TECHNICAL FIELD

[0001] The utility model relates to the technical field of gasification furnace air blowing, specifically to a kind of biomass gasification furnace air blowing device. BACKGROUND

[0002] In the operation process of biomass gasification furnace, air blowing device plays a vital role. It not only can provide necessary oxygen to support combustion process, but also can improve combustion efficiency through reasonable air distribution. However, the existing biomass gasification furnace air blowing device has some deficiencies in design.

[0003] However, many air blowing devices in the prior art lack effective air filtration mechanisms. Without proper filtration, impurities and particulate matter in the air can enter the combustion system before being introduced into the burner, which not only reduces combustion efficiency, but also can cause damage to the internal structure of the gasification furnace. On the other hand, the existing air blowing device has limitations in air flow control. Traditional air blowing devices can only provide fixed air flow, and cannot be flexibly adjusted according to the combustion demand. This lack of flexibility limits the combustion efficiency and performance of the gasification furnace under different operating conditions.

[0004] Therefore, a new type of biomass gasification furnace air blowing device is proposed to solve the above problems. The device not only includes an effective air filtration mechanism to ensure that the air entering the burner is clean and free of impurities, but also realizes flexible control of air flow through innovative design. By adjusting the angle of the guide plate inside the device, the amount of air delivered by the air blower into the burner can be accurately controlled, thereby optimizing the combustion process and improving the overall performance of the gasification furnace SUMMARY

[0005] The utility model aims at providing a kind of biomass gasification furnace air blowing device to solve the problems raised in the above background.
