    Steam drum - Wikipedia

    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.

  • blowdown calculation for boiler - altret


    steam can occur. To prevent boiler tube chocking and overheating of the boiler tubes the blow down is necessary. The blow down is the water removed from boiler to maintain the solids level in the boiler drum. This can be calculated as follows: E = Evaporation or steam generation rate. S = Amount of solids (ppm) B = Blow down (m3 / hr) C = Maximum permissible concentration of solid inside the …

    It includesmost steam boilers, the exception being those of the ‘once through’ or coil type, where there is no steam drum. In such cases, steam outlet temperatures exceeding a pre-set value are taken to indicate insufficient water input. In most cases, the simple gauge glass on the steam / water drum or boiler shell is used as the indicator.
