Most large coal fired plants have a flue gas desulphurisation (FGD) plant to lower SO2 levels to below emission limit levels. The CODEL GCEM 40 series is used to monitor SO2 levels after the FGD to ensure they are below required levels and to ensure that the process is not too efficient and using too much sorbent. In addition, many plants monitor pre and post the FGD to ascertain the efficiency of the plant.
In accordance with "Standard for pollution control on the municipal solid waste incineration" (draft), all existing and new the municipal solid waste incinerators need automatic continuous on-line monitoring of main ingredients in incineration flue gas. Monitoring projects should include at least HCl, SO2, NOx, soot, etc., but also need to detect CO and HF in some higher environmental requirements situations.
Power plants are industrial facilities used to generate electric power with the help of one or more generators which convert different energy sources into electric power. Power plants need to monitor emissions continuously according to local emission regulations. Read about our solutions for the power industry!
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. The demand for emission measurements has only increased in recent years and the trend will undoubtedly continue. It is therefore increasingly important for power plants to have reliable information available on emission of air pollutants. A power plant’s license to operate can even depend on it. Because the reduction of emissions to desired levels requires significant...
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives...
According to US EPA IO - 3.3 standard method of heavy metals, flue gas heavy metals analyzer uses XRF nondestructive testing technology and flue gas automatic enrichment technology to realize the accurate measurement of flue gas heavy metals such as waste incineration plants, cement plants, thermal power plants, etc.
Raw gases are untreated flue gases that have not passed through an emissions control technology system like selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR). They are generally measured for the sakes of process control and warranty tracking. Typically only a few components are measured but fourier transform infrared spectroscopy FTIR technology allows the measurement of all components.
With decades of industrial experience, our systems are designed and developed as a complete turnkey solution. From sample extraction, through analysis, data acquisition and report management, each system is configured to comply with the normative demands and technical constraints of our clients, specific to their industry.
In many industrialized nations it is common practice to use incineration methods for waste disposal. There are also ways to recover energy from the process. However, operating an incinerator requires strict adherence to environmental regulations. Hazardous, clinical and waste to energy incinerators can benefit from our EcoSorb range of activated carbon. Specially designed to adsorb unwelcome airborne compounds from flue gases.
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
For the removal of mercury emissions from flue gas streams, Calgon Carbon`s specialty PAC products are proven industry performers. These industries include: Coal-fired electric power plants, Cement, Boilers.
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.
The installation of suitable installation material in buildings is a cost effective way to reduce energy costs. The manufacture of insulation from minerals or mineral products, such as glass. Recycling glass to form insulation materials is another way to keep the process "green".
There are many locations that should be measured and monitored with a portable emissions analyzer to maximize product quality, combustion efficiency, safety, and emissions reduction in a cement plant including the following:
Cogeneration, or combined heat & power (CHP), is the utilization of boilers, turbines, and/or engines to simultaneously generate electricity power and heat that can be useful in several ways such as for hot water, steam, district heating, and water desalination.
Use of PROMECON`s innovative measurement technology McON Air in the air volume control in a waste incineration plant. PROMECON`s digital McON Air flow meter, enables enhanced control of the under grate primary air. Lower NOx, better control of combustion, lower grate wear. Also the flue gas flow can be monitored drift free at any point in the process!
Flue-gas analyzers are designed to be rugged and accurate at the same time. They are used by the HVAC industry, energy industry, process control, glass industry, food industry, universities and analysis is required.
Three Steps of CEMS:
1st Step: Gas Sampling
2nd Step: Gas conditioning and treatment
3rd Step: Measurement/Calibration
In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part.
The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance
2, Filtration Grade: usually 2 or 3 micron
