Coal Gasification based Production of Direct Reduced Iron

Jan 25, 2020Coal is pulverized and fed to the gasifier through two sets of horizontally opposed burners using a transport gas (either syngas or nitrogen). Preheated O2 and steam (as a moderator) are mixed and fed to the injector, where they react with the coal to produce syngas consisting mainly of H2 and CO with only small amount of CO2 and no hydrocarbon

Optimal Combustion Process

Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent excess air. Typical values of excess air for some commonly used fuels are shown in the table below:
