摘要
基于载体催化元件检测甲烷浓度的基本原理,提出了采用载体催化元件和参比元件组成惠斯登测量电桥,运用温度自动控制系统达到恒定甲烷无焰燃烧温度,实现甲烷浓度的测量。扩展了采用载体催化元件测量甲烷浓度时的测量范围,减轻了催化剂的高温烧结和挥发现象,延长了载体催化元件的使用寿命。并建立了相应的温度自动控制和甲烷浓度测量的数学模型。
Based on the basic principle of sensors with supporter filled element that measures the methane concentration, a method for designing Weston bridge by using the sensor and the reference element is proposed and the mathematical model of the automatic temperature control and the measurement of methane concentration is developed. The measurement results show that this design expands the measuring range, reduces burning-knot and vaporization of catalyst and extends the service life of the supporter catalyst filled element.
