B3 Systems has a US Patent [US 6,694,796] for a method using direct injection or spiking of particulate matter (PM) to calibrate PM monitoring devices. B3 Systems developed this method for introducing measured amounts of your native PM into the off-gas stream to increase the PM concentration without affecting the control equipment. B3 Systems has successfully conducted over 200 PM spiking programs since 2010.
In section 8.6(4)(i) of EPA's Performance Specification 11, PM spiking is mentioned as a method for providing a range of concentrations.
On/Off Switch - The PM Spiking system has an On/Off switch if there is ever an issue or question about the PM emissions.
Efficiency - Be more efficient with on-site testing time to get the data points you really need by being able to make quick and easy set-point adjustments to the PM spiking rate and therefore changing the PM concentration in the stack.
Maximize calibration curve data - By extending the data set used in your calibration curve you also improve the correlation coefficient. This is more controlled using PM Spiking. PM Spiking allows you the ability to "reach" for the high points and see how the system responds within minutes versus hours.
Reduce retesting risk - By extending your curve and getting a higher analyzer response, it dramatically reduces the chance of exceeding the 125% limits that require retesting.
Control and Repeatability - The PM Spiking System ustilizes a PID control logic to insure that the same mass of PM is being injected for each condition.
Help your RCA in 3 years - If you are not planning for it now, then you should be. The highest analyzer response on your iniital curve defines what data points are valid in the RCA.
An automatically controlled loss-in-weight solids feeder produces a consistent mass flow rate of particulate matter. A solids eductor is used to fluidize the solids into a stream of heated air before being injected just downstream of all air pollution control devices.
Use Your Own Ash The emissivity and particle size of particulate matter affect the response of optical PM CEMS. The characteristics of the particulate matter vary from site to site. Using the ash collected from your ESP or baghouse, we can introduce known quantities of particulate matter and observe the PM CEMS response. The patented process developed by B3 Systems ensures adequate dispersion and no particle size segregation during handling.
Accurate & Precise Mass Flow Rates B3 Systems uses a loss-in-weight feeder specially designed to produce precise mass flow rates (within 2%). The mass flow rate is constantly monitored and controlled to produce consistent flow rates during each test run. The mass flow set point is easily changeable over a wide range of flow rates to produce calibration points quickly and easily at any desired concentration. The scale and mass flow rates are verified before and after each test using NIST-traceable weights.
B3 Systems can support multiple simultaneous PM spiking programs with our own people and equipment.
We currently have a full-time staff of 6 personnel with field extensive experience, 5 PM metering systems with different capacity ranges.
We have fed as low as 85 grams/hr and higher than 600 lbs/hr.
We have supported both dry scrubber and wrt scrubber applications with injection locations over 200 ft above the feeder system.
Let us show you how PM Spiking benefits your next PM CEMS or PM CPMS program.
