Combustion Plant Applications

Coal Combustion Residuals Disposal for Power Plants

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.

Monitoring solutions for the flow combustion efficiency areas

Combustion efficiency is of major importance on small boiler plants and the best way to monitor this is by monitoring CO2 emissions. CODEL offer the Model 1010 Cross-Duct CO monitor. Using Infra-red Gas Filter Correlation technology to filter out interferences such as dust and other gases. The Model 1010 has low maintenance requirements and meets the needs of most boiler applications. In addition to small boilers the Model 1010 is also used on Animal carcass incinerators and Crematoriums.

Primary air control for coal-fired power plants

Power Generation Combustion Air Measurements: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements includ¬ing large ducts, limited metering runs, poor velocity and temperature profiles, high vibration, temperatures up to 750° F and dirty `Fly Ash` laden air.

Catalyst Monitoring Services

Catalyst monitoring services use periodic performance testing and lab analysis to track the condition of newly installed catalyst. The goal is to extend the life of the catalyst and it begins by establishing a relationship between operating hours and the catalyst’s condition and performance. Testing and analytical services reveal any decline in performance, direct catalyst maintenance services such as chemical washing, and provide a basis for estimating catalyst life. The scope of catalyst monitoring is scaled to the size of the installation – from a single reciprocating engine with one catalyst element, all the way up to a plant with multiple combustion turbines each having hundreds of catalyst elements.

Power Generation

Combustion turbines A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between. The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. The turbine shaft energy is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, so these have either a high temperature or a high velocity. A catalyst is often used to treat these exhaust gases to comply with emissions regulations. EmeraChem has installed OEM and after-market catalyst in over 240 applications
