    PACKAGED – TYPE BOILERS
     
    Packaged-type Boilers are of watertube design with a water natural circulation through the boiler. They consist of two drums interconnected by tube banks and bounded by tube walls in membrane construction (tube-fin-tube).
    The are of three-pass design in horizontal flow. A water heater is placed in a smoke duct above the drum, within the third pass.
    The boiler structure is self-carryng, mounted to a base frame.
    The boiler combustion space, at the smoke side is of an over-pressure design. With greater units, the tube walls recive forces due to the over-pressure by horizontal buckstays. APPLICATION

    • auxiliary and peak boilers in power production and distribution
    • for generation of processing steam in industry
    • for giving of smaller turbines

    FEATURES

    • modern design – high efficiency – simple operation and maintenance
    • high boiler capacity combined with small dimensions – possibility of building into existing objects
    • simple foundation – minimum cost of building work
    • easy transportation, quick erection – boilers are shop assembled
    • short start-up time – flexibility in operation
    • forced draught of flue gases – more economical operation
