Product Description:

Introduction

Improved single-stage gas generator has overcome the inherent defects of the original single-section gas generator. With gasification efficiency and gas calorific value increased by 10%-15%, and the ash residue carbon content reduced by 10%-20%, the improved gas producer greatly reduced the labor intensity of operators and the failure rate of equipment.

Advantages

Low investment, large gas production, high heat utilization, complete gasification, wide adaptability of feed coal and simple operation.

Application

The improved single-stage gas generation furnace is widely used as metal heat treatment furnaces, ceramic kilns, aluminum melting furnaces, copper refining furnaces, forging and burning furnaces, metal products heating furnaces, galvanizing furnaces, drying furnaces, and annealing furnaces in chemical, refractory, cable and boiler industry, etc.

Improved single-stage gas generator Technological process:

After entering the coal field, the raw coal is broken, screened and transported to the coal storage layer (the coal storage bunker). Then, the coal is added into the furnace by the automatic coal feeder, transferred to the gasification section and reacts with the gasification agent to generate the gas (the gasification agent is composed of air and steam). The generated gas is exported via the outlet of the gasification section and enters the quenching and cooling tower (double vertical pipe). Then, it enters the scrubbing tower for further cooling and dust removal. Finally, after entering the pressurizing machine system for dehydration and desulphurization, the purified gas is sent to the gas supply point.
