IRRC 2018

Heat Management presenting at IRRC 2018 in Vienna

Heat Management will be at IRRC in Vienna Oct 1st-2nd, presenting on Oct 2nd at 14.00 under the title ‘Boosting boiler efficiency and availability through fouling management’.

For waste incinerators large savings are possible by optimizing the soot blowing system. Heat Management’s approach is to use one or several of a unique set of tools:

  • Preventive low frequency (infrasound) acoustic cleaning Typically used in ECO, SCR and APH.
  • Optimizing rebuild of steam soot blowers for soot blowing more often or faster or for reducing steam consumption by local control of the steam supply to each sootblower. Enabling overlapping sootblowing which enables increasing the number of soot blower starts in critical areas.
  • Big data operation analysis for detailed study of the operational parameters of the boiler.
  • CFD flow analysis for studying e.g problems related to uneven distribution of flue gas flow.

About optimizing rebuild of sootblowers

Experience has shown that more than 90% of the cleaning by a sootblower takes place during the sootblower’s initial stroke. When the sootblower 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 sootblower 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 sootblowing 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 sootblowers by 70-100 %
• Reducing wear from sootblowers 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.

About IRRC

The IRRC Waste-to-Energy forum has long since established itself as one of the leading conferences in the Energy-from-Waste sector. This event is a good opportunity to meet European waste-to-energy experts and decision makers. The exchange of experiences, ideas, and concepts will give impulses for cooperation and is going to promote development particularly in the new EU-member states.
