【 摘 要 】

In this paper pulverized combustion of insufficiently investigated low-grade Pavlovskiy coal is simulated using the modern engineering software FIRE 3D. The object of study is a widespread in Russia BKZ-210-140 steam boiler. The results of computer simulation are represented with average temperatures in horizontal sections and oxygen concentration. Curves are plotted for three steam generating capacity loads of the boiler: 100%, 70% and 50%.
