Which type of Dust Monitor do I need, Optical or Triboelectric?
Smoke and dust are both known as particulate matter (PM). PM can be measured via a number of different techniques, including Opacity and Triboelectric effect. Opacity is a measure of light attenuated as it crosses the stack. A proportion of the light is lost through scattering, absorption and reflection by the PM in the stack. The amount of light lost depends on the number and the size of the ...

Development of a real-time stack particulate mass monitor
Abstract Presently, particulate emissions from stacks are measured by sample and weigh methodology, which despite their status as ‘reference methods’ are often slow and sometimes not very repeatable. These methods use comparisons of before and after filter weighing to yield an average particulate concentration for a given sample period. The procedures require a great deal of care to ...

Why Use Purge Air? And What Practicalities to Consider.
Many AMETEK Land instruments use purge air, in the post I am going to explain the purpose and some of the practicalities surrounding this technology. In general, purge air is used on optical instruments such as emissions monitors and pyrometers which are mounted on industrial processes. It is important to keep the optical surfaces of such instruments clean, as contamination can affect their ...

Navigating NSPS subpart Db for boilers: a case study
Over the past year, Trinity assisted a chemical company with the permitting and installation of a new 220 MMBtu/hr package boiler. The new natural gas-fired boiler replaces coal-fired units that were installed in the 1940s. Navigating through the numerous, and at times conflicting, regulatory requirements applicable to such a unit has been challenging. With careful planning and implementation, ...
