When using solid fuels for live fire training, NFPA 1403: Standard on Live Fire Training Evolutions requires that the materials be wood based. While the standard offers guidance on the type of fuels that are permissible for use in training, it offers little in the way of quantitative methods of selecting an appropriately sized fuel package. In order to examine the effects of fuel mass and orientation on heat release behavior, free burn heat release rate (HRR) experiments were conducted on twenty-one wood-based training fuel packages and twelve comparison furniture items. Training fuel packages demonstrated peak HRRs ranging from 1.0 MW to 3.6 MW, with the total energy release between 210 MJ and 1615 MJ. The furniture items exhibited peak HRRs between 0.9 MW and 3.7 MW, with the total energy release between 180 MJ and 995 MJ. A least-squares linear regression analysis indicated a good linear fit between total energy release and fuel mass burned among the training fuel packages (R\(^2\) \(=\) 0.98), suggesting that the effective heat of combustion is approximately constant at 14.2 MJ/kg. Generally, peak HRR increased as initial fuel mass increased, although the relationship was more variable, with the peak HRRs of similarly sized training fuel packages varying by nearly 1 MW. The results indicated that while total energy release was dependent largely on the initial fuel mass, peak HRR and peak burning duration were also dependent on the orientation and type of fuel in the fuel package. Wood-based training fuel packages were capable of producing peak HRRs comparable to individual items of furniture, although the total energy release was typically higher for the training fuel packages compared to corresponding furniture items.

当使用固体燃料进行实火训练时，NFPA 1403：实火训练演变标准要求材料是木质的。尽管该标准提供了允许在培训中使用的燃料类型的指南，但它几乎没有提供定量方法来选择适当大小的燃料包。为了检查燃料质量和取向对放热行为的影响，对21个木质训练燃料包和12个比较家具项目进行了自由燃烧放热率（HRR）实验。训练燃料包的峰值HRR在1.0 MW至3.6 MW之间，总能量释放在210 MJ至1615 MJ之间。家具物品的峰值HRR在0.9 MW至3.7 MW之间，总能量释放在180 MJ至995 MJ之间。\（^ 2 \） \（= \）  0.98），表明有效燃烧热大约恒定为14.2 MJ / kg。通常，峰值HRR随初始燃料质量的增加而增加，尽管这种关系变化更大，而类似尺寸的训练用燃料组件的峰值HRR则相差近1 MW。结果表明，虽然总的能量释放主要取决于初始燃料质量，但峰值HRR和峰值燃烧持续时间也取决于燃料组件中燃料的方向和类型。木质培训用燃料包装能够产生与单个家具相比的峰值HRR，尽管与相应家具相比，培训用燃料包装的总能量释放通常更高。
