Extractive TDL Online HCl Analyzer vs. In-Situ Wall-Mounted TDL HCl Monitoring System: Which One Should Waste-to-Energy Plants Choose

 Hydrogen chloride (HCl) monitoring in waste-to-energy plants is challenging because hot, wet, dusty flue gas can affect sampling, response time, and measurement stability. Choosing the right TDLAS architecture helps plants obtain reliable continuous HCl data.

For waste-to-energy plants, both extractive and in-situ TDLAS can provide continuous HCl monitoring. Extractive systems transport a heated sample to an gas analyzer, while in-situ systems measure HCl directly across the flue-gas path. The better choice depends on gas conditions, installation access, measurement requirements, and CEMS design.

Understanding Dust Monitors: Working Principles and Advantages

Image
 Dust, whether visible or microscopic, is a common environmental pollutant that can have significant implications for both human health and the environment. To effectively manage and mitigate the impact of dust, various monitoring techniques and instruments have been developed. One such instrument is a dust monitor. In this blog, we will explore what a dust monitor is, how it works, and the advantages of using it. What is a Dust Monitor? A dust monitor , also known as a particulate matter monitor or particle counter, is a specialized instrument designed to quantify and monitor the concentration of airborne dust particles in the atmosphere. These particles can be of various sizes, ranging from large, visible particles to ultrafine particles that are often too small to be seen with the naked eye. Working of a Dust Monitor The working principle of a dust monitor involves the following components and processes: Sampling Mechanism: Dust monitors are equipped with a sampling system, whi...
