Incineration Processes and Environmental Releases | Waste

Flue-gas recirculation systems are used to recycle into the furnace relatively cool flue gas (extracted after the heat exchangers have reduced its temperature) that contains combustion products and an oxygen concentration lower than air. or be used in tandem with, ESPs as the preferred design for particulate removal because of their

Selective Catalytic Reduction - an overview

Carlos E. Romero, Xingchao Wang, in Advances in Ultra-Low Emission Control Technologies for Coal-Fired Power Plants, 2019 3.2.2 SCR impact. SCR technology is successful in removing NO x in the flue gas. However, the impact of SCR on other emissions control devices needs to be taken into account, such as submicron particle forming, particle cohesion increase as well as SO 3 production.

Electrostatic precipitator - Wikipedia

An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and

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.

Ventilation (architecture) - Wikipedia

Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.
