掺氨混合燃烧实验台搭建及应用研究

Research on the construction and application of ammonia mixed combustion test bench

摘要

氨（NH₃）作为一种零碳燃料，在能源转型中具有重要潜力，但其燃烧特性复杂，存在点火困难、火焰传播速度慢及氮氧化物（NOx）排放高等问题。本文设计并搭建了一套小型化掺氨混合燃烧实验台，通过模块化设计、国产设备替代及智能数据采集系统集成，实现了氨与氢气、甲醇等燃料的混合燃烧特性研究。现有掺氨燃烧实验室投入大占地广，每次实验成本高，不利于日常实验和教学，实验台总成本控制在10万元，具备10Hz级实时数据采集能力，NOx检测精度达±5%，火焰温度测量范围覆盖400~1800℃。

Abstract

Ammonia (NH₃) has important potential as a zero-carbon fuel in the energy transition, but its combustion characteristics are complex, and there are problems such as difficult ignition, slow flame propagation, and high nitrogen oxide (NOx) emissions. In this paper, a set of miniaturized ammonia-doped mixed combustion test benches was designed and built, and the mixed combustion characteristics of ammonia, hydrogen, methanol and other fuels were studied through modular design, domestic equipment substitution and intelligent data acquisition system integration. The total cost of the laboratory bench is controlled at 100,000 yuan, with 10Hz real-time data collection capabilities, NOx detection accuracy of ±5%, and the flame temperature measurement range covers 400~1800 °C.
