Abstract :
Present work describes the influence of thermal boundary layer on the distribution of heat transfer across a cylinder (crucible) particularly examined. The experimental investigations performed in the specially designed medium size crucible furnace, and the data has recorded in a conventional (steady state) as well as oscillating combustion technology mode. The comparisons have been taking place to verify the significance of oscillations at different frequencies, and amplitudes which are influence the breakup of thermal boundary layer formation during the conventional combustion mode. The thermal boundary layer obstructs the heat transfer from the flame to load (cylinder) due to its thickness. The heat losses can minimise by applying oscillating combustion due to its luminous and fuel rich and fuel lean zones this technology needs an oscillating valve it was designed and developed by author and incorporated in the fuel line and ahead of the burner to create oscillations in a flame. And it has been operated at different frequencies 3 Hz, 5 Hz and 7 Hz also amplitudes 300, 600 and 900.
