Analyzing Vibration to Evaluate Sootblower Performance

ITM stake holders, we have recently received good news from the US Patent Office. They have recently allowed claims relating to the use of vibration measuring devices to evaluate the operation of a sootblower (US20190041201A1). This allowance strengthens the protection of the sootblower health and fouling detection features of ITM’s Sootblower Fouling Detection (SFD) Technology.

Additional Claims: “A method of evaluating an operation of a sootblower in a boiler system, the method comprising: operating a sootblower having a rotating lance tube; measuring a vibration in the boiler system caused by the operation of the sootblower, wherein the vibration is measured with a vibration measuring device; and analyzing the measured vibration to evaluate the operation of the sootblower.”

US Patent #: US20190041201A1

Silo Load Monitoring

Plant operators need to continuously measure bulk material levels/weight to make sure their processes are running safely, efficiently and without any bottlenecks. Measuring these levels allows operators to automate vessel filling/emptying logistics or verify that a process is using the right amount of material.

How do you measure bulk material levels/weights in silos and hoppers?

There are a variety of bulk material level/weight monitoring sensors in the market. These sensors include distance measuring devices like laser, ultrasonic, and radar; or weight measuring devices like load cells and strain gauges. Our engineers prefer to implement strain gauge based solutions because they are very accurate and do not require structural modification.

For these solutions, our engineers identify the silo/hopper load paths and our technicians install strain gauges at these locations. By calibrating the strain gauge sensors to load and summing the load data for all load paths, we can accurately measure the total weight of the bulk material.

A typical silo monitoring system consists of weatherproofed strain gauges for each silo leg and a National Instruments (NI) CompactRIO embedded controller for inputs, calibration, and outputs housed in a stainless steel enclosure.
