    Natural Circulation Power Plant Boiler Steam/Water Drum for Industrial Boiler High Pressure


    High Pressure Boiler Steam Drum For Industry Use Natural Circulation


    Product Introduction




    The boiler headers have water wall header, superheater header,economizer header and so on, it acts as collection, mixture, re-distributing working medium, as the structure, it can be classified as the end cover type( end enclosure) and necking down type.

    The header is consisted of header body ( large diameter seamless steel tube ), end cover ( enclosure ) , tube joint, hand hole, thermomter socket and so on. And the welding checking is strictly proceeded as the welding process to guarantee 100% qualified products.

    Steam drum is a cylindrical pressure vessel used in water-pipe boiler for steam separation and steam purification, forming a water circulation loop and storing pot water. Its main function is to receive water from economizer, separate steam from water and supply water to circulation loop, and transport saturated steam to superheater. There is a certain amount of water in the drum, which has a certain amount of heat and material savings. When the working conditions change, the speed of vapor pressure change can be slowed down. When the water supply and load are not coordinated for a short time, it plays a buffer role. The drum is equipped with internal devices for steam-water separation, steam cleaning, medication in the pot and continuous sewage discharge to ensure steam quality, as shown in the figure.


    Steam drum is the most bulky and expensive thick-wall pressure-bearing component in boiler. The drum not only withstands high internal pressure, but also produces thermal stress due to the fluctuation of wall temperature due to the change of operating conditions. Therefore, the working conditions are bad, and effective operation condition supervision is needed.


    Working Principle


    • Steam drum is the connecting hub of three processes of heating, evaporation and overheating in the boiler. There is a certain amount of water in the drum, so it has a certain heat storage capacity.
    • When the working conditions change, the speed of steam pressure change can be slowed down, which is beneficial to operation regulation, and thus the safety of operation can be improved. The water heated by water wall is separated by cyclone separator in the drum, and the steam kinetic energy is reduced. The separated steam is separated again through the upper shutter separator. Finally, the water and salt are removed through the corrugated plate before entering the superheater.
    • Evaporation mostly occurs at the gas-liquid interface, so the surface contains the most salt, and there are joint rows to prevent the drum from filling up with water, so there are accident drainage pipes inside. When the water level exceeds the limit, the excess water can be automatically opened and released, but it is not at the lowest point, because it is afraid of drying pot, so it is generally installed at the normal water level.

    Features


    1. Chinese Famous Brand.
    2. Premium Quality, Competitive Price.
    3. Fast Delivery, Excellent After-sale Service.
    4. Certificate ISO9001, ASME, ISO14001, SGS.
    5. Compact structure, easy to install.
    6. The exhaust gas passes through the force convection tube bundle, improving the efficiency of the boiler.

    Accessories


    (a) The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump.

    (b) In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions.



    Functions


    The main functions of drums are:
    1. It is the junction hub of three processes of working medium heating, evaporation and superheating to ensure the normal water circulation of boilers.
    2. Inside, there are steam-water separator and continuous blowdown device to ensure the quality of boiler steam.
    3. Have a certain amount of water, have a certain capacity of heat storage, ease the change speed of vapor pressure;
    4. The drum is equipped with pressure gauges, water level gauges, accident discharge water, safety valves and other equipment to ensure the safe operation of the boiler.
