Sulfur dioxide is a common sulfur oxide, which dissolves in water to form sulfurous acid. When oxidized in the presence of PM2.5, it will quickly and efficiently generate sulfuric acid and cause acid rain. Therefore, the concentration of sulfur dioxide in boiler flue gas directly affects the environment, and is valued by many parties.
How is sulfur dioxide produced in boiler?
The principle of how sulfur dioxide is produced in boilers using different fuels is different. Sulfur in solid ...
As a kind of special equipment, industrial boiler is special and complex. Complete inspection can ensure the safety operation of the boiler.
The external inspection of the boiler is generally conducted once a year, the internal inspection is generally conducted once every two years, and the hydrostatic test is generally conducted once every six years.
For boilers that cannot be inspected internally, a water pressure test should be conducted every three years. The internal ...
The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
The natural gas fired boilers occupy a large proportion of boilers for the industrial and civil uses. They have low energy consumption and can reach the environmental protection standards.
The term “boiler efficiency” is often substituted for thermal efficiency or fuel-to-steam efficiency. When the term “boiler efficiency” is used, it is important to know which type of efficiency is being represented. Why? Because thermal efficiency, which does not account for radiation and convection losses, is not an indication of the true boiler efficiency. Fuelto-steam efficiency, which does account for radiation and convection losses, is a true indication of overall boiler efficiency. The term “boiler efficiency” should be defined by the boiler manufacturer before it is used in any economic evaluation.
The primary objective of an industrial boiler is the generation of steam. Steam is generated by heat transfer at a constant pressure. The fluid, which is initially in a liquid state, is heated, produces a variation in its phase and becomes saturated vapour.
This saturated steam can then be used for different applications such as sterilization, fluid heating or electricity generation.
Water, which is the primary fluid inside the closed metal container of the industrial boiler, is heated to an atmospheric temperature and a pressure higher than the external one. Once the steam is generated, it advances through the pipes.
