Strategic tools towards a sustainable use of biomass for low carbon domestic heating

WPT4

Workpackage "Sustainable, technical and financial solutions for BB" investigates the best technological solutions for small scale biomass combustion for domestic heating production and the financial tools that can foster a technological change in the Alpine Region (AR). From the state of the art of the actual economic and financial tools related to BB in the Alpine Region (WPT1) and from the awareness raising activities (WPT2) that will foster the use of the mobile app (WPT3), WPT4 outputs will help the implementation of the low carbon policies (WPT5).

    

D.T4.1.1 - Booklet on auxiliaries to be coupled to biomass combustion appliances and energy savings methods

Heat delivery by biomass systems is in many ways more environmentally friendly, whilst also a good economic solution. This is especially true in the case of changing from the oil heating to a comparably comfortable pellet heating system, which can quickly lead to a return on investment. In order to reduce the heat demand and therefore energy costs in the long run, the heat losses through the building envelope must be minimized. This is achieved by insulation of the exterior wall, roof or top floor ceiling and the basement ceiling. With regards to the windows thermal insulation glazing has priority This booklet focuses on aspects which are of major impact on overall system efficiency of biomass use for heating purposes in dwellings. First, the critical aspects for dimensioning biomass burning systems are defined. Secondly, the factors impacting heat distribution are explained followed by different types of heating systems. In the end the current label regulations in the EU are presented. 

    

D.T4.1.2 - Booklet on pollution abatement systems

The combustion of biomass causes emissions of harmful flue gases and particulate matter into the atmosphere, which is mainly due to the incomplete combustion of these materials. When it comes to increasing efficiencies and reducing pollution, non-technical measures such as consumer behaviour and fuel quality play a significant role. However, those primary measures are not enough to reduce the particulate matter emissions sufficiently. End-of-pipe technologies are used to decrease the amount of particulate matter released into the atmosphere. This deliverable focuses solely on secondary measures and aims to explain the most common abatement technologies.

    

D.T4.1.3 - Booklet on experimental results

Before a biomass boiler or stove is released to the market the manufacturers have to prove, that their appliance fulfils the legal emission limits. This is achieved with standardised type tests. However, these testing conditions do not fully depict the actual operating conditions. In reality, aspects such as fuel quality or consumer behaviour have a significant impact on the amount of emissions released during operation. This booklet focuses on experimental test results on biomass furnaces that were conducted under real operating conditions and the comparison of those emissions to the type test results. The first part of the booklet deals with existing literature and publications of such studies whereas the second part aims to show experimental results from certification reports. Report is especially focused on the impact of fuel quality on the formation of emissions.

   

D.T4.3.1 - Report “Towards financially sound clean BB in the Alpine Region”

“How can we develop financial incentives approaches that promote in a most efficient way the use of cleaner technologies and a sustainable use of chimneys, oven and other private household wood low-technology based heating systems?” This question is asked by policy makers throughout the entire Alpine Region. Actually there exists no clear scientific framework to analysis the efficiency of regulations and financial support instruments in the context of clean biomass burning. Further on policy makers may ask if there is not a process or approach that could support the systematic development of such regulations and financial instruments. This question is part of WPT5 in this BB-Clean Project. Taking these points into account we defined in our project plan to identify new innovative approaches to financial support schemes. These support approaches can be analysed in the future using the ecological and economic efficiency analyses tool (EEA-Tool) to evaluate the most appropriate financial instruments in the alpine region (A.T1.4). In this report we summed up the steps and results.
