Technology Considerations for Coal-to-Gas Conversions

Changes in boiler heat transfer temperature profile – Lower furnace heat absorption – Higher furnace exit gas temperature – Reduction/elimination of slagging and fouling conditions Reduced auxiliary power requirements. A boiler feasibility study should be conducted to verify proper heat absorption rates and tube and steam temperatures.

Optimal Combustion Process - Fuels and Excess Air

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:
