摘 要：以煤燃燒過(guò)程分析研究為基礎(chǔ)，將煤燃燒過(guò)程分解為煤干燥過(guò)程、煤熱解過(guò)程、燃燒過(guò)程和氣渣分離過(guò)程，詳細(xì)分析各過(guò)程的機(jī)理并建立相應(yīng)數(shù)學(xué)模型，重點(diǎn)開(kāi)展對(duì)常規(guī)分離器模型的優(yōu)化。將該煤燃燒過(guò)程模型應(yīng)用于Texaco氣化爐，通過(guò)對(duì)該過(guò)程進(jìn)行編程求解，計(jì)算所得的模擬值與文獻(xiàn)值吻合較好，證明所建立的煤燃燒過(guò)程模型準(zhǔn)確合理，為煤燃燒過(guò)程的工藝流程的數(shù)值模擬研究奠定了基礎(chǔ)，可用于氣體組成、除塵、脫硫等不同工藝過(guò)程的數(shù)值模擬研究。在此模型的基礎(chǔ)上，進(jìn)一步分析了在一定物流參數(shù)下不同溫度對(duì)Texaco氣化爐煤燃燒生成合成氣組成的影響。

Abstract：Based on the analysis of coal combustion process，the coal combustion process is separated into coal drying process，coal pyrogenation process，combustion process and slag separation process in this study. Each process is analyzed in detail and the corresponding mathematical model is established. The optimization of conventional separator model is focused. The model of coal combustion process is applied to Texaco gasifier. The simulated data is consistent with that the literature reported，which proves that the model of coal burning process established is reasonable. It is basic to the numerical simulation study of coal combustion process and can be applied in the numeri....
