木（或煤）炉（或火炉）的一些重要性能特征是:1）其热输出率的有效范围（例如，以Btu/小时或瓦特为单位），2）在各种情况下的能源效率，3）不同平均热输出率下燃料加载之间的最长时间，4）燃料加载之间的热输出率的稳定性，5）在八到十个小时后保留足够热煤的能力，以便很少需要重新点火；6）杂酚油形成的倾向；7）燃料装载的便利性、除灰的便利性和频率；8）安全性；以及9）耐久性。这种可靠的信息很少。部分原因与两个实验问题有关。1） 木材加热器的性能受到除炉子设计以外的许多因素的强烈影响- -诸如木材类型、水分含量、尺寸、炉子是否在燃料限制或氧气限制燃烧模式下运行、烟囱质量等因素。这些因素使任何测试工作复杂化——要么需要进行大量测试，以充分描述加热器在所有条件下的特性，要么必须任意限制测试条件，希望但不确定，所选条件要么代表所有条件（这不太可能），要么至少是典型或平均条件。2） 如何测量木材加热器的性能存在一些不确定性——需要测量哪些参数以及如何测量这些参数。如今，评估热量输出和效率的唯一现成技术是传统的烟囱损失法，而这种方法几乎肯定不适用于木炉。 本文的目的是对测试技术，尤其是测量上述前四种炉具特性所需的测试技术进行批判性概述，详细描述我们自己的测试方法和程序，并给出一些初步实验结果。引文:研讨会论文，佐治亚州亚特兰大，1978年

Some important performance characteristics of a wood (or coal) stove (or furnace) are 1) its useful range of heat output rates (e.g., in Btu per hour or watts), 2) its energy efficiency under various circumstances, 3) the maximum time between fuel loadings at various average heat output rates, 4) the steadiness of the heat output rate between fuel loadings, 5) the ability to retain sufficient hot coals after an eight-to-ten-hour period so that rekindling the fire is seldom required, 6) the proclivity towards creosote formation, 7) the ease of fuel loading and ease and frequency of ash removal, 8) safety, and 9) durability.Little reliable information of this sort is available. Part of the reason is related to two experimental issues. 1) The performance of wood heaters is strongly influenced by many factors other than stove design -- factors such as the type of wood, its moisture content, its size, whether the stove is operated in a fuel-limited or oxygen-limited combustion mode, chimney quality, etc. These factors complicate any testing effort -- either very many tests are needed to fully characterize the heater under all conditions, or test conditions must arbitrarily be limited, hoping, but not being sure, that the chosen conditions are either representative of all conditions (which is unlikely) or at least that they are typical or average. 2) There is some uncertainty about how to measure wood heater performance -- what parameters to measure and how to measure them. The only readily available technique today for assessing heat output and efficiency is the traditional stack-loss method, and this method is almost surely inadequate when applied to wood stoves.It is the intent of this paper to present a critical overview of testing techniques, particularly those needed for measuring the first four stove characteristics listed above, to describe our own testing methods and procedures in some detail, and to present some preliminary experimental results.
