Abstract
In article we propose mathematical models for stationary and dynamic processes of technological furnaces as object with distributed parameters. This mathematical model is based on the laws of conservation of energy, mass and impulse and includes differential equations in private derivatives. Computational investigation of stationary modes of tubular furnaces is conducted. Formulated boundary-value problem for calculation concentration of combustible substance, density, speed, temperature of the flue gas and temperature of the heated raw materials going on division in rectificative column. Results of calculation technological parameters are presented. The proposed method can be used at automation rectificative plant in petroleum-refining and petrochemical industry.
