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.
The manufacturers with different scales will have different price policy on the natural gas boilers. The prices of natural gas steam boilers in some large boiler enterprises are higher, while those in some small enterprises are lower. The difference lies in the raw materials, the production process, the quality of employees, and the service management of the company.
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
Make-up water rate refers to the proportion of treated water added to the boilers, steam turbine equipment and its thermal systems and participating in the circulation of steam-water systems in the boiler steam volume in the calculation period.
Removal of metallic scale and corrosion products generally requires chemical cleaning. Acid or chelant cleaning procedures vary greatly depending on individual circumstances. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
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).
