Description
Summary:Within the framework of the differential method of thermal calculation of furnaces, the thermal regime in the radiation chamber of a tubular furnace for pyrolysis of the propane-butane fraction was determined using propane as a raw material. The fuel used was natural gas, mainly methane. The interrelated processes of combustion of fuel gas, heat and mass transfer in the combustion chamber are analyzed by numerically solving finite-difference analogs of the integro-differential equation for energy transfer by radiation and differential equations in partial derivatives of conservation of energy, momentum, combustion and turbulence models. As a result of the calculations, the fields of temperature and velocity of combustion products in the radiation chamber, the temperature of the inner surface of the lining, and heat fluxes to the tubular screen were established. Specific consumption of equivalent fuel per ton of propane and heat losses have been determined. Optimal operating modes of the furnace have been established, recommendations have been made for reliable and economical operation of the furnace.
