Reliable level technology for coal fired power stations

There are several locations where coal fired power plants measure level of coal. Integral aspect of the coal level measurements, so as other solids and bulk materials, is dust. The best solution, immune to dust are accoustic level transmitters Sultan with temperature compensation and self-cleaning sensors.

Applications problem

Coal fired power plants require reliable monitoring of the following level applications for proper coal feeding process at

  • raw coal bunker
  • boiler coal bunker
  • conveyour belts
  • shuttle / discharge wagon positioning control

Solution

  1. Raw Coal Bunker: The raw coal bunker was 25 meters (82 ft) high. The level transmitter has to control the shuttle conveyor.
  2. Boiler Coal Bunker: The boiler bunker was 20 meters (65 ft) high. The level transmitter was to control the shuttle conveyer. For application 1 and 2 we provided low frequency 10 kHz loop powered transmitters to overcome dust, rat holing etc.
  3. Coal on Belt Detector: Monitoring coal on the conveyor belt. Range 1-5 meters (5 ft). For application 3 we provided 20 kHz integral transmitter to provide reliable profile height on conveyors.
  4. Shuttle Positioning Transmitter: The maximum range was 50 meters (164 ft) for the shuttle conveyor and 195 meters (640 ft) for the coal discharge wagons. For application 4 we provided our 20 kHz positioning transmitter and for the discharge wagons we provided our 5 kHz positioning transmitter.

Features

  • measurement immunity to dust and moisture
  • self-cleaning sensor
  • effective range up to 180 m
  • measurement temperature compensation
  • integral and remote versions up to 1000 m
  • manufacturer's application guarantee

Benefits

  • reliable level measurement
  • contactless measurement guarantees no sensor damages caused by material
  • maintenance free sensor
  • real time, online process visualization and control
