描述了一种评估燃气或燃油炉季节效率的方法，该燃气或燃油炉位于室内加热空间，并使用调节空气进行燃烧和通风控制。它包括以下四项任务:1）在稳态运行期间测量fluegas温度和CO2浓度；2） 从稳态条件下冷却和升温时，获取关于烟气温度与时间曲线形状的信息；3） 将适当的值分配给各种因素，这些因素描述了通过烟道和烟囱的关闭期空气流量、炉膛过大的程度以及炉膛运行对渗透的影响，4）执行本文所述的计算程序，以确定各种开启时间- 周期和非周期损失以及在任何给定气候区域运行的熔炉或锅炉的季节效率。我们举出了几个例子来说明这个简化过程的本质。引文:研讨会论文，佐治亚州亚特兰大，1978年

An evaluation procedure is described for estimating the seasonal efficiency of a gas or oil-firedfurnace which is located in an indoor heated space and uses conditioned air for combustionand draft control. It involves carrying out the following four tasks: 1) measuring the fluegas temperature and C02concentration during steady-state operation; 2) obtaining informationon the shape of the flue gas temperature-vs-time curves as a unit cools down and warms up fromsteady-state conditions; 3) assigning appropriate values to various factors which describe theoff-period air flow rate through the flue and stack, the degree of furnace oversizing, and theeffect of furnace operation on infiltration, and 4) carrying out the calculation proceduredescribed herein to determine the various on-period and off-period losses and the seasonalefficiency of a furnace or boiler operating in any given climatic region. Several examplesare worked out to illustrate the nature of this simplified procedure.
