SMART Gauge Sensor
Operating Principle
- Installed on the hanging tubes outside the boiler and detect changes in weight of the ash deposits building up on the heat exchanger surfaces by means of strain gauges
- Increasing deposits result in increase in weight
- This localises areas of heavy deposits
- The number and positioning of the sensors depends on the boiler geometry as well as the layout of the heating surfaces and the number and position of boiler-cleaning equipment
Technical Summary
The SMART Gauge Sensor is designed to directly measure the weight of ash deposits on heat exchanger bundles, based on strain gauge technology.
- General Application Area: Superheater, Reheater, Economiser
- Key Industries: Power Generation, Waste-to-Energy, Biomass, Oil & Gas, Other Industrial Processes
Key Features
- For special applications and boiler design, high temperature sensors up to 600 °C are available
- By using a certain amount of SMART Gauge Sensors, a measuring grid is created to cover the complete cross section of the boiler
Product Benefits
- By detecting the fouling situation on the heat exchanger bundles, demand-oriented, selective and automatic on-load cleaning can be activated
- Prevention of uncontrollable deposits
- Improved heat absorption in the convective part
- More flexibility in the use of different fuel qualities and compositions
- Reduced consumption of cleaning media
- Lower influence on process due to targeted and reduced convective part cleaning
