ABSTRACT A two-stage upflow process for coal gasification. An oxygen-containing gas and a first increment of a coal-in-water slurry are ignited in a horizontal fired slagging reactor by means of horizontal coaxial juxtaposed burner nozzles mounted in the reactor, thereby converting the oxygen, the coal, and the water into steam and gaseous combustion products.

Gasification of coal. Gasification of coal is a conversion technology which converts any carbon (C) containing material, such as coal, into synthesis gas (syngas). It is a high temperature process with temperature reaching typically 1,225 deg C. The temperature is optimized to produce a fuel gas with a minimum of liquid and solids.

In this system, coal is fed into the gasifier in the form of coal-water slurry; the water in the slurry serves as both a transport medium (in liquid form) and a gasification medium (as steam). This system operates at 1,500 °C (2,700 °F), so that the ash is removed as molten slag. Gas-cleanup systems

Coal gasification involves the conversion of coal into electricity, hydrogen, and other energy products. Gasification is a thermo-chemical process that breaks down coal - or virtually any carbon-based source - into its basic chemical constituents. In a modern gasifier, coal is typically exposed to steam and carefully controlled amounts of air or oxygen under high temperatures and pressures ...
