Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
Energy & Power Plants / By Dr V T Sathyanathan / Mechanical Engineering. Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. ... The mill reject loss depends on the amount of pyrite in coal and the mill operating condition.
What is the efficiency of different types of power plants? Heat rate is one measure of the efficiency of a generator or power plant that converts a fuel into heat and into electricity.
