I have a simple question regarding the classification of boilers
Thread Content
I’m not very knowledgeable:loveliness: I would like to ask what the specific categories are, as well as the advantages and disadvantages of each.
There are several types of this classification, based on factors like pressure and so on-------------; there are too many. You’d better look for the books yourself – typing takes too much time
Classified by use: power station boilers, industrial boilers, domestic boilers； Pressurization levels are classified as: low-pressure boilers, medium-pressure boilers, high-pressure boilers, subcritical boilers, and supercritical boilers ； Classified by water and fire flow: water-tube boilers and shell-and-tube boilers ； Classified by fuel: coal-fired boilers, oil-fired boilers, gas-fired boilers ； Classified by combustion method: layer-fired boilers and chamber-fired boilers.
Boilers can be classified in different ways. Boilers can be classified by purpose into industrial boilers, power station boilers, marine boilers, and locomotive boilers, etc ； Boilers can be classified according to their outlet pressure into low-pressure, medium-pressure, high-pressure, ultra-high-pressure, sub-critical pressure, and super-critical pressure boilers, etc. The current series of power station boilers in China are: medium pressure 3.9 MPa ； High pressure: 10 MPa ； Ultra-high pressure 14 MPa ； Subcritical pressure: 17 MPa. The current series of industrial boilers in China are: 0.5 MPa, 0.8 MPa, 1.3 MPa, and 2.5 MPa. Boilers can be classified into fire-tube boilers, water-tube boilers, and shell-and-tube boilers based on the flow path of water and flue gas; among these, fire-tube boilers and water-tube boilers are collectively referred to as shell boilers. Based on the circulation method, they can be classified into natural circulation boilers, auxiliary circulation boilers (i.e., forced circulation boilers), once-through boilers, and combined cycle boilers. A combined-cycle boiler is composed of an auxiliary cycle boiler and a once-through boiler, including boilers with a low cycle ratio (see power station boilers). Boilers can be classified into room-type burners, stratified burners, fluidized bed burners, etc., based on their combustion method.
Find a book on boiler fundamentals to read; it’s quite simple. :lol :lol
