      How to Run a Coal Fired Boiler at the Best Efficiency

      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%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

      Pulverised Coal - an overview | ScienceDirect Topics

      The steam cycle is at the heart of coal-fired power plant efficiency. The efficiency of the Rankine cycle can be increased by introducing reheating of the steam after passage of the high-pressure turbine. Reheating not only improves the plant efficiency but also reduces the excessive moisture problem in low-pressure turbines.

      Pulverized Coal Fired Steam Boilers | Coal Fired Boilers

      Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels.
