However, K+ emission seems to be higher in flaming-dominated combustion at higher temperature.
The absence of such an enrichment can be explained on the one hand by the significantly lower combustion temperature in the miscanthus combustion plant and, on the other hand, by the higher molar ratio of K to Cl and the low ratio of K to Si.
Daily changes in air temperature, relative humidity, and light intensity that cause species-specific physiological changes may account for the variation in weed control throughout the day.
The calculated combustion zone temperature and temperature profiles are in good agreement with our experimental data.
The detailed in-combustor data show that the temperature and the O2 mole fraction fields are relatively uniform, and that the maximum mean temperatures reached throughout the combustion chamber are relatively moderate, below 1500 °C, even under conditions in which the level of preheating of the combustion air is relatively high.
The lack of definitive relationships between temperature and weed seed viability demonstrated that factors other than temperature may play a role in eliminating weed seeds during composting.
Flaming for weed control has been receiving attention of several corn producers in North Central USA and Europe, and it can be an important tool in an integrated weed management program.
A narrow temperature tolerance is a potential limiting factor for the establishment of weed biological control insects in novel habitats.
This is due to the fact that at this ratio, the combustion products have their highest temperature.
They also suggest an influence of radiant energy on weed emergence.
Flaming can be an effective nonselective, nonchemical method of weed control.
Overall, the model shows good agreement with experimental data regarding both, low and high temperature combustion characteristics.
Thus, evaluating flame weeders based on temperature measurements alone without knowledge of the relationship between temperature and weed control is not recommended.
Flame weeding is an acceptable weed control option in both organic and conventional production systems.
The results of this study indicate the significant effect of temperature on postdispersal weed seed predation.
The main result is that, for the weed species examined in this study, the use of alternating temperatures for base temperature estimation appears to be possible.
Measured temperature profiles indicate that effect of volatile combustion on inner temperature profile was ignorable.
These results suggest that similar model structures could be used to quantify temperature effects on seed dormancy status of other weed species and to develop predictive models of weed emergence.
The results, reported at two different physical times, show the effects of the different combustion models, which predict different temperature and species concentration maps, but similar values for the combustion efficiency.
The results thus clearly show a strong correlation between the preignition temperature field and the subsequent combustion process.

What is the temperature required for combustion of coconut husk?5 answersThe temperature required for the combustion of coconut husk varies depending on the specific study. Research by Jerzak and Kuźniaindicates that combustion temperatures ranging from 600-1000°C affect the concentrations of chlorine species in the flue gas, with different species dominating at different temperature ranges. On the other hand, studies by Yulianto et al.and Oladosu et al.focus on the combustion of coconut shells and a blend of coconut husk with Palm Kernel Shell (PKS), respectively. While Yulianto et al. do not provide a specific combustion temperature, Oladosu et al. mention conducting combustion tests with a stable bed temperature of 248.7°C and recording temperatures above the grate reaching up to 720.9°C for specific fuel proportions. Therefore, the combustion temperature for coconut husk can range from around 250°C to over 700°C, depending on the study and specific conditions.

What is the effect of temperature on pyrolysis?3 answersPyrolysis temperature has a significant effect on the properties and yields of pyrolysis products. Increasing the pyrolysis temperature generally leads to changes in the chemical and structural properties of the materials being pyrolyzed. For example, in the case of agricultural wastes, pyrolysis at higher temperatures resulted in a decrease in organic carbon content and an increase in pH. Similarly, in the pyrolysis of high-density polyethylene (HDPE), the yield and quality of carbon nanofilaments (CNFs) and hydrogen-rich gas were found to be optimal at a temperature of 650 °C. The temperature also affects the condensation efficiency, moisture content, and important component content of bio-oil produced from pyrolysis of cotton straw and corn straw. Higher pyrolysis temperatures led to increased condensing efficiency and content of important components in the bio-oil. Temperature oscillation during torrefaction of biomass also influenced the subsequent pyrolysis reaction, affecting the weight loss rates and activation energy of the material. In the pyrolysis of pine sawdust, increasing the temperature resulted in higher yields of bio-gas with higher heating values, while the yield of bio-char decreased.
Is peak temperature important in combustion studies?5 answersPeak temperature is an important factor in combustion studies. The combustion characteristics, such as ignition and burnout, can be influenced by the peak temperature. For example, in the study by Wang et al., it was found that the point of ignition and burnout shifted to lower temperature with increasing proportion of rice straw in the mixture. Additionally, Golodova and Shchepakina used canard techniques to estimate the maximal temperature of safe combustion in multi-phase combustion models. Furthermore, Lendvay and Laszlo observed changes in smoke composition with temperature, indicating the dependence of cigarette smoke composition on temperature. Moreover, Milligan et al. found that particle size had a significant effect on combustion profiles, with increased complexity in terms of the number of peaks observed for micronized coal compared with larger size fractions. Therefore, peak temperature plays a crucial role in understanding and predicting combustion behavior.
