Boosting boiler efficiency and availability through fouling management | IRRC 2018

Heat Management attended IRRC Waste to energy in Vienna Oct 1st-2nd. We presented under the title ‘Boosting boiler efficiency and availability through fouling management’. Here you can read the article that was published at the conference!

About optimizing rebuild of soot blowers

Experience has shown that more than 90% of the cleaning by a soot blower takes place during the soot blower’s initial stroke. When the soot blower is retracted, 50% of the steam is used unnecessarily at the same time as the soft ash is sintered into concrete-like deposits. By equipping each soot blower with an actuator for local control of the steam flow it is possible to:

  • Halve your steam consumption
  • Increase you production of electricity
  • Double your soot blowing power
  • Use cheaper fuel

About Infrasound cleaning

Preventive method for all dry ash deposits, in WtE boilers used in ECOs, SCRs and APHs. Typical results are:

  • Solving clogging issues
  • Reduced steam consumption of soot blowers by 70-100 %
  • Reducing wear from soot blowers or erosion due to partly blocked tube bundles/SCR elements
  • A single unit, with low maintenance, needed for a large cleaning area, such as a whole ECO

About Big Data analysis

Our unique software is used alone or together with above cleaning technologies to analyze boiler operational data, making clear where upgrades of the soot cleaning systems are most needed and quantifying the outcome. The software’s built-in regression analysis shows the relation between all operational parameters, quantifying how much a change in one parameter influences other parameters. This is helpful when optimizing the operation of the boiler.
