    Stainless Steel Boiler Economizer Bare Tube Type With Headers On Painted SCR System Recovery Flue Gas

    Stainless steel economizer bare tube type with headers on painted SCR system recovery flue gas

    Product Description


    ·Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler.

    ·Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency.

    ·By rapidly increasing feedwater temperature through captured flue gas, economizers also provide a significant improvement in steam generation and response time.


    Technical specifications

    Material Structure
    Consists of a serious of spiral fin tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.

    Structure Arrangement
    In line / staggered arrangement.

    Cooler Economizer


    · A common form of refrigeration economizer is a 'walk-in cooler economizer' or 'outside air refrigeration system'.

    · In such a system outside air that is cooler than the air inside a refrigerated space is brought into that space and the same amount of warmer inside air is ducted outside.

    · The resulting cooling supplements or replaces the operation of a compressor-based refrigeration system.

    If the air inside a cooled space is only about 5ºF warmer than the outside air that replaces it this cooling efferct is accomplised more efficiently than the same amount of cooling resulting from a compressor based system.

    · If the outside air is not cold enough to overcome the refrigeration load of the space the compressor system will need to also operate ,or the temperature inside the space will rise.

    Internal heat exchangers


    1.Subcooling may also be produced by superheating the gas leaving the evaporator and heading to the gas compressor.

    2.These systems withdraw heat from the liquid line but heat up the gas compressors suction.

    3.This is a very common solution to insure that gas reaches the compressor and liquid reaches the valve.

    4.It also allows maximum heat exchanger use as minimizes the portion of the heat exchangers used to change the temperature of the fluid,and maximizeds the volume in which the refrigerant changes its phase.
