How to Run a Coal Fired Boiler at the Best Efficiency
Pulverized coal fired boilers the total losses account to about 12 to 14 % Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss
Coal Drying Improves Performance and Reduces Emissions
power plant, less coal needs to be fired This reduces the burden on the coal handling system, conveyers and crushers Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders
