Abstract
A preheating device for a refractory liner of a hot wall type coal water slurry or powered coal gasification furnace belongs to the technical field of hot wall type coal slurry gasification. By utilizing an operating nozzle of the gasification furnace to preheat the refractory liner of the gasification furnace, the process of replacing a preheating nozzle into the operating nozzle before feeding of the gasification furnace is eliminated, the feeding procedure of the gasification furnace is reduced, and the feeding success rate of the gasification furnace is improved. A fuel pipeline is connected to a coal slurry pipeline into the gasification furnace, a compressed air pipeline is connected to an oxygen pipeline into the gasification furnace, and fuel and compressed air are sprayed into the gasification furnace through the operating nozzle of the gasification furnace and ignited through an ignition device arranged on the operating nozzle of the gasification furnace to preheat the refractory liner of the gasification furnace. When the refractory liner of the gasification furnace is preheated to the feeding temperature, the fuel and the compressed air are cut off, and feeding of the gasification furnace operates. Flow meters and flow regulation valves are arranged on the fuel pipeline and the compressed air pipeline, and the heating rate of the gasification furnace in preheating is controlled by regulating the flows of the fuel and the compressed air.
