Since the next million years ago, biomass direct combustion, is converted to heat energy has been done ancestors. They burn wood, leaves for cooking and warm the body. Today, we have a lot more efficient technology through biomass heat. Some plants use this technique to direct combustion to produce steam.
Direct combustion method can be seen in some plant that uses sugar cane bagasse from sugar manufacturing process. Steam engine produces electricity using steam heat, which rotate the generator wheel. Waste oil distillation machines, send partly to sugar plant operation and employee's residence.
