“…In Table 2 , there are no significant differences between the ignition times of the three straws (about 7–10 s). The HRR curves of crop straws are shown in Figure 2 a. HRR is a very important parameter for evaluating the burning behaviors of biomass materials [ 21 ]. The shapes of the HRR curves of the three crop straws are similar.…”

Crop residue burning is one of the major sources of particulate matter (PM) in the air. The burning behaviors and PM emissions of the three typical crop residues (rice straw, wheat straw, corn straw) in China were characterized by a cone calorimeter (CONE) coupled with a laser dust meter. The water-soluble compounds, carbonaceous content, and morphology of PM were measured by ion chromatography, elemental analyzer, transmission electron microscopy (TEM) and energy-dispersive X-ray spectrometer (EDS). The results showed that thermal stability of corn straw was the worst among the three crop straws. The heat release rate (HRR) curves of the three crop straws were the typical curves of thermally thick charring (residue forming) samples. Wheat straw had the highest smoke yield, which was 2.9 times that of rice straw. The PM emission factor of wheat straw was 180.91 µg/g, which was about three times that of rice straw. The contents of K+, Na+, and Cl− in PM were significantly higher than those of the other six water-soluble inorganic ions. The ratio of organic carbon and elemental carbon (OC/EC) ranged from 14.82 to 30.82, which was similar to the results of open burning. There were mainly three kinds of aggregates in the PM of crop straws: network, chain-like, and soot. Individual particles were mixtures of KCl and organic matters. Core-shell structures were found in PM of rice straw and corn straw. The results in this study were provided based on CONE, an ISO-standard apparatus, which could avoid data conflicts caused by the difference of combustion devices. The relationship between the burning behavior and PM emission characteristics of crop straws was established, which is helpful to understand emissions of crop straws and to find a novel way to solve the problems from the burning of crop residues.

“…The HRR value in the discharge of the fire retardant-treated wood specimens did not exceed the limit of the standard. The HRR is the main indicator for the risk of flame spread (Grexa and Lubke 2001;Lee et al 2011;Dao et al 2013;Seo et al 2016b). It is also used to evaluate the flame spread on the surface of materials.…”

The combustion and thermal characteristics of fire retardant-treated pine (Pinus densiflora) were evaluated according to the KS F ISO 5660-1 (2003) standard, using a cone calorimeter. The specimens were treated with fire-retardant chemical compounds using pressure-impregnation equipment to reliably impregnate the compounds inside the wood. The heat release rate value of the fire retardant-treated wood specimens showed that the heat release time was delayed. A reduction of the total heat release value can indicate that fire was prevented from igniting in the materials during combustion. The microstructures of natural specimen and treated fire-retardant chemical compounds specimen were determined by scanning electron microscopy. It also confirmed that the pressureimpregnation processing method was effective in comparison to the other treatment methods.

“…A cone calorimeter (Fire Testing Technology, East Grinstead, UK) and FT-IR (Midac Co., MA, USA) were used for the analysis of calorific value and combustion gas. The cone calorimeter is widely used to measure the calorific value of samples (Seo et al 2016;Liang et al 2017), and FT-IR is mainly used to look at the chemical bonding of solids (Cal et al 2016;Li et al 2017), but in this study, it was used for a combustion gas analysis. Calorific value measurement was conducted in accordance with ISO 5660-1 (2015), and the combustion gas analysis was conducted in accordance with the test method specified in ISO 19702 (2015).…”

As biomass has become increasingly important, wood pellets are becoming more widely used, and the storage of wood flour, which is the raw material of wood pellets, has become inevitable. The purpose of this study was to reduce the economic losses from fires during storage of porous combustible materials. To achieve this purpose, the authors analyzed and compared the wood flour loss rate between the use of water and the use of wetting agents to extinguish a deep-seated fire through a scale model experiment. To do this, the authors measured the penetration amount of the water and dilute solutions of wetting agent, the weight change of the wood flour holder, and the emissions on a real time basis when that spray amount was the same. Furthermore, the authors analyzed the calorific value and combustion gas to examine the reusability of the wood flour with the added wetting agent. This study quantitatively demonstrated that the active use of wetting agents in wood flour storage fires dramatically reduced the fire loss rate of raw materials and resulted in early fire extinguishing, which minimizes companies' economic loss.
