types of boiler flue gas dust removal

Selective Catalytic Reduction

Three basic system configurations have been used in power plant applications, depending on the location of the SCR unit relative to the dust and SO 2 removal units, as follows [1155]: High-dust arrangement (HD): The SCR unit is positioned immediately after the boiler. This configuration is used mostly in coal-fired applications, because the gas

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.

Indoor mold - Wikipedia

Because common building materials are capable of sustaining mold growth and mold spores are ubiquitous, mold growth in an indoor environment is typically related to water or moisture exposure and may be caused by incomplete drying of flooring materials (such as concrete). Flooding, leaky roofs, building-maintenance or indoor-plumbing problems can lead to interior mold growth.

Glossary of Mining Terms - Coal Education

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Boiler vs. Furnace Energy Efficiency | Constellation

Nov 11, 2016 · Upgrading your furnace or boiler from 56% efficiency to the 90% range, Energy.gov says, could save 1.5 tons of carbon dioxide emissions annually if you heat with gas. That number goes up to 2.5 tons if you heat with oil. Some easy ways to improve energy efficiency include considering the various types of furnaces or boilers.

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.
