Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
It is necessary to confirm whether the boiler pressure is correspondingly higher when steam is not used and lower when steam is used. This is mainly due to the different water pressure and volume under different pressures.
During the operation of automatic boiler water softener, the role of salt is to backwash sodium ion resin to prevent the sodium ion resin from being poisoned by iron, so the salt will not be destroyed during operation. Pay close attention to the salt content in the salt tank. As long as the salt is continuous, there is no requirement for the salt content. However, for good control, the amount of salt is generally about two-thirds of the salt tank, and then filled with water.
In recent years, the state has stepped up efforts of prohibiting the traditional coal-fired boilers. Major enterprises keep up with the times and purchase various environmental protection boilers. Gas-fired boiler is currently the most popular environmental protection boiler. However, due to geographical limitations in some areas, natural gas is difficult to obtain, or the cost is too high, some enterprises will choose biomass steam boilers.
Recently, some users have come to consult how to solve the ash leakage at the expansion joint of boiler flue outlet. ZOZEN Boiler suggested that in case of ash leakage from the expansion joint at the boiler flue outlet, please contact the professional industrial boiler manufacturer.
Boiler safety accessories are indispensable parts of boiler operation, mainly refer to accessories such as pressure gauge, water level gauge, safety valve, steam-water valve, sewage valve, etc. These accessories are extremely important to the safe operation of boilers, especially pressure gauges, water level gauges and safety valves, which are the basic accessories for ensuring the safe operation of boilers. Therefore, they are often referred to as three safety accessories of industrial boilers.
First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.
Boiler antifreeze, as its name implies, is a kind of regulator that can prevent the water in the boiler or boiler circulation pipe from freezing and inhibit the formation of scale. Boiler antifreeze contains a special corrosion inhibitor, which can be used and stored for a long time, keeping its characteristics unchanged, and will not damage the metal parts of the boiler.
