Emulsion-film absorber for cleaning flue gases from nitrogen oxides

Justification and basic design of emulsion-film type of absorber are given. An example of realization of technical solution to flue gas cleaning from nitrogen oxides and utilization of their heat, making use of an absorber built around a standard heat exchanging equipment (a pilot-scale air heater), is discussed. The equipment can be used to clean flue gases, heat blast air to 70°C, and raise boiler efficiency.
