Review on Combustion Optimization Methods in Pulverised

Figure 1. Pulverised Coal fired boiler arrangement[3]. The concept of burning coal that has been pulverized into a fine powder comes from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of coal according to the boiler demand and the
