Electricity consumers with time flexibility, such as plug-in electric vehicle (PEVs) users that adapt consumption to current generation, can increase their self-consumption rate (SCR) and obtain a price advantage. Renewable energy community (REC) members without their own home charging station (HCS) require charging stations (CS) that are either op...
Firewood stoves are widespread and popular for renewable heat supply in Europe. Several new technological measures have been developed recently that aim at improving the appliance performance in terms of emissions and efficiency. In order to support the trend towards “(nearly) zero-emissions technologies”, the objective of this study was to provide...
As illustrated by the development of stock numbers and market volumes, pellet stoves become more and more popular as renewable and sustainable heating technology in Europe. Compared to manually operated firewood room heating appliances pellet stoves are featured with an automatic fuel supply into the combustion chamber and offer various options for...
- Overveiw about different test methods for evaluation of emissions and thermal efficiency of firewood and pellet stoves.
- Presentation of (new) test concepts that focus on evaluation of appliances close to real-life operation.
Biomass combustion is a major contributor to ambient air pollution. Thus, knowing the real life emissions of biomass heating systems is crucial. Within the project Clean Air by biomass a field measurement campaign was conducted. 15 biomass heating appliances were tested in households at the end user according to their usual operation. Emission fact...
Emissions from domestic wood heating appliances in the field are increased in comparison to their official type test results. In the Clean Air by biomass project a field campaign with 13 wood heating appliances was conducted. Thereby, gaseous and particulate emissions as well as thermal efficiency were determined. Moreover, technological and non-te...
Residential wood combustion is linked with a significant extent of emissions of polycyclic aromatic hydrocarbons (PAHs), which represent highly toxic, semi-volatile pollutants. The use of catalysts reveals an effective measure to reduce emissions, especially gaseous flue gas compounds (carbon monoxide - CO and organic gaseous compounds - OGC). Thei...
Biomass room heating appliances are the most commonly used technology for providing renewable heat in residential buildings. They are categorized in different technologies by harmonized European standards (e.g. firewood roomheaters – EN 13240, insets and open fireplaces – EN 13229, biomass cookers – EN 12815, slow heat release appliances – EN 15250...
Catalytic systems integrated in firewood stoves represent a secondary measure for emission reduction. This study evaluates the impact on emissions of two types of honeycomb catalysts integrated in different firewood stoves. The tests were conducted under real-life related testing conditions. The pressure drop induced by the catalyst's carrier geome...
In Europe, the official type test method (oTT) according to the standard EN 13240 evaluates the emissions and thermal efficiency of firewood roomheaters only under optimal conditions, i.e. heated-up and at nominal load. In this study a novel test method, called “beReal”, is presented which was developed to reflect real-life operation within the tes...
Catalytic systems integrated in firewood stoves represent a potential secondary measure for emission reduction. However, the evaluation of catalytic efficiency is challenging since measurements, especially for PM emissions, upstream an integrated catalyst are not possible. Therefore, a special test facility, called “DemoCat”, was constructed which...
Critical heating operating conditions, as emulated in the safety test series, showed that temperatures
below 400 °C at the integrated catalysts result in deposited agglomerations on the flow cross-section
area of the catalyst's surface and in the risk of increased pressure drops. The deposited material of
safety tests consisted predominantly of car...
Wood pellet combustion for heating is increasing in importance in Europe. However, the most commonly used heating appliances such as wood pellet stoves are responsible for emissions which could negatively affect human health. The emissions quality of pellet stoves is influenced by pellet properties and combustion phase characteristics. The goal of...
Firewood roomheaters are popular, widespread and important for reaching European CO2 emission targets. Since they contribute significantly to local air pollution, they have to be optimized towards minimal emission release, especially in real-life operation. Draught conditions and user behavior, particularly the ignition technique, significantly aff...
This study analyses the emission factors of two firewood room heaters under testing conditions which emulate real life operation. A 6.5 kW stove with low heat storage capacity and high leakage rate (stove A) is compared with an 8 kW air-tight stove with high heat storage capacity (stove B). Thermal efficiency, carbon monoxide (CO) and organic gaseo...
Wood combustion is the main renewable heating source for European households and responsible for a
large portion of the particle matter in the atmosphere. Firewood operated small-scale residential wood
combustion units such as firewood stoves and tiled stoves are the most widespread wood combustion
appliances in households. Next to purely technolog...
Firewood heaters like firewood roomheaters, tiled stoves and residential biomass cookers are commonly used for supplying the residences with renewable heat. However, these kinds of appliances were identified as responsible for relevant amounts of gaseous CO and OGC as well as particulate emissions causing negative health effects. Beside technologic...
Development of test procedures for pellet stoves
In this study a bulk oxidation catalyst was characterized by using a new developed laboratory test reactor which provides test conditions which are similar to application conditions in a small-scale firewood stove in terms of temperature range, gas velocity and behaviour of the catalyst bed. The results show a beginning conversion of carbon monoxid...
