    5/11/2018 · The heat flux density in the zone of maximal heat loads at a height of 12–16 m in the TGMP-204-I boiler firebox is by 200 kW/m 2 lower than it is in the TGMP-204 boiler firebox. As a result, more uniform steam generation is obtained in all tubes of waterwall surfaces over the firebox perimeter.

  • TUBES AND TUBE BANKS, BOILING HEAT TRANSFER ON

    Since 1829, when George Stephenson first boiled water on the outside of a tube bundle in his "Rocket" locomotive, boiling on the shell-side of bundles has been a common process in the power and process industries. Fire-tube and waste heat boilers which raise steam from hot gases generally have well spaced, large diameter tubes and the primary resistance to heat transfer is on the gas side.

  • Thermodynamic Design of a Fire-Tube Steam Boiler

    Fire­tube steam boilers are designed for the purpose of industrial scale heat exchange in order to heat saturated liquid entering the control volume to a saturated gas. Exiting gas leaving the control volume may experience a pressure drop when returning to atmospheric pressure. Fire­tube steam boilers are composed of a cylindrical hull filled with thermal insulation in which a series of tubes are contained. Hot air from a burner is passed from a furnace in the 1st pass to a series of tubes in the 2nd pass, then to a series of tubes in the 3rd pass. Finally, the hot air exits through a chimney. The boiler is filled with water up to the top level of the 3rd pass pumped from the base of the boiler. Steam is then pumped from the top of the boiler to wherever heating is needed. The boiler contains a safety valve that, when the pressure becomes too high due to blockage or overheating, releases the excess steam.
