In Malaysia, the coal power output is unlikely to be decreased, as the current coal power stations in Peninsular are scheduled to close in 2029. With a forecast growth in coal consumption of more than 30 million tons per year, coal supremacy in the power supply sector is strongly expected (Malaysia Energy Commission, 2016). On the other hand ...

CO2 emissions from coal power generation could be reduced by maximizing the amount of torrefied biomass that can be used in pulverizedcoalfired power plants. In this study, to evaluate the milling performance of coal and torrefied wood pellets (TPs), various blend ratios were tested using a benchscale roller mill. Neutral sugar analysis was performed to evaluate the biomassderived part of ...

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, preheater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 3539% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
