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.

Steam generators are used for tea drying

Tea is one of our favorite drinks. The most important process in the tea making process is the drying of tea leaves. These two processes ensure the taste of tea. First of all, the temperature must be accurate, otherwise the fried tea is not cooked evenly, and the temperature and pressure of the steam generator can be adjusted, the steam purity is high, the pressure stability is strong, and the automatic control is more labor and cost saving.

The hot and humid environment provided by the steam generator can promote the chemical reaction inside the tea, making the tea softer and easier to follow the process. Proper steam can promote the transformation and reaction of the substances inside the tea, ‌ releases more aroma components, ‌ makes the tea have a unique and rich fragrance.

Xinda steam generator energy saving and environmental protection, the generated steam can be used repeatedly, not only improve the production efficiency and save costs, but also reduce the pollution to the environment.

How to change the heating tube of the steam generator

Step 1: First cut off the power supply to ensure safe operation. The wiring mode of the steam generator heating tube can be taken with the mobile phone in advance for reference for rewiring after replacement, and then loosen the heating tube connection line.
Step 2: Drain the sewage from the generator before officially replacing the damaged heating tube.
Step 3: After the sewage is exhausted, use a wrench to unscrew the heating pipe and remove the damaged heating pipe. Then clean up the residue inside the generator. After the residue in the boiler is treated, smooth the surface of the connecting port with coarse sandpaper to ensure that the connection is tight and watertight.
Step 4: Smooth the surface of the connection with coarse sandpaper to ensure tight connection without water leakage.
Step 5: Tighten the screws, connect the wires in the correct way before, and check and reinforce the screws at the connection frequently.
Step 6: After the connection is completed, check the voltage at the steam generator switch with the multimeter to ensure that the input voltage is correct, check and strengthen each connection.
