【摘要】：本文基于PSR(Perfectly StirredReactor)开发了一种适用于模拟气体燃料MILD(Moderate and Intense Low-oxygen Diluttion)燃烧的化学反应动力学网络模型。该模型使用多个PSR串联,模拟了燃炉内天然气MILD燃烧的预热、烟气卷吸和燃烧过程。本文同时考虑了炉体散热和烟气卷吸量等因素,建立适用于气体燃料MILD燃烧的PSRN模型。研究表明,所建立的PSRN模型能够有效模拟气体MILD燃烧的温度、二氧化碳浓度等结果。此外,该模型能够准确模拟出N_2和CO_2稀释下燃气的MILD燃烧过程,说明了该PSRN模型具有普适性。
[Abstract]:Based on PSR(Perfectly Stirred Reactor, a chemical reaction kinetic network model for simulating the combustion of gas fuel MILD(Moderate and Intense Low-oxygen reactor is developed in this paper. The model uses several PSR series to simulate the preheating of natural gas MILD combustion in the furnace. In this paper, a PSRN model suitable for MILD combustion of gaseous fuel is established by taking into account the factors of furnace body heat dissipation and flue gas entrainment. The results show that the established PSRN model can effectively simulate the temperature of gas MILD combustion. In addition, the model can accurately simulate the MILD combustion process of the gas under N _ 2 and CO_2 dilution, which shows that the PSRN model is universal.
