Industrial steam boilers

posted:2019-06-25

   Many people should not know what a steam boiler is? And what is the function of the steam boiler? Industrial boilers are important thermal energy supply equipment in the national economy. In the pharmaceutical, machinery, metallurgy, chemical, textile, paper, food and other industries, steam boilers are required to supply a large amount of heat. A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.h90Industrial Steam Boiler

  Types of steam boiler

  There are virtually infinite numbers of steam boiler but generally they fit into one of two categories: Fire tube or water tube boilers. In fire-tube boilers, combustion gases pass through the inside of the tubes with water surrounding the outside of the tubes. The advantages of a fire-tube boiler are its simple construction and less rigid water treatment requirements. Water tube boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes. These boilers can be of single- or multiple-drum type. These boilers can be built to any steam capacities and pressures, and have higher efficiencies than fire tube boilers.h90Industrial Steam Boiler

  Steam boilers can be classified into electric steam boilers, fuel steam boilers, gas steam boilers, coal-fired boilers, and biomass boilers according to fuel. The high output wns series steam boilers produced by ZBG are made of quality steel and are distinguished by their solid, robust and elastic construction. The boiler is classical 3 pass fire tube boiler with an inner fully water cooled flue gas turning chamber guarantees high efficiency. The boiler consists of a cylindric shell, the two headplates, the centric flame tube including the back flue gas turning chamber with water cooled finned tube wall and the two flue gas passes. The boiler door is thermal insulated and flue gas proof for burner mounting. WNS series oil and gas boiler is a hot product of ZBG, and has been exported to Russia, Australia, Southeast Asia, Mexico, Cameroon and other regions.h90Industrial Steam Boiler

  The function of steam boiler

  Steam boiler is normally used in industrial process heating such as textile factory due to the high energy content of steam. Steam is also used for cleaning applications and turbine-generation. The advantage of steam over hot water is its high energy content and ability to release energy during condensation. This also allows for very small heat exchangers.h90Industrial Steam Boiler
