MEASUREMENT & MODELLING OF FINE PARTICULATE EMISSIONS FROM WOOD-BURNING BIOMASS BOILERS

This project aims to assess the impact of wood-burning biomass boilers on fine particulate matter (PM) levels in urban areas. Grants for biomass boilers are provided as part of renewable targets, but smoke control areas do not cover fine PM emissions. This study will measure emissions from a range of biomass boilers and model their cumulative impact on urban air quality.

  1. MEASUREMENT & MODELLING OF FINE PARTICULATE EMISSIONS FROM WOOD-BURNING BIOMASS BOILERS OVERVIEW OF PROJECT

  2. RATIONALE CONCERNS EXPRESSED TO SG THAT IN URBAN AREAS BIOMASS BOILERS MAY HAVE A CUMULATIVE IMPACT ON PM LEVELS SG (ALONG WITH REST OF UK) PROVIDES GRANTS FOR BIOMASS BOILERS AS PART OF RENEWABLES TARGETS

  3. SMOKE CONTROL AREAS DO NOT COVER FINE PM HENCE NO REQUIREMENT TO PROVIDE INFORMATION ON EMISSIONS FROM BIOMASS BOILERS • NUMBER OF LAs HAVE URBAN AREAS CLOSE TO DECLARING AQMA FOR PARTICULATES • NO DATA AVAILABLE FOR FINE PM EMISSIONS AND THE CUMULKATIVE IMPACT OF THESE FROM BIOMASS BOILERS IN URBAN AREAS • GREATER LONDON AUTHORITY WERE CONDUCTING A SIMILAR STUDY IN RESPONSE TO THIS INFORMATION GAP BUT WITHOUT MEASURING EMISSIONS

  4. A RANGE OF BIOMASS BOILERS ARE TO BE TESTED FOR PM EMISSIONS – THE BOILERS WILL REFLECT THOSE CURENTLY IN USE IN SCOTLAND • PM10 AND 2.5 TO MEASURED AS IMPACTS ON URBAN AIR QUALITY CLOSELY TIED TO LIMIT VALUES FOR THESE 2 FRACTIONS • MODELLING THE IMPACT OF MEASURED LEVELS OF EMISSIONS FROM A NUMBER OF BOILERS WILL PROVIDE AN ESTIMATE OF THE CUMULATIVE IMPACT ON PM LOADING FOR URBAN AREAS • MONITORING UNDERWAY AND MODELLING TO BE UNDERTAKEN IN APRIL – PROJECT DUE TO COMPLETE MAY 2008
