    ASME Standard High Efficient Steam Hot Water Boiler for Industry and Power Station

     

    Product Introduction

     

    Steam boiler refers to the water heated to a certain parameter and the production of high temperature steam industrial boiler, water in the pot tube heat into steam, fire in the furnace heat, is the principle of steam boiler.Steam boiler belongs to special equipment, the design, processing, manufacturing, installation and use of the boiler must be subject to the supervision of the technical supervision department, the user can only obtain the boiler use certificate, can use the steam boiler.

     

    Advantages 


    • The shorter path of water supply to the riser tubes leads to faster and more reliable operation on different loads and a quick start up.

    • Low risk of Foaming . As the water and the steam-water mixture which is fed into the drum maintains the same and constant level all the time leaving the space above water level in drum ( please refer to the schemactic diagram pic).

    • Quick load variations and reliable operation in variable loads and at any significant change in pressure as the water level in the drum is stable and remains inaffected from turbulence.
    • Less steel is needed as there is no lower boiler drum and moreover the absence of lower drum eliminated unwanted thermal stresses.

    • Self supporting construction by the four downcomers.

    • It can expand from the base in all directions and adapt to different operating conditions.
    • The thermal expansion is from top to bottom and with the usage of grate firing the grate firing the thermal expansion difference is minimised there by manifesting the sealing between grate and the boiler.

    • It can be coupled with Concentrated solar power plant (CSP) as well in order to have increased efficiency ( above 33%) where the main fuels are Biomass, Landfill gas and Wood.
    • Construction and arrangement of heating surfaces is flexible as water can be supplied directly from the drum which is placed quite far away from heating surfaces.
     

    Working Principle

     

    Heating equipment (burner) release quantity of heat, heat transfer by radiation is absorbed by water wall first, water wall of water boiling vaporization, produce a large amount of steam into the steam drum for separation (except dc furnace), saturated steam into the superheater, isolated by radiation and convection way continue to absorb the chamber at the top and horizontal flue, the tail of the flue gas heat, and to achieve the required working temperature in superheated steam.
    The boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work. The reheat steam from the reheater goes to the middle and low pressure cylinder to continue to do work and generate electricity.
