      Origin. Co-firing (also referred to as complementary firing or co-combustion) is the combustion of two different fuels in the same combustion system. Fuels can be solid fuels, liquid fuels or gaseous, and its source either fossil or renewable.Therefore, use of heavy fuel oil assisting coal power stations may technically be considered co-firing. However, the term co-firing is used in the

      Incineration - Wikipedia

      Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".Incineration of waste materials converts the waste into ash, flue gas and heat.
