Module 1 Objective Type Each question carries One mark 1. The energy sources, that are either found or stored in nature are a) Secondary Energy Sources b) Primary Energy Sources c) both (a) and (b) d) none of the above 2. Natural Gas contains ? a) 95-99%
· Natural gas would normally be used for boiler lightoff, initial warming, and low load operation; coal would then be used, either alone or in conjunction with natural gas, to achieve rated capacity. While the addition of natural gas firing will eventually help the facility realize reduced fuel cost, it may take longer to reach the "break-even" point due to conversion and installation costs.
In direct firing system, coal is milled on line and is directly fed to the kiln. The primary air is used to dry the coal. High moisture coal is not suitable for direct firing, as this has the effect of lowering the flame temperature and therefore the process efficiency.

Co-firing can reduce the emission of a number of gases. It has already been established that these gases pollute the environment and can cause global warming. Co-firing, therefore, can be beneficial in a number of ways. The most important benefit we obtain from the co-firing system is CO2 reduction, usually associated with global warming. In addition to the above, we can benefit in the ...

· The delay in the Mitchell unit 3 conversion has not stopped biomass co-firing research, which has the potential to back out at least some of the coal normally used at the targeted plants. "The scope of Southern Company''s biomass testing program has included investigation of co-firing various types of biomass at existing pulverized coal power plants," Georgia Power said in the IRP.
