Combustion of Biomass Fuel and Residues: Emissions

Mar 02, 2017 · Most boilers burn fossil fuels like gas and oil to produce heat. While effective, the process emits carbon dioxide into the atmosphere which is one of the main causes of global warming. Put very (very) simply, a layer of carbon dioxide around the earth is stopping heat from escaping our atmosphere and is gradually heating up the planet.
