Embodiment Construction
[0022] See attached figure 1 with figure 2 The gasification reactor 1 is divided into a dense-phase turbulent fluidization section 9, a high-density annular core flow section 10, and a high-density fast flow section 11, which are pressurized and segmented according to the gasification characteristics of coal with high sulfur, high ash, and high ash melting point Gasification, the gasification pressure is 1.0-2.5MPa. The dense-phase turbulent fluidization section 9 is a dense-phase area with a particle volume concentration of 0.3-0.45 and a material layer height of 2-5 m. It adopts a turbulent fluidization operation mode with a temperature of 850-1050 degrees and a gas velocity of 1-1.5 m / s. The function is to achieve good mixing and heat and mass transfer of bed material, coal and limestone A, gasification agent Q and primary return material H, as well as to carry out coal devolatilization, combustion and partial gasification reaction; the particle size of bed material is 0...
