Since the 20th century regulations have been approved to help control different types of air pollution predominantly from smoke and for odor control. While the visual impact was a first concern, emission limits were soon expressed in terms of opacity. The darkness of stack gases are measured with opacity measurement equipment to detail the amount of dust and exhaust gases that are emitted. And opacity monitor is the perfect equipment that uses light transmission techniques to measure the actual visible opacity of gases within a stack or duct. The technology itself uses a high intensity beam of light that’s projected across the stack. Any smoke, dust or particulate that is present attenuates the transmitted light and can decrease in intensity, all due to the absorption as well as the scattering, and is measured.
The Advantages of an Opacity System
An opacity system has the advantage of not letting other gases interfere with its capabilities. Currently opacity monitors come in two types; double and single pass. A single pass monitor has a transmitter and receiver arrangement that uses a light beam that is emitted from the transmitter that passes across the stack to its receiver. A double pass monitor system has a folded beam transceiver and reflector arrangement that allows the light beam to be emitted from the transceiver that passes across the duct to the reflector, then returns the beam to the transceiver.
Utilize a Cost-Effective Solution
Opacity monitors are cost-effective solution that help you meet specific monitoring requirements. They are suitable for many different types of applications including long past links. Different types of systems will work for different applications, so it is important that you speak with manufacturing specialists to help you choose the right monitor for your applications.
The problem of global warming is extremely evident in today’s world. With the rapid growth of industries and cars on the road, the emission of greenhouse gases is on the rise. But these are not the only source of greenhouse gases in the environment.
There are several gases that engulf us, and the atmosphere contains these in differing concentrations. While we need some of these gases for survival, they may pose several risks once their concentration exceeds a certain threshold. In most cases, the higher levels of many of these gases may not be good for the environment although the effect may not always be toxic. These are stack gases which are gases leaving boilers, furnaces, and fireplaces (steam generators) post combustion.
In the industrial business, some companies require O2 Analyzer which provides accurate measurement of the excess oxygen remaining in the flue gases coming from any combustion process. Optimal combustion efficiency is achieved by maintaining the ideal level of oxygen in the flue gases coming from these processes and lowest emission levels of CO, CO2 and NO× are achieved. Designed to integrate with processes and conditions. Bhoomi’s oxygen analyzer is designed with customer ease-of-use in mind. With no moving parts or sampling apparatus the analyzer is extremely reliable with oxygen probe that requires no maintenance.
Where analysis for NOx and SOx are concerned you need a quality SOx NOx analyzer. Such analyzers are used to measure high concentrations of total oxides of sulfuric (SOx) and nitrogen (NOx). You can expect excellent reliability and sensitivity when using an analyzer with a gas sample accumulator and a single measurement channel that can provide precise measurements. Some units may also provide advanced signal processing for continuous measurement of both oxides. This helps determine those levels of concentration so that they can be corrected for fluctuation pertaining to flow rate, gas pressure, gas temperature and the gases converter efficiency.
