AI Technical Summary

Technical Problem

The high-temperature screw conveyor of the biomass pressurized fluidized bed gasifier deforms and tears at the inlet and outlet due to temperature difference stress, which in turn causes leakage problems.

Method used

A self-balancing component, including a multi-link assembly and a counterweight, is installed on the casing of a high-temperature screw conveyor to automatically balance the stress difference between the inlet and outlet ends. Through the movement of the multi-link assembly and the action of the counterweight, the force is evenly distributed to avoid excessive stress.
