A study was undertaken to identify patterns of consumer use of outdoor wood boilers or outdoor wood furnaces (technically referred to as outdoor wood-fired hydronic heaters (OWHHs)) and indoor wood stoves (IWSs) to inform the development of performance testing protocols that reflect real-life operating conditions. These devices are manually fed, and their usage pro are a function of a number of variables, including user habits, household characteristics, and environmental factors. In this study, researchers logged the stack wall temperatures of 4 OWHH and 20 IWS units in the states of New York and Washington over two heating seasons. Stack wall temperature is an indicator of changes in combustion modes. Two algorithms were developed to identify usage modes and cold and warm start refueling events from the stack wall temperature time series. A linear correlation analysis was conducted to evaluate the effect of heat demand on usage patterns. The results and methods presented here will inform the cataloging of typical operational patterns of OWHHs and IWSs as a step in the development of performance testing procedures that represent actual in-home usage patterns.

使用烟囱温度数据研究木材燃烧器的实际运行模式。

进行了一项研究，以确定消费者使用室外木材锅炉或室外木材炉（技术上称为室外木材燃水循环加热器（OWHH））和室内木材炉灶（IWS）的方式，以告知性能测试协议的制定实际操作条件。这些设备是手动送入的，其使用情况是许多变量的函数，包括用户习惯，家庭特征和环境因素。在这项研究中，研究人员在两个供暖季节记录了纽约州和华盛顿州4个OWHH和20个IWS装置的烟囱壁温度。烟囱壁温是燃烧模式变化的指标。开发了两种算法来从烟囱壁温度时间序列中识别使用模式以及冷，热启动加油事件。进行了线性相关分析，以评估热需求对使用模式的影响。此处介绍的结果和方法将有助于对OWHH和IWS的典型操作模式进行分类，这是开发代表实际家庭使用模式的性能测试程序的一个步骤。
