In the process of the development of national economy, the importance of boilers is self-evident. The so-called boiler is a device that uses the heat energy released by fuel incineration to heat water or other media, so as to obtain steam, hot water or other media with specific parameters (temperature and pressure).
Water treatment outside the boiler
Before entering the boiler, raw water is treated with water treatment equipment to remove impurities such as hardness, salinity, dissolved oxygen, etc., so that the feed water can meet the water quality requirements specified by steam boiler. Common water treatment equipment includes sodium ion exchange water softening equipment, ion exchange desalination equipment, reverse osmosis water purification equipment and thermal oxygen removal equipment.

The key difference between vapor and steam is that vapor is a generally used term while steam is the technical and specific term. A shared attribute between vapor and steam is the point of origin or how it is formed. Steam and other kinds of vapor are often made by evaporation or with other means or application of heat.
The heat requirements of the building materials manufacturing process are very varied. A steam boiler plays a key role in the process of creating building materials. For example, materials like molded brick rely very much on steam heat from an industrial steam boiler in order to pressurize and harden the elements that make up the brick. Without exposure to that kind of heat and pressure, these materials would be a loose construction of sediment, rather than dependable, solid building components....
When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure equipment, in accordance with local regulations.
1) The entire plant may be purchased as a complete package, only needing securing to basic foundations, and connecting to water, electricity, fuel and steam systems before commissioning. This means that installation costs are minimised.
2) This package arrangement also means that it is simple to relocate a packaged shell boiler.
3) A shell boiler contains a substantial amount of water at saturation temperature, and hence has a substantial amount of stored energy which can be called upon to cope with short term, rapidly applied loads.
*This can also be a disadvantage in that when the energy in the stored water is used, it may take some time before the reserve is built up again.
4)The construction of a shell boiler is generally straight forward, which means that maintenance is simple.
5)Shell boilers often have one furnace tube and burner. This means that control systems are fairly simple.
Although shell boilers may be designed and built to operate up to 27 bar, the majority operat
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
