AI Technical Summary
In existing technologies, low-concentration methane (3-8%) has not been effectively utilized as a resource, resulting in resource waste and safety hazards. Furthermore, existing technologies require enrichment processes, which increase costs and energy consumption.
A circulating fluidized bed system is adopted, which combines coal gangue and low-concentration gas combustion for power generation. Through gas grading and air stratification, a three-level air distribution mode of gas-air-gas is formed to dilute the gas concentration to a safe range and enhance turbulent mixing and combustion stability in the fluidized state. Combined with flue gas waste heat recovery for power generation.
It enables the efficient and clean utilization of low-concentration methane and coal gangue, improves combustion efficiency and safety, generates clean energy, and reduces energy consumption costs.
