1. Direct Fired or Conventional Steam Boiler Most of the woody biomass-to-energy plants use direct-fired system or conventional steam boiler, whereby biomass feedstock is directly burned to produce steam leading to generation of electricity. In a direct-fired system, biomass is fed from the bottom of the boiler and air is supplied at the base.

Boiler - Wikipedia

Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Bagasse constitutes approximately 30 percent of the harvested sugarcane on a mass basis and typically has a moisture content of about 50 percent. The wet bagasse that comes out of the juice extraction system is directly sent to the factory's cogeneration system, where current practice is to burn it in boilers to generate high pressure steam.
