\nBACKGROUND AND AIMS <\/span><\/h1>\n


\nFireplaces and wood log stoves that burn wood in a suboptimal manner are an important source of particle emissions around the world. By phasing out polluting woodstoves and introducing better stoves, improving stove installations and educating stove users, large emission reductions can be achieved. Moreover, there is evidence that the health impacts of fine particles from well operated biomass combustion devices is much less harmful than that of suboptimally operated devices.As biomass heating consitutes an important option to contribute to renewable energy production in many countries, it is important to recognise the differences in environmental impacts and societal consequences for different types of combustion systems, and take appropriate policy measures. <\/span><\/span><\/span><\/p>\n


\nThis T32 organised expert workshop on biomass combustion generated particles took place on 14 June 2016 as integral part of the 20th Conference on Combustion Generated Nanaoparticles . See http:\/\/nanoparticles.ch<\/a> for more information and the other presentations offered at the conference. <\/span><\/span><\/span><\/p>\n

RESULTS<\/span><\/h1>\n


\nThe workshop showed that there is an enormous difference in the relevance of biomass combustion particles between well designed and operated stoves and boilers on the one hand, and inappropriately designed or used devices. While in a modern and automatically operated biomass boiler with state of the art flue gas cleaning, particle formation may be primarly in the form of inorganic components, which are then also almost fully captured in an electrostatic precitpitator or baghouse filter, older biomass stoves and boilers that do not avail of proper flue gas cleaning devices and are inappropriately used, may cause significant particle emissions with also
\ngreater toxicity. <\/span><\/span><\/span><\/p>\n

\nPOLICY STATEMENT ON THE NEED FOR REDUCTION OF PARTICLE EMISSIONS<\/span><\/h1>\n


\nBased on the results of the workshop,
\nTask 32 released the following statement. <\/span><\/span><\/span><\/p>\n\n\n\n\n
\n


\nBiomass is used as a renewable energy carrier to substitute fossil fuels for heat and power production.
\nModern biomass boilers that comply with today\u2019s emission limits and that are operated
\nappropriately have typically a low environmental impact. Biomass can therefore be used in an
\nenvironmentally friendly way, if the necessary requirements are met. There are, however, undesired
\nsituations which can lead to non-ideal conditions.
\nThis can potentially cause a high negative impact to the air quality
\nwith an increased contribution to volatile organic compounds (VOC) and
\ninhalable particulate matter in the size range smaller than 10
\nmicrometres (PM10) in the ambient air. <\/span><\/span><\/p>\n

From the
\nactivities of various research groups represented in the International
\nEnergy Agency (IEA) Bioenergy Task 32 and at the ETH Conference on
\nCombustion Generated Nanoparticles in June 2016 [1\u20135] it is concluded,
\nthat the following topics need to be supported to avoid a high impact of
\nbiomass combustion to ambient air quality: <\/span><\/span><\/p>\n

 <\/p>\n

    \n
  1. The operation of the combustion devices has a strong influence on the
    \nair pollutant emissions. This is true for all devices, however most
    \nrelevant for manually operated boilers and stoves. One important
    \nissue is the use of an appropriate fuel with respect to fuel
    \nmoisture, size, and ash content for the dedicated combustion device.
    \nFurthermore, an appropriate ignition is required. Investigations
    \nshow that an \u201cignition from the top\u201d is favourable for many
    \nconventional wood stoves. In addition, the amount of wood for one
    \nbatch needs to be adjusted to the size of the combustion chamber.
    \nFinally, sufficient combustion air, although not exceeding a
    \nreasonable amount, needs to be supplied during the combustion phase.<\/li>\n
  2. Standardisation of biomass fuels, combustion devices, type-tests,
    \nand measurement technologies can assist a target-oriented
    \ndevelopment to further improve the quality of biomass combustion
    \napplications and ensure a low impact on air quality. For the
    \ndefinition of new standards, test conditions which represent a
    \nreal-life operation should be considered.<\/li>\n
  3. Design
    \nguidelines and quality management for the planning and
    \nimplementation of biomass combustion plants can assist an
    \nappropriate layout and dimensioning as a pre-condition for an ideal
    \noperation of the combustion and the flue gas cleaning. Furthermore,
    \nplant monitoring can assist an on-going optimisation of the
    \noperation mode and an adaptation on varying requirements and fuel
    \nparameters.<\/li>\n
  4. An
    \ninternational exchange of experience between all stakeholders from
    \nresearch, industry, energy economics, and national authorities can
    \nassist this process. Nevertheless, the enforcement of regulations on
    \nenergy standards and on air quality plays an important role and
    \nneeds to be followed also on a national basis.<\/li>\n<\/ol>\n
