the crude gas at the outlet of the gasifier can be removed, and biomass gas can be prevented Conveying pipelines, equipment and burners are blocked to improve the safety of the system, and to create zero tar recycling technology. After the tar is recovered, the gasifier is used for secondary pyrolysis and gasification to avoid the tar directly sent to the boiler for combustion. Due to insufficient combustion, serious scaling on the heat exchanger surface and reduced boiler efficiency are caused.

        (5) Innovative multi-stage low-nitrogen combustion technology: innovative biomass gas low-nitrogen burner design (patented technology), at least two gas channels of different sizes are set on the coaxial line to form a multi-stage burner with adjustable power. Low-nitrogen combustion can be realized, and the combustion power can be controlled by controlling the number and corresponding size of the gas channels used to adapt to different power needs. The overall structure is simple and easy to install.
