Thermally Induced Stress Cycling (Thermal Shock) i

Description of Construction and Inspection Procedure for Steam Locomotive and Fire Tube Boilers : (Thermal Shock) Recommendations as to how to set burner controls to maximize the boiler shell temperature for a given operating pressure, and minimize the number of operating cycles and the burner firing rate, for a given load condition.

FURNACES - thermopedia.c

The rate of heat transfer,, from the hot gases to the tubes is a function of the gas temperature as well as the radiation properties of the gases, the geometry of the furnace and tubes, and the emissivity of the tube surface. In applying simple furnace models iteration is therefore necessary.

Estimation of furnace exit gas temperature (FEGT

Furnace tubes viewed by the flame are treated as radiant heat transfer surfaces whereas other boiler tubes downstream of furnace are assumed convective or a combination of two types . In the furnace exit, flue gases produced as a product of combustion, attain a certain temperature termed as furnace exit gas temperature (FEGT).

2018-8-5 · 150,000. The low heat release rate keeps flue gas temperature lower and reduces thermal expansion. A lower flue gas turnaround temperature at the end of the furnace reduces temperature gradient of the tubesheet. This, combined with the reduced thermal expansion of the furnace, increases the tubesheet and tube attachment's life, leading to longer
