Incineration


PCME provide a full range of robust particulate monitoring systems suitable for the incineration industry, and have considerable experience with the specific emission monitoring environments in the following processes:

  • Municipal waste incineration
  • Co-incineration processes
  • Chemical and industrial waste incineration
  • Medical waste incineration
  • Sewage sludge incineration
  • Cremation

PCME’s involvement with the incineration industry includes supporting plant to meet particulate emissions control obligations, much of which is tightly regulated and requires high performance instrumentation with high quality assurance features for compliance reporting. For example, in Europe PCME provide QAL1 approved systems to plant falling under the Waste Incineration Directive (WID) where monitoring solutions must meet the quality assurance definitions in EN 13284-2, for EN 14181 compliance. Similarly, PCME provide PS-11 compliant PM CEM solutions to US EPA regulated plant, particularly Title 40 CFR Part 60 regulated plant which includes a range of incineration processes.

In addition to the importance of regulatory compliance, the control and treatment of emissions from incineration processes represents a significant proportion of overall costs, and therefore quality data from emissions monitoring technology can provide valuable feedback on abatement plant performance to enable plant operators to implement greater efficiency and control over plant operation. This is particularly relevant for waste-to-energy (co-incineration) plant and energy recovery systems where accurate incineration efficiency data translates into increases in energy production.

Particulate emissions from incineration plant primarily consist of entrained fine ash in the flue gas, with variable amounts of organic and inorganic substances depending on the specific incineration process and reaction balance. Particulate emissions to air from incineration processes are typically reduced to as low as <0.05mg/m3 to 15mg/m3, by means of high performance bag filters alone, or often bag filters in combination with electrostatic precipitators, wet scrubbers and occasionally cyclone filters. Incineration processes often use ‘pre-dedusting’ plant upstream of the main flue gas treatment process, which allows collection of recyclable material in some cases, and reduces the quantity or toxicity of Flue Gas Treatment (FGT) residues in others while reducing load on downstream FGT.
