Process Particle Counter
The Process Metrix PPC (Process Particle Counter) is designed to provide in-situ measurements of airborne particles for low concentration (< 5 gm/m3) industrial gas/particle flow systems. This sensor is capable of providing particle concentration, size distribution, and velocity information in hostile environments. PPC can (when enclosed in a water-jacketed probe) measure in gas temperatures up to 1400°C or high pressures (up to 100 Bar) in extractive mode. Measurements at combined high temperature and pressure (400°C and 20 Bar) have also been achieved.
Industry Applications:
- Gas Turbines
- Turbo-expanders
- Filtration Efficiency measurements
- Stack and Duct monitoring (CEMs)
Industries:
- Petroleum refineries
- Gas Turbines
- Gas Distribution Systems
- Cement, Steel
- Foundry
- Aluminum
- Boilers
- Powder Production/collection
- Pulp and Paper
- Powder milling and Processing
- Laboratory and Field Research
- Filter Testing, and more
Particle Size and Concentration Measurements for Real-Time Process Applications
The graph below shows recent time history measurements of a power boiler baghouse performance, showing concentration, mean size, and velocity as a function of time. Note that the peak particle concentration increases by a factor of 10 during the periodic backflush to remove the dustcake. The mean particle size also increases indicating a period where filtration is poor. This information will allow the user to optimize bag-pulse timing to maximize filtration, bag lifetime, and other process parameters that impact total cost of operations.
Figure 1. Particle size and concentration measurements made with a PPC instrument in a bag house. Periodic increases in concentration and size due to bag house "pulsing" needed to remove particulate duskcake.
