The report assesses the typical quantity and composition of aerosols emitted from biomass fired stoves and boilers, and reviews the results of recent R&amp;D projects in which the health impacts were evaulated.<\/p>\n<p>This report summarises the current knowledge on the health relevance of combustion generated PM, describes the mechanisms which can cause PM in biomass combustion, describes different particle types, and provides infor\u00admation on measures to reduce PM from biomass combustion. It is important to distinguish carbona\u00adceous and inorganic pollutants as well as primary and secondary aerosols. Organic pollutants are particularly relevant to residential biomass combustion and can be avoided at near-complete com\u00adbustion conditions. Particles resulting from incomplete combustion in manual devices exhibit a high cytotoxicity, while particles from properly operated automated biomass boilers and furnaces are mainly inorganic (derived from ash constituents in the biomass) and exhibit significantly lower or even unde\u00adtectable cytotoxicity. In addition, inorganic particles can be removed effectively by air pollution con\u00adtrol equipment such as electrostatic precipitators or fabric filters. In summary, biomass can play an im\u00adportant role in future energy supply in an environmentally friendly manner through im\u00adple\u00admen\u00adta\u00adtion of state-of-the-art combustion devices and their appropriate operation.<\/p>\n<p><a href=\"https:\/\/task32.ieabioenergy.com\/publications\/aerosols-biomass-combustion-technical-report-thomas-nussbaumer-2017\/\">Aerosols from biomass combustion &#8211; Technical report, Thomas Nussbaumer, IEA Bioenergy Task 32, 2017<\/a><\/p>\n<hr \/>\n<p><b>Workshop on new emission measurement methods, 19 January 2017<\/b><\/p>\n<p>With existing test methods for biomass boilers and stoves, the emissions are tested under stationary and optimal test conditions.

This report shows that the firing and co-firing of biomass as\u00a0a replacement for coal in large pulverised coal boilers can be a very attractive option for the utilisation of biomass materials for power production, and for the delivery of renewable energy.<\/p>\n<p>The key technical options for the conversion of large pulverised coal boilers to the firing and co-firing of biomass have all been successfully demonstrated, principally in projects in Northern Europe, over the past 10-15 years or so. A number of the plants converted to\u00a0biomass firing and co-firing are currently in operation, and there are a small number of further conversion projects currently in the proposal stage.<\/p>\n<p>The storage and handling of the biomass materials, and particularly the tendency of the biomass to generate significant dust levels, have presented the most significant problems. It is fair to say, however, that the fuel suppliers and the materials handling equipment supply industry have learned many lessons over the past few years, and that the\u00a0solutions currently being offered for biomass projects represent a significant improvement over previous practice.<\/p>\n<p>The case\u00a0studies and country reports show that through the years, a great experience has been gained with biomass cofiring in various types\u00a0of power plants and with various types of biomass fuels.
