Water Tube Boiler Furnace Temperature


Prediction of risers tubes temperature in water tube boilers

Mar 01 2009 · Furnace heat is supplied across the risers walls to the rising fluid inside the tubes. Thus steam starts to form inside the risers tubes. The steam-water mixture is less dense than the saturated water at the tubes inlet. Therefore fluid flows upwards in the risers tubes back to the boiler drum.
