Electrostatic Precipitator

by MEVADHASHMA     based in Coimbatore, INDIA

An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream.[1] 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 therefore is very efficient in its consumption of energy (in the form of electricity).

Coal pulverizing for the coal industry

by Columbia Steel Casting Co., Inc.     based in Portland, OREGON (USA)

Columbia Steel has established itself as a manufacturer of quality replacement parts for coal pulverizers and ash crushers used in power plants.

Coal Combustion Residuals Disposal for Power Plants

by CETCO     based in Hoffman Estates, ILLINOIS (USA)

Coal combustion residuals (CCR) are generated during the power generation process and can include fly ash, bottom ash, boilerslag, and flue gas desulfurization (FGD) residuals. CCRs contain trace concentrations of heavy metals and therefore cannot be dumped or stored where rainwater can leach the metals. Liner systems can be used to contain the coal combustion by-products and protect them from leaching into the environment.

Water treatment for power plants

by De Nora Water Technologies     based in Colmar, PENNSYLVANIA (USA)

The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.
