Product Information
Synthetic composite pulverized coal gasification device is a gasifier that is composed of a circulating fluidized bed, a pulse conveying bed and an entrained bed. After the raw coal is crushed, the pulverized coal ≤ 6mm is sent from the coal preparation section to the gasifier coal hopper. The coal is fed into the lower part of the fluidized bed of the composite gasifier through the screw feeder at the bottom of the coal hopper. Air or oxygen is preheated and mixed with low-pressure superheated steam as the gasification agent and fluidization medium. It enters the gasification furnace from the air distribution plate at the bottom of the fluidized bed and enters the furnace for combustion and gasification reaction at 1000ºC. CO, H2, CO2, etc., high-temperature solid particles are classified and separated at the top of the gasifier through a horizontal fast separator, and large and medium particles are recycled back to the bottom of the gasifier through a return device for combustion and gasification reaction. The fine-particle carbon-containing fly ash enters the entrained bed at the lower part of the composite gasifier, where it undergoes high-temperature slag gasification at a temperature of 1300 ºC ~ 1500 ºC, and the molten liquid slag returns to the bottom of the gasifier to exchange heat with the fluidized material It is cooled and solidified, and the phase change heat of the liquid slag is recovered to provide part of the heat for the coal gasification reaction. The solid slag is finally discharged from the bottom of the furnace, and is sent to the slag field after heat exchange and cooling. The gas is sent to the gas tank after waste heat recovery, dust removal and other purification treatments to supply gas for the next section. Through the above measures, the problem of vomiting and diarrhea in the circulating fluidized bed is solved, fly ash is eliminated, and the methane content in the synthesis gas is reduced, which is beneficial to the synthesis reaction of the subsequent system.

Process characteristics
(1) Synthetic composite pulverized coal gasification equipment. One equipment has three parts: circulating fluidized bed, pulse conveying bed and entrained bed, realizing the staged gasification of coal; by setting up a horizontal high-efficiency gas-solid separator, solid particles The material enters different beds according to the different particle size, and respectively undergoes circulating fluidized bed gasification and entrained bed high-temperature slag gasification, liquid slag solid discharge, heat recovery. Integrating the advantages of each part, the feed size is as wide as the fluidized bed requirement, reducing the energy consumption of crushing; and the gasification effect is like an entrained bed, high production capacity, high gasification efficiency, and adaptable to different coal types and residues in slag Low carbon content and high carbon utilization.
(2) The synthesis gas produced by the synthetic composite pulverized coal gasifier has high content of effective components (H2+CO) and low methane content, which is suitable for synthesis gas; the coal type has strong adaptability and high gasification intensity; simple operation, startup and shutdown Convenient; partial desulfurization in the reactor is realized, and the load of the purification system is reduced; the high-temperature gas and liquid ash generated in the entrained bed provide heat for the circulating fluidized bed at the same time, and the liquid ash is converted into solid ash and discharged, and the ash discharge process is simple, Full use of heat.
