About the Рroblems of Design of Furnaces-Satellites for Environmentally Safe Burning of Old Railway Sleepers

Abstract

Presents the results of experimental and theoretical studies of burning old sleepers in the combustion chamber of the combined type. Theoretical studies were carried out using the program ANSYS FLUENT. The experiments were conducted on a specially designed stand. The experiments measured the temperature of the combustion products; complete gas composition at the outlet of the flue pipe; flow rate and the temperature of the air supplied to the furnace. The experiments showed that in addition to the products of pyrolysis and oxidation of wood (СН₂О, CH₃OH, etc.) in flue gases are highly toxic and the oxidation products of aromatic hydrocarbons. Intensification unterkuernach processes by combining the scheme for supplying air jets in the combustion chamber not solve the problem. The decision of the authors of a joint burning old sleepers in the furnaces of satellites connected to industrial power boilers with discharge of combustible gases in the furnace of this boiler is technically correct.
