The reaction temperature of circulating fluidized bed coal gasification is controlled below 1000℃. In this category, with the increase in temperature, the gasification chemical reaction rate will expand. Increasing the temperature will increase the carbon conversion rate and the production capacity of machinery and equipment, and is beneficial to liquefaction Improvement of gas composition. However, excessively high temperature may cause slagging safety accidents, block the fluidity of raw materials, and make manufacturing impossible.
What are the advantages of circulating fluidized bed gasifier compared with circulating fluidized bed in the temperature level of the plate bed?
Because the circulating fluidized bed (bubble bed) has a certain height of the dilute phase section, there is a large temperature difference along the height of the bed, and the temperature uniformity is weak. Compared with the circulating fluidized bed (bubble bed), the circulating flow The temperature of the fluidized bed is more evenly distributed throughout.
Characteristics of circulating fluidized bed gasifier
Compared with the circulating fluidized bed coal-fired steam boiler, the circulating fluidized bed coal gasifier is not so much the original characteristics, the circulating system is large, the solid particle concentration value is high, and the radial pressure difference in the furnace is large.
