Adamenko D. The increase of boiler units work effectiveness by pulsation-acoustic incineration of fuel

The dissertation is devoted to the increase of natural gas incineration effective-ness in industrial boiler units on the basis of the designed system and technology of pul-sation-acoustic incineration of fuel. The system of differential equations for heat exchange, motion and continuity of a gas stream in a turbulent diffusion torch, which is formed under exterior pulsation-acoustic action, is proposed for the first time. This system is based on the quantity of the linear size of vortexes. The frequency band of an amplitude-frequency characteristic of a torch depend-ing on the constructive performances of the burner is determined. The influence of the linear size of vortexes on intensification of processes formations of intermixture and incineration of gaseous fuel in the turbulent diffusion torch, which is formed under exterior pulsation-acoustic action, is determined. The mathematical model of thermal and gasdynamic processes occurring in a steam boiler furnace during pulsation-acoustic incinerationof fuel is elaborated and adapted. The intensification of the external pulsation-acoustic actions influence on the quality of incineration gaseous fuel in a steam boiler furnace has been experimentally confirmed for the first time. The method and design of the system of pulsation-acoustic incineration of fuel in boiler units furnaces as well as the boiler furnace for realization of the method have been developed and industrially probed. The technological recommendations for applying the system of pulsation-acoustic incineration of fuel in different boiler units types have been developed.
