This research work focuses on the study of the issue of the effective use of natural gas and fuel oil for the ignition of pulverized coal torches of boilers at thermal power plants. The main goal of this work is to conduct an analysis of experimental studies and identify the optimal flow rate of natural gas and fuel oil, which ensure the most effective and economical ignition of a pulverized coal torch.

Тhe results of a numerical study of heat transfer in water-tube boiler DKVR(DE)-10/14 furnace are provided. The geometric model of the inner cavity of furnaces and burners is constructed with help of boiler and burner GMG-7 drawings. The mathematical model of radiate and convective heat transfer with gravity in the gas path of the boiler on the basis of the Reynolds averaged incompressible Navier – Stokes equations is formed. The model incorporate continuity, momentum, energy and chemical components transfer equations of the gas mixture stored in a stationary manner.

The mixing and burning of natural gas with heated air in the reactor of carbon black obtaining have been analyzed. Commercial test results for the device of partially premixed components with single-flow burner have been considered. Construction peculiarities and operational conditions of single- and multi-flow burners have been examined.
