Costs of reduction techniques for LCP

A methodology for cost estimation of abatement options of SO2, NOx and TSP (Total Suspended Particulates) for Large Combustion Plants (LCP) with a thermal capacity of more than 50 MWth, is developed by TFTEI.

It aims to provide technical and cost data for the following reduction techniques applied on large combustion plants using coal, heavy fuel oil and natural gas as well as biomass in co-combustion with coal.

Only boilers are considered (gas turbines could be examined in the next steps).

Reduction techniques considered are the following ones:

  • NOx: primary measures, SNCR (Selective Non Catalytic Reduction) and SCR (Selective Catalytic Reduction),
  • TSP: electrostatic precipitator (ESP) and fabric filter (FF),
  • SO2: wet flue gas desulphurisation with limestone forced oxidation (LSFO – Limestone Forced Oxidation), semi dry (LSD - Lime Spray Dryer) and dry desulphurisation (DSI - Duct Sorbent Injection, using lime and sodium bicarbonate).

Costs are estimated for different regulatory objectives in term of ELVs (Emission Limit Values) assuming one boiler or a group of boiler linked to a chimney.

To assist the TFTEI Technical Secretariat to develop the methodology for cost estimations of reduction techniques for LCP, a working group has been established.

Participants are:

  • Jean-Guy Bartaire (EGTEI/TFTEI co-chair);
  • Richard Brandwood (E’on, United Kingdom);
  • Nicolas Caraman (EDF, France);
  • David Cooling (E’on, United Kingdom);
  • Ivan Jankov (European Commission);
  • Daniel Ladang (Total/CEFIC, Belgium);
  • Hélène Lavray (Eurelectric, Belgium);
  • Tiziano Pignatelli (EGTEI/TFTEI co-chair);
  • Koen Smekens, Arjan PLOMP (ECN, The Netherlands);
  • Jonathan Van Der Kamp, (EIFER, Germany).

Other experts contributed to delivering information to the TFTEI Technical Secretariat: the French group from the Chemical industry Union on coal boilers (chaired by Michel Monzain); Frans Van Aart (KEMA) in The Netherlands, manufacturers of abatement equipment (Hamon, Solvair, GE Air Filtration, CNIM), operators of combustion plants.

We apologise for not citing other experts who very kindly contributed to delivering information.

An EXCEL tool is available ERICCa_LCP (Emission Reduction Investment and Cost Calculation) associated with a manual for using the tool and a description of the methodology.
