煤焦非均相着火温度与煤种的通用关系及判别指标

A General Correlation Between Non-Homogeneous Phase Ignition Temperature of Coke and Coal Category And Discrimination Indexes,Power Engineering

本文找到了煤焦非均相着火温度与煤种的通用关系式,对几十种煤进行了检验,结果较满意.这样,使煤焦着火温度的预报既简单又可靠,适合工程计算应用.本文还给出了表征煤焦着火特性优劣的着火特性通用指标Fz数;提供了一个判别煤焦着火的准则;还给出了一个按煤焦着火特性难易程度排列的表,它对工程设计人员和运行人员有指导意义.

A general correlation between non-homogeneous phase ignition temperature of coke with coal category is found, with which dozens of coal species have been satisfactory discriminated. Being not only simple but also reliable, this method of prediction is well suited for engineering application. In addition to an index Fz, which indicates coke ignition characteristics, the paper proposes a criterion for distinguishing coke ignition together with a list of coke categories arranged according to their ease of ignition which may be helpful for engineering people and operators.
