註釋

The aim of thermal waste treatment is to utilise the chemically fixed thermal energy to destroy toxic organic substances and, where possible, to provide waste energy recovery in the form of power or steam whilst minimising the impact of the process on the environment. Basic technologies for removal of acid gases, particulates and heavy metals from flue gas, such as the semi-dry process (spray adsorption), the wet process and effluent-free process are described in the paper. More recently developed "advanced gas cleaning" processes are also described. Catalytic and non-catalytic processes for removal of nitrogen oxides, using ammonia or urea as reduction agents, have yielded good results. More stringent emission limits for mercury and other heavy metals, and the limitation of dioxin/furan emissions have led to the development of adsorption systems using activated carbon or coke.
