The phenomenon of off-gassing from wood pellets during storage has been the cause several, in some cases fatal, accidents due to toxic atmospheres storages. To optimize safety measures nature responsible processes needs be clarified. In this study impact O2 availability, which is a decisive factor for presumed oxidation fatty acids, pointed out. Off-gassing rates CO, CO2, VOC, and CH4 at relatively constant levels approximately 35%, 20%, <1% over period 20 d 295 K were investigated. For...
Pellet boilers need auxiliary electrical power to provide CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 </sub> -balanced heat in a comfortable and environment-friendly way. The idea is produce this some extra electricity within the furnace order save resources gain operation reliability independency. Thermoelectric generators (TEGs) allow direct conversion of power. They have advantage long maintenance-free durability noiseless without...
The temperature-dependent release of inorganic elements is the first step main formation pathway particle emissions in automatically fired biomass burners. To investigate this step, a residential pellet boiler with an underfeed-burner was equipped direct firebed cooling. This test setup enabled decreased temperatures without affecting further parameters like air flow rates or oxygen content firebed. A reduction PM1-fraction at activated cooling found by impactor measurement and optical...
Slag is related to the melting properties of ash and affected by both chemical composition fuel combustion parameters. Chemical analysis slag from fixed bed phosphorus-poor biomass show that main constituents are Si, Ca, K, O (and some Mg, Al, Na), which indicates consists different silicates. Earlier research also points out viscosity fraction melts, as crucial parameters for formation. To authors' knowledge, very few papers published this day discuss slagging problems pelletized fuels...
Wood pellets have been reported to emit toxic gaseous emissions during transport and storage. Carbon monoxide (CO) emission, due the high toxicity of gas possibility it being present at levels, is most imminent threat be considered before entering a pellet storage facility. For small-scale (<30 tons capacity) residential facilities, ventilation, preferably natural ventilation utilizing already existing openings, has become favored solution overcome problem CO concentrations. However, there...
Residential wood combustion is linked to a significant extent of emissions polycyclic aromatic hydrocarbons (PAHs), which represent highly toxic, semivolatile pollutants. The use catalysts reveals an effective measure reduce emissions, especially gaseous flue gas compounds (carbon monoxide (CO) and organic (OGC)). Their effect on toxicologically relevant PAHs not clarified yet. In this work, the impact two commercially available oxidizing platinum/palladium with either metallic or ceramic...
The crucial point in inorganic particle formation from biomass combustion is the temperature-dependent release of compounds, especially potassium (K). Currently, common wood fuels comprise a comparatively low amount K, but increased usage energy requires new feedstocks future. Potentially feedstocks, such as short rotation coppice (SRC), agriculture (e.g., straw), or broad-leafed trees rotation, contain usually high ash contents and/or K concentrations. Apparently, these will cause emissions...
In Europe, the official-type test method (oTT) according to standard European Norm (EN) 13240 evaluates emissions and thermal efficiency of firewood roomheaters only under optimal conditions, that is, heated up at nominal load. this study a novel method, called “beReal”, is presented which was developed reflect real-life operation within testing procedure. The beReal concept consists heating cycle with eight consecutive batches covers all typical phases operation. A specific procedure based...
