Methane Sensing for Coal Mining

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Application: The majority (around 60%) of the coal seams currently being extracted worldwide are so far underground that open cast mining cannot take place and, therefore, underground mining techniques need to be used. Consequently, workers have to enter and work in confined spaces. One of the major problems that this creates is the dangers from Methane (CH4) gas which occurs in Mine gas.

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 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.

Gas Sensing for Gasification

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Syngas (short for synthetic gas) can be burnt and used as a fuel source, the main constituents of syngas are Carbon Monoxide (CO) and Hydrogen (H), which amount for around 85% of Syngas, and it is produced by a process called Gasification. Gasification starts with a base material which can originate from a wide variety of materials for example wood chips and pellets, plastics, municipal solid waste, sewage, waste crops, and fossil fuels such as coal. During Gasification the base material is reacted at high temperature without combustion with controlled amounts of oxygen (O) or steam. The composition of the base material combined with the amount of oxygen and heat used in the process affects the composition of the resultant SynGas, in which the CO can vary between around 20 and 60%. In addition, large amounts of H and CO are also formed. The measurement of CO is therefore an important feature in the production of SynGas.

Fly Ash - Industrial Vacuum

by Vac-Con, Inc.     based in Green Cove Springs, FLORIDA (USA)

Fly Ash can cause many problems. The Vac-Con & Vector Pneumatic Vacuum systems can assist and solve many of these problems. Our high-performance vacuum systems are manufactured in three basic configurations: Truck mounted, Trailer mounted, and Fixed/static installed. Any of these systems can be integrated into the existing power plant design. All of our vacuum systems can be utilized to solve your plant’s fly ash removal/clean-up needs and can assist in many other maintenance projects. All can be tailored to fit into your power plant’s specific needs. Vac-Con Truck mounted Industrial vacuum systems are equipped with large storage debris tanks with self-cleaning intake filter systems. The Industrial Trucks vacuum the waste products through existing manifold piping or with hoses attached directly to the debris tank. When fully loaded, the truck can then drive directly to the disposal site and discharge the waste products. The Industrial Truck offers a great amount of flexibility of operation and can be utilized anywhere in your facility for many different types of normal and emergency maintenance operations. The Vac-Con Industrial Vacuum Truck can be utilized on both wet and dry materials. The same Vac-Con truck can be used for removing Fly Ash from your plant, coal from broken intake belt conveyors, or used to suck wet muddy material from storage lagoons. The Vector Trailer mounted Vacuum Systems are designed to be used in several locations around power plants. The Trailer mounted Vacuum Systems connect to Manifold piping located in key areas within your power plant. The Vacuum systems move the waste products from the plant and deposit these products into moveable storage containers. The loaded storage containers when full can then be moved to the disposal sites for discharge. Vector Static Mounted Vacuum systems are designed to vacuum and remove Fly Ash and other bulk waste products through manifold piping from operational areas of the plant and deposit these waste products into collection storage silos for later transport to disposal sites. The fixed vacuum systems are electric motor driven and are normally installed as a permanent addition to in-plant existing conveying systems. Please contact us with any requirements you may have. We will evaluate your request and respond with solutions specific to solve your problems and fit your needs.

Agitation and mixing solutions for flue gas desulfurization

by National Oilwell Varco     based in Dayton, OHIO (USA)

FGD (Flue Gas Desulfurization) involves the treatment of flue gas from coal fired power plants.  The main goal is to remove sulfur, particulates, and other chemicals such as mercury from the flue gas prior to environmental release.  Governmental regulations by the EPA put limits on the amount of impurities which can be released into the air.   The use of mixers to clean and scrub the flue gas is utilized to help power companies meet permitted limits on the release of controlled substances.

Air pollution control for ventilation air methane industry

by Anguil Environmental Systems, Inc.     based in Milwaukee, WISCONSIN (USA)

Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM).  The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG.  As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat.  Landfills and mines represent two of the most abundant sources, however reports indicate that more than 50% of all VAM is exhausted from mine ventilation systems and remains unutilized.
