AI Technical Summary
Existing technologies lack effective experimental simulation devices for the permeability of coal and rock samples on the sidewall of the gasification chamber, which cannot accurately simulate the fluid permeation process and affects the adjustment of the gasifying agent and the reaction rate.
An experimental simulation test device for the permeability of coal and rock samples on the sidewall of a gasification chamber was designed, including a sealing shell, a sample receiving chamber, a homogenizer, multiple outlet channels, a flow pipeline, a fluid supply device, and a pressure controller, which can simulate the permeability of fluids under different conditions.
It provides accurate measurement data of coal permeability on the sidewall of the gasification chamber, supports the adjustment of gasifying agent injection rate and flow rate, and guides the production and control of underground coal gasification process.
