Горение и окисление аммиака с добавками углеводородов и оксигенатов

Abstract

Ammonia and its mixtures with hydrocarbons and oxygenates are promising low-carbon fuels. In this work, the oxidation of ammonia mixtures with methane, ethane, ethylene, acetylene, as well as with methanol, ethanol, butanol, methyl and diethyl ethers in an isothermal jet-mixing reactor at atmospheric pressure, a temperature of 600-1300 K, and equivalence ratios of φ=0.5-2.0 was studied experimentally and numerically. The thermal and chemical structure of flames of mixtures of ammonia with methane, ethane, ethylene, and acetylene stabilized on a flat burner at pressures of 1, 3, and 5 atm in the range of equivalence ratios of φ=0.8-1.2 was studied using molecular beam mass spectrometry, microthermocouples, and numerical simulation.
