Embodiment 1
[0044] A methanol plant with an annual output of 100,000 tons uses coal-water slurry as raw material, and adopts a gasifier gasifier equipped with cluster gasification or combustion nozzles as shown in Figure 1 and Figure 2. The device produces 303 tons of methanol per day and processes coal every day. 400 tons;
[0045] Structural parameters of cluster gasification or combustion nozzles:
[0046] The outer diameter of the shell 5 is 260mm, and 7 nozzles are used. The diameter of the inner casing is 31×3mm, the diameter of the outer casing is 39.6×3, and the center-to-center distance between the outer casing 3 is 80mm; the nozzle height H is 2000mm, and the U-shaped piece The fixed position L of 1 and cover plate 2 is 40mm;
[0047] In the inner casing, the velocity of the coal slurry outlet is ~2m / s;
[0048] In the outer casing, the gas outlet velocity is ~100m / s;
[0049] The pressure of the gasification furnace is 4.0MPa, the gasification temperature is 1300°C, the ash ...
Embodiment 2
