  • What is boiler

    Heat Transfer In Steam Boiler. A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.

  • Steam drum - Wikipedia

    2021-8-31 · A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the 'hotter'-water/and saturated-steam into the steam-drum.
