Potentials and Prospects of Numerical Investigation of the Thermal Efficiency Optimization in Radiant Tube Burners

Abstract

The paper is designed to present optimization of the radiant tube burners efficiency vital to maximize the heat transfer and minimize the energy input while operating at acceptable pollutant emission levels. The aim is to help demonstrate its value to the country’s citizens in providing visible and tangible results by presenting strategy on how to combat the impact of rising fuel prices and the need to comply stringent pollutant emission standards. A numerical study of the combustion and heat transfer process in single-end radiant (SER) tubular burners is presented. Finally the potential benefits of the discrete transfer radiation by method (DTRM) with the weighted sum grey gas (WSGG) model (none grey model) is applied in the simulations of combustion inside a radiation tube burner to calculate the thermal radiation
