Coal Gasification - an overview | ScienceDirect Topics

In Environmental Impacts of Coal Mining & Utilization, 1987. 4.1 Basic Principles. Coal gasification means the complete conversion of coal into gas using heterogeneous gas solid reactions. The main process is the reaction of the carbon of coal with steam, at pressures below 10 MPa and temperatures above 750°C, to form a “synthesis gas” containing mainly CO and

Coal Gasification - ZVU Engineering a.s.

Coal Gasification. The pressure gasifier with fix bed is the key equipment in the gasification of coal. The screened coal is periodically charged into the gasifier through the coal lock pressure hopper being mechanically controlled by the hydraulic cylinders. The feeding process is automatically controlled according gasifier operating conditions.
