在原有理论燃烧温度（TCT）计算模型的基础上进行了修正。对喷煤粉（PCI）的燃烧比、PCI的分解热、高温环境下还原灰中SiO2的热耗等因素进行了修正和改进，提出了更全面的TCT计算模型。研究了每次改进对炉膛热态的影响，并将改进后的模型与传统模型和原模型进行了对比分析，结果表明，改进后的模型能更有效地反映炉膛热态。
On the basis of the existing originally modified calculation models of theoretical Combustion temperature (TCT). some factors, such as the combustion ratio of pulverized coal injection (PCI), the decomposition heat of PCI and the heat consumption of SiO2 in ash reduced in high temperature environment, were amended and improved to put forward a more comprehensive model for calculating TCT. The influences of each improvement on TCT were studied and the results were analyzed compared with those of traditional model and originally modified model, which showed that the present model could reflect the thermal state of a hearth more effectively.
