up the stack. For example, the flue gas mass flow is higher in NGCC and IGCC power plants than in pulverized coal power plants [10] [13] [14]. Therefore, more heat is released to the environment through the stack and less heat load is sent to the cooling system, which means that less cooling water is needed.

Coal requirements per day of a large thermal plant are very large. A 600 MW power plant handles about 7200 tons of coal per day. Therefore, one of the major requirement of a power plant is to reduce the cost of handling of coal from the point of its origin upto the furnace of boiler where it is burnt.

The original operating parameters of the power plant as the load increases from 160 to 240 MW over 2 h are shown in Figure 5. A forced draft fan motor current (FFC) was used during boiler combustion to regulate the air flow rate entering the furnace. The results show that the FFC and coal flow change with the power output.
