“…A sample is dried at 105 ± 2 °C until its mass remains constant. Due to the standardisation and, thus reproducibility, this method is often used as a reference method for investigations of the accuracy of other or new analysis methods [44][45][46][47][48][49][50][51][52]. Besides the standardised method at 105 °C, the drying process can also be carried out at lower (e.g., 80 °C) or higher (e.g., 130 °C) temperatures.…”

Fuel properties of solid biofuels are essential aspects for the energy‐efficient and low‐emission operation of biomass heat and power plants. Hence, fuel quality parameters are often defined and used for pricing in supply contracts. To simplify and accelerate analytical approaches, rapid analysis devices are required to determine fuel properties such as water‐ and ash content, calorific value, and chemical composition on‐site. This article gives an overview about available technologies and, if applicable, their current state of use as rapid analysis devices for solid biofuels.

“…In contrast, the ZS (the ZS chimney has a 90°angle at its joints) chimney maintains a higher overall internal stove temperature. Endriss et al 16 showed that the draft influences temperature, while the particulate matter concentrations significantly decreased with the increase in draft. Mehta and Richards 17 experimentally studied a top-lit updraft cook stove and reported that the char remaining at the end of gasification decreased with the increased diameter of the combustion chamber.…”

Although the Chinese government encourages using clean fuels for heating, many households in remote areas still rely on coal as their energy, especially in the Qinghai Tibet Plateau. An updraft coal heating stove was modified to preheat secondary air. The performance of the modified stove was studied compared with a baseline stove. The temperatures in the combustion chamber and near the chimney exit are measured, and the undiluted exhaust concentrations of CO, NO x , and SO2 are obtained. The results indicated that the temperatures and exhaust gas concentrations varied periodically with the coal addition. The oxygen concentration in the flue gas for the modified stove is higher than that for the baseline stove, and the O2 concentration was decreased with the increase in fuel feed rate. The CO concentration peaked 5–15 min after fuel addition and descended quickly toward a baseline with the higher fuel feed rates. It remained almost unchanged at the beginning and then slightly increased when the combustion began to fade with a lower fuel feed rate for the modified stove. The NO x emission for the modified stove is generally lower than that for the baseline stove. The NO x formation during coal combustion mainly comes from prompt NO and fuel NO, while the SO2 emission is mainly related to the sulfur element in the raw coal in the present work. The modified stove is effective in reducing NO x and SO2 emissions. However, the CO emission of the modified stove is higher than that of the baseline stove, especially at the end of the batch.

Die Studie zeigt den Einfluss der Zersetzungsprozesse bei Buchen‐ und Kiefernholz auf die Brennstoffqualität und Verbrennungschemie in einem Scheitholzofen. Insbesondere bei einer volumenbezogenen Betrachtung der aufgegebenen Holzmenge nehmen die Abbrandzeit und die Energieabgabe mit dem Zersetzungsgrad ab. Die gasförmigen Emissionen sowie die Staubemissionen ändern sich, in Abhängigkeit der Zersetzungsprozesse, nicht. Bei den hier durchgeführten Versuchen zeigten sich bei der Verbrennung von Nadelholz generell geringere gasförmige Emissionen als bei Laubholz.
