Testing the Performance of a DeNOx System Using a Portable Emissions Analyzer
Using Portable Emissions Analyzers to Measure the Performance of a NOx Reduction System in a Power Plant Boiler
The majority of power plants utilize NOx reduction systems (eg. Ammonia Injection, SCR, etc.) in their power boilers to ensure that the NOx emissions levels comply with current regulations. The frequent evaluation of the De-NOx system is fundament...
There are many types of stationary and mobile internal combustion engines that can run off gas or diesel fuels. Engines can be lean burning at a high air to fuel ratio (AFR) or rich burning at a low AFR. The exhaust stack gases from engines contain pollutant gases including CO, NO, NO2, NOx, and CxHy hydrocarbons as well as particulate matter. Measuring the engine exhaust emissions is important for engine tuning, performance optimization, safety, and proving emissions...
When extracting and refining valuable geological materials from the earth (eg. limestone, aluminum oxide, gold), a variety of industrial combustion processes are required. The machinery used in these processes such as industrial engines, boilers, and smelters can emit highly toxic gases that are harmful to the environment and to human life. Using a portable emissions analyzer enables mining personnel to ensure personal and environmental safety, while optimizing the performance of the mining operation.
Marine vessels can emit air pollution such as CO, CO2, NOx (NO+NO2), and SO2 from their diesel engines and onboard incinerators. MARPOL Annex VI and the technical code for control of emissions of nitrogen oxides (NOx Technical Code) issued by IMO are internationally recognized regulations for the prevention of air pollution and emissions from marine vessels. Ships over 400 gross tons are also required to have an International Air Pollution Prevention (IAPP) certificate which...
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:
Fixed CEMS (Continuous Emissions Monitors) Measure at One Location
CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.
If the CEM is measuring emissions that are higher than the regulated or permitted...
Accurate emissions monitoring from industrial processes is critical for determining overall system combustion effciency, environmental compliance and safety. However, there is no “one-size-fits-all” approach to proper emissions monitoring as each application encompasses different system considerations. The art of emissions monitoring and sampling requires:
The Road to Environmental Efficiency: Monitoring Nitrogen Oxides (NOX) and Hydrocarbons (CXHY) for Combustion Efficiency and Environmental Compliance.
Why Monitor Nitrogen Oxides (NOx)?
Nitrogen oxides (NOX) are toxic gases common to combustion processes that are highly regulated by state and federal Environmental Protection Agencies (EPA). Exceeding the environmental limit not only compromises worker...
In recent years, combustible gas leak detection has grown in importance because of increased safety concerns, performances of products/systems, liability concerns, health concerns, and warranties. Gas leak detection is a way of nondestructive testing of dangerous combustible gases from sealed components or systems. Leaks can easily result from poor seals and connections, as well as from inadequate welds. Slow gas leaks from small defects or vibrations can be dangerous, expensive, frustrating, time consuming,...
E Instruments International’s gas monitoring specialists performed a forklift exhaust gas analysis and an ambient air quality analysis at a Pennsylvania warehouse in which a fleet of propane forklift trucks is operated on a daily basis. The main objectives of these tests were to investigate:
An increasingly dangerous trend in home and building Energy Audits focus solely on the “Energy Efficiency” of the building while ignoring the potential risks of sealing “IN” CO2 emissions and moisture in the home causing serious health and comfort concerns. By sealing your home to be “Air Tight” for the purpose of decreasing gas and electric bills, you could also be making our buildings TOO TIGHT. In many cases, the benefits associated with a drop of energy usage...
Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, and measure and reduce harmful emissions in the forklift engine exhuast gas.
Warehouse Optimization: Balancing Equipment Performance and Worker Safety Through Emissions Measurements and Air Quality Monitoring. Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishes and delivery trucks emit toxic gases that can have the potential to create poor indoor...
