Modern Wood Boilers - The Benefits of Batch Burning

The firing method most commonly employed for wood-fired boilers with a steam generation rate larger than 100,000 lb/hr is the spreader stoker. In this boiler type, wood enters the furnace through a fuel chute and is spread either pneumatically or mechanically across the furnace, where small pieces of the fuel burn while in suspension.

Boiler Efficiency: Introduction and Methods of Calculation

This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100
