根据煤表面分子结构的类型，推出煤体表面分子存在的7种活性结构，这些活性结构是低温下与氧发生化学反应的主体煤表面活性结构与氧复合过程存在化学吸附和三步化学反应过程，根据每步反应化学键能的变化，可推算出化学吸附及反应每生成1molCO，CO2等气体产物的平均键能变化量通过实验可测定煤体在不同温度下的耗氧速率，CO及CO2产生速率，若煤氧复合消耗的氧全部转化成CO和CO2，二者的产生量与各自的实际生成量成正比，则据耗氧速率、CO和CO2产生速率，可算出煤氧复合放热强度；若煤氧复合消耗的氧除实际生成CO和CO2外，其余均与煤发生化学吸附，据此同样可计算出煤氧复合放热强度由于煤氧复合实际消耗的氧，一部分与煤发生化学吸附，一部分与煤反应生成中间产物，还有部分与煤反应生成CO和CO2，故煤氧复合实际放热强度介于两者的计算结果之间
According to the types of molecular structure of coal surface, seven kinds of active structures exist on the surface of coal. These active structures are the main part of the chemical reaction with oxygen at low temperature. There are chemical adsorption and three-step chemical reactions in the coal surface active structure and oxygen recombination process According to the change of the chemical bond energy per reaction step, the average bond energy change per 1 mol CO, CO2 and other gas products can be calculated by chemical adsorption and reaction. The oxygen consumption rate, CO and CO2 production rate, if the oxygen consumption of oxygen and oxygen are all converted into CO and CO2, both the amount of production and their actual production is proportional to, according to oxygen consumption rate, CO and CO2 production rate can be calculated If the oxygen consumed by the complex oxygen and oxygen in addition to the actual generation of CO and CO2, the rest are chemically bonded with the coal, which can be calculated according to the same oxygen exothermic strength of coal due to the actual consumption of oxygen complex oxygen, part of the Coal chemical adsorption, part of the reaction with the coal to generate intermediate products, and some react with coal to generate CO and CO2, so the actual oxygen and oxygen recombination intensity between between the results of those
