Particulate detection technologies for preventive maintenance applications
- BHA Group, Inc., Kansas City, MO (United States)
The use of continuous monitoring to ensure ongoing compliance with particulate emissions standards is common practice in most parts of the world. Recently proposed standards by the US Environmental Protection Agency (EPA) are intended to use particulate monitoring as a surrogate technique for the compliance monitoring of Hazardous Air Pollutants (HAPs). This approach is based on the lack of available technologies for measuring HAPs, as well as the availability of cost-effective, reliable, low maintenance particulate monitors available today. Many types of particulate monitoring instruments are now available, but to date, all have been based on two basic measurement principles--optical or light attenuation (opacity) and contact electrification (triboelectric). Long-term exposure to problems with these methods led BHA engineers to refine a variation of the optical light attenuation method for their CPM continuous particulate monitoring product line. This technique of monitoring is known as received light modulation or scintillation.
