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.

Sugarcane-Peanut Bagasse: As a non-conventional Boiler Fuel

boilers, bagasse boilers may use auxiliary fuels for start-up. In our case, the PNG is usually the start-up fuel, the initial sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions are higher than when bagasse alone is fired. The duration of startup typically for a normal bagasse boiler is up to 8 hours.

On the optimization of boiler efficiency using bagasse as

The individual contributions of all heat losses on the overall boiler efficiency have been determined, yielding an efficiency chart for these bagasse-boilers and the range of optimal stoichiometric ratio at the exit of the boiler, α b. For all the boilers analyzed, the optimal value of this parameter ranges between 1.5 and 1.55, for the whole range of steam power, contrasting with the 1.8 typically used prior to this study.

The most important characteristics of the fuel are their calorific or heating value. Each fuel has a certain range of heating values depending on its origin. In the case of wood, bagasse and other biomass, the moisture content will determine the range of heating values. All fuels contain hydrogen, which burns and produces water.
