And meanwhile, the heated superheated steam in the first resistance pipe and the second resistance pipe is sprayed into the combustion reaction chamber through the reaction chamber burner, so that on one hand, the sensible heat of the synthesis gas is absorbed, the physical temperature of the synthesis gas is reduced, on the other hand, the second-stage reaction k (chemical reaction rate constant) value is increased, and the endothermic reaction of coal and water vapor is enhanced. The invention can increase the disturbance of the air flow in the gasification furnace, enhance the reaction degree in the reaction chamber, improve the efficiency of the gasification furnace and ensure the efficient and stable operation of the gasification furnace.
Further, for the two-chamber type gasification furnace, the gasification furnace slag necking can slow down the flow speed of slag, and increase the heat exchange of the slag and the reaction of carbon in liquid slag. The necking of the exothermic reaction chamber can increase the slag hanging rate of the exothermic reaction chamber of the gasification furnace. The necking of the endothermic reaction chamber can increase the mixing of the gases in the endothermic reaction chamber to increase the reaction rate.
Furthermore, because the difference of the steam flow needed by the exothermic reaction chamber and the endothermic reaction chamber is large, a steam splitter is arranged to split part of the superheated steam generated by the first resistance pipe into the exothermic reaction chamber.
Furthermore, the flow of the water vapor in the two connecting pipelines can be monitored in real time through the first flowmeter and the second flowmeter, and the water vapor is reasonably distributed after being calculated through the controller, so that the utilization rate of the superheated water vapor is improved.
Furthermore, the superheated steam generator adopts the snake-shaped bent pipe arranged in the same plane, so that the heat exchange efficiency is high.
Furthermore, first resistance pipe and second resistance pipe are flat pipes, increase the resistance when improving the heated area.
Furthermore, the first resistance pipe and the second resistance pipe are perpendicular to each other, and the disturbance effect is improved.
Further, the interval between first resistance pipe and the second resistance pipe is less than the total high 1/5 of gasifier body, and the interval is too big, influences the heating effect.
Further, the distance between the second resistance pipe and the chilling gas nozzle is larger than 1/10 of the total height of the gasification furnace body; the position of the chilling gas nozzle is lower than the waste boiler inlet, and the distance between the chilling gas nozzle and the waste boiler inlet in the vertical direction is 1/10 the total height of the gasifier body; on the one hand, the influence of the cold gas on the heating effect of the second resistance pipe is avoided, and on the other hand, the cold gas and the coal gas can be fully mixed and then enter the waste boiler.
