    Steam Boiler Spare Parts Superheater And Reheater In Thermal Power Plant


    Steam Boiler Spare Parts Superheater And Reheater In Thermal Power Plant

    Product Description

    1Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler.
    2Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency.
    3By 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.

    Characteristics


    1This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat transfer area, reduce the volume, compact structure and reduce the number of elbow and welding to make less leakage and add the heat transfer efficiency.
    2Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall.
    3Widely temperature range, high pressure limit.
    4Durable strong impact, reliable operation.
    5less fume resistance, reduced abrasion and long working life.
    6Beautiful appearance, simple fabrication process.
    7Diverse layout.
    8Ease of installation, ease of construction.
    9A wide range of working pressure .
