Single-stage gasifier , with 20mm-60mm bituminous coal or anthracite as fuel, is the gasification technology of a series of chemical reactions working inside gasifier., which consists of oxidization, reduction, pyrolysis and drying. Etc. After the technical disposal with optimized alloction of dust-removing , tar-removing and cooling ,etc., the clean coal gas out of gasifier is supplied to industrial kiln by gas pressure adding and transmission system. Hot coal gas and cold coal gas technology are defined according to requirements of different kilns. The whole system includes coal yard, slag yard, coal lifting system, coal bunker, coal feeding system, air supplying system. single-stage gasifier gasifying system. dust-removing and purifying system, light oil catching and recycling system , auto-control system, gas storage, pressure adding and transmission system.
Advantages of single-stage gas producer
1. Simple process, less land, less investment and simple operation;
2. Mechanical coal feeding, wet slag discharge, no secondary pollution;
3. The gas outlet temperature is 400-550℃, and the heat energy utilization rate is extremely high;
4. Mainly used for: chemical heating, heat treatment furnace, boiler coal gasification transformation, refractory material industry
