ombustion
The direct burning of biomass in air to convert the chemical energy stored in biomass into heat, mechanical power or electricity using equipment such as stoves, furnaces, boilers or steam turbines. Combustion of biomass produces hot gases in the temperature range of 700–1000 °C. Combustion is feasible for biomass having less than 50% moisture content, otherwise the biomass have to be pre-dried [35]. As the energy efficiency is low (10–30%) and the pollutant emissions are the by-products, combustion is not a suitable hydrogen production for sustainable development.
