Biomass for Electricity Generation | WBDG - Whole Building

Direct combustion systems feed a biomass feedstock into a combustor or furnace, where the biomass is burned with excess air to heat water in a boiler to create steam. Instead of direct combustion, some developing technologies gasify the biomass to produce a combustible gas, and others produce pyrolysis oils that can be used to replace liquid fuels.

Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
