Operating Principle

  • The division of the boiler into zones represents an important basis for the precise detection of the position of the slagging within the heating surface
  • Analyses are conducted for each zone to determine the respective status of slagging
  • The measured heat fluxes and/or surface temperatures are converted into coordinates which represent the position and intensity of the slagging
  • Areas of the boiler which may not be cleaned, such as the burner and secondary air feeds, are taken into account in zone distribution
  • On this demand-oriented basis, SMART Furnace generates selective cleaning requirements Selectable “closed loop” mode for assessing a conducted cleaning operation by evaluating direct sensor measurement values

Technical Summary

SMART Furnace HFX is an intelligent on-load furnace cleaning system

It uses sensor based information to identify the slagging position and thus hotspots in the different locations in the furnaces. By doing so, it is possible to react on inhomogeneous slagging caused by different boiler loads and changing fuel qualities.

  • For the determination of the slagging situation, the following sensors are available:  SMART Flux Sensor, SMART Membrane Sensor and SMART Multi-Point Sensor
  • General Application Area: Furnace
  • Key Industries: Power Generation, Waste-to-Energy, Biomass, Other Industrial Processes

Key Features

  • Identification of slagging hotspots in the furnace and selective cleaning of those hotspots only
  • Fully automatic on-load control of the cleaning activities and thus ongoing automatic optimisation of the cleaning strategy
  • Adaption of cleaning intensity according to the current measured cleanliness situation, depending on the used cleaning equipment
  • Optimal usage of the cleaning media – cleaning activities will be reduced to the necessary amount by targeting cleaning

Product Benefits

  • Demand-orientated, selective and automatic on-load furnace cleaning to prevent uncontrollable deposits
  • Improved heat absorption in the evaporator
  • Reduced Furnace Exit Gas Temperature (FEGT)
  • More flexibility in the use of different fuel qualities and compositions
  • Lower influence on process due to targeted and reduced furnace cleaning
  • Structured and easy-to-follow visualisation of the measured values in the evaporator
  • Continuous monitoring and analysis of the thermal strain on the evaporator wall heating surfaces
