Double-stage Coal Gasifier- Design and Mechanism

CASE Gasifier
Double-stage coal gasifier is designed for gasifying bituminous coal. Here, light tar is produced rom
coal in the pyrolysis section of the gasifier. The gas calorific value produced is higher as compared to single-stage gasifier. Engineers believe that double-stage gasifier offers Eco-friendly performance.

Design of Double-stage Gasifier

The structure of double-stage gasifier include coal feeding section, pyrolysis section, gasifying section, advanced upper roller, middle flashboard, wet slag removal system, plough-type special plate and more.

Mechanism in Double-stage Coal Gasifier

The advanced upper roller, middle flashboard and lower bell jar mechanism is used for coal feeding mechanism. The structure allows easy operation, maintenance and good gas tightness.

The wet slag removal attached to both side have self-designed plough-type plate for slag removal process.
