Beztsennyj I. The main regularities of the pulverized co-combustion processes of varying metamorphism degrees coal

The work is devoted to the study of the peculiarities of various metamorphism degrees coal blends pulverized combustion. The anthracite, lean and bituminous coal chars and their blends were investigated for determination the kinetic characteristics of combustion. The different metamorphism degrees coal blends combustion dynamics method of engineering calculation in a non-isothermal flow has been developed. The reference data of the Normative method of boiler calculations for the coal blends pulverized combustion case is supplemented. A substantiation of the fuel regime organization for anthracite and bituminous coal blends pulverized combustion (the content of bituminous coal up to 30%) is presented. This blend combustion results on boilers TP-100 and TPP-210 of the Zmiyiv TPP have shown improvement of technical and economic indicators compared with combustion of anthracite.
