The steam cylinder is the main auxiliary equipment of the boiler, which belongs to the pressure vessel. The main function is to distribute steam, and there are multiple seats on it to connect the main steam valve of the boiler and the steam distribution valve, so as to distribute the steam of the steam cylinder to the required place. The accessories of the sub-cylinder include cylinder body, head, flange, safety device, support.
The working principle and advantage of economizer
The economizer is installed in the lower part of the flue at the tail of the boiler, and the working principle is to recover the waste heat in the flue gas through heat exchange, thereby improving the overall thermal efficiency of the boiler.
When the flue gas passes through the economizer, the heat is transferred through the metal wall to the water in the pipe, thus heating. This heated water is returned to the boiler, which can greatly improve the combustion efficiency, reduce fuel consumption, and thus achieve the role of energy saving and emission reduction.
Main advantages of electric steam boiler
The following is a small series to introduce the advantages of electric steam boiler:
1. Small footprint, compact structure, convenient installation and transportation
2. Automatic control system, equipped with water level control system, pressure protection system and other multiple protection systems, to ensure the normal operation of the boiler.
3. The boiler body is made of high quality steel, high strength and durable.
4. Quick assembly factory, just install water and electricity can be used, simple and convenient.
How to choose a hot water boiler?
Hot water boilers are closely related to people’s lives and are used in heating and showers. And there are many kinds of hot water boilers on the market, and the choice of a good hot water boiler has been troubling many people. Today, Xinda boiler will introduce you how to buy a better hot water boiler.
1. Intelligent control system, with high pressure protection, water shortage protection and other multiple protection systems, safe and reliable;
2. High quality burner, durable, full combustion, low noise;
3. The boiler uses a new type of thermal insulation material, good thermal insulation performance, greatly reducing the heat loss of the furnace body, and the thermal efficiency is as high as 90-94%
4. Superb welding technology, solid and durable furnace body.
Autoclave
Autoclave is a common pressure vessel and belongs to special equipment. It is widely used in the industrial field, mainly for the material treatment in the process of heating, evaporation, concentration and drying. Its main structure is generally composed of autoclave body, conical cover, heat transfer plate and support frame.
The working principle is to use steam heating to process the heated material. During the heating process, steam enters the tank through the steam valve. Heat is exchanged with the material on a heat transfer plate to heat the material to the desired temperature.
Steam generators need attention to water level problems
When the steam generator is running, it is necessary to maintain the normal water level, and too low water level is easy to cause dry burning of the boiler, which will cause serious accidents. The high water level will cause the steam to take away a lot of water when the steam generator is removed, which will make the steam quality worse, so the water level should be strictly controlled.
Causes and treatment measures of steam generator scaling
We use the steam generators for a long time will scale, even if there is no too thick scale, it will greatly reduce the thermal efficiency of the boiler, not only waste fuel, but also affect the service life of the steam generator, and even occur safety accidents. So we need to clean the scale on the steam generator regularly.
After we have used the steam generator for some time, it is necessary to check whether the steam generators have produced scale. It is recommended to install a water softener in front of the boiler. It can effectively reduce the hardness of the water, thus extending the service life of the boiler.
We can alkali wash or acid wash the boiler regularly. Alkaline washing is the use of caustic soda and other alkaline drugs to clean the furnace. Its function is to loosen scale and promote it to fall off. Acid wash is the use of hydrochloric acid and corrosion inhibitors to clean the liner, and then combined with alkali boiling. But hydrochloric acid is corrosive to metal, so be sure to pay attention to the amount of hydrochloric acid.
Why do many people buy steam generators?
First of all, we first understand the difference between steam generators and boilers, steam generators are small inspection free boilers, working principle and boilers, are the use of energy (fuel and other energy) to heat water to produce steam mechanical equipment. The pressure of the steam generator is small, small and convenient, and will not take up too much space. Secondly, the steam generator is relatively low in cost compared to the boiler, and it will not cause too much economic pressure for small businesses and users.
Xinda steam generator adopts intelligent control system, automatic operation, automatic water supply, low pressure automatic work, high pressure automatic stop, safe and reliable, saving time and labor.
Boiler unit conversion
1.kcal: heat unit, refers to one of the output units of hot water boilers, expressed as “Kcal/ hour (Kcal/h) .
2.Boiler evaporation is the amount of water that turns into steam per hour: tons/hour (T/h) or kg/hour (Kg/h).
A ton of boiler can turn a ton of water into steam every hour. In China, the corresponding relationship between the evaporation and power of steam boilers is: 1T/h=1000kg/h=0.72MW=720kW≈955Hp (horsepower) 1MW=10*6W 1kW=1000W 1Hp =0.745kW 1 ton/hour (t/h) ≈60×10^4 kcal (kcal)/hour (kcal/h) ≈ 0.7MW ≈720K KW (KW)
3.The tonnage of the boiler refers to the heat sent out by the boiler per hour, which is equivalent to the heat of the saturated steam in tonnage.
4.1 mw(h) =1000 kw(h), 1 kw(h) = 1000 w(h), 1cal= 4.18j, 1 kcal = 4.18kj, MW is the power of a boiler.
Factors affecting the life of steam generators
With the continuous progress of science and technology, many places in various industries need to use steam generators. Then after the boiler indicators have met the requirements, the service life of the machine has become a problem that we have to consider, so in order to extend its service life, what do we need to pay attention to? Follow us to understand together.
Manufacturer: The details of the manufacturer will affect the overall quality and service life of the steam generator, and high-quality boiler accessories will greatly improve the service life of the steam generator. Strictly control the production quality, will greatly improve the service life.
Heat pipe: heat pipe is the core parts of steam generator, high quality heat pipe can greatly improve the life of the whole steam generator.
Operation: During the operation of the steam generator, be sure to follow the correct steps to use the steam generator.
