It is well known that the petroleum and petrochemical industry is inseparable from the use of large-scale steam boilers for thermal energy conversion or filtration use. The reason why steam-type boilers will be selected for processing use. Because not only high thermal energy but also energy-saving and environmental protection can meet the needs of petroleum and petrochemical industry. Professional steam boiler can not only help the petrochemical industry to process smoothly, but also help enterprises to produce huge economic benefits to improve the production of petroleum processing. Let's follow the editor to see why steam boilers are used in the oil industry:
1, it can save processing costs more effectively because steam boilers can save energy and environmental protection in the process of processing and use to reduce power consumption, so the use of the corresponding in the petroleum and petrochemical industry can reduce the larger cost investment. Moreover, steam boilers use electric energy to process and use, so they can effectively save a lot of energy consumption and help enterprises reduce costs. Reducing the cost can be more beneficial to the petrochemical industry to use a large number of processing to improve economic efficiency.
2, the reason why steam boilers are selected for long-term processing and use in the oil industry with high safety and stability of steam pressure is also because steam boilers are stable in operation and can carry out effective range control. Moreover, the boiler can control itself in the safe operation of steam pressure value, and ensure the safety and stability of the equipment in the process of operation. Therefore, it is especially suitable for petroleum and petrochemical industry with large processing capacity and long duration.
3, boiler energy-saving technology highlights that petroleum needs the conversion of boiler thermal energy in the refining and chemical process to carry out normally, and steam boiler has unique energy-saving technology and can automatically feed water through frequency conversion technology. Moreover, the steam temperature and pressure can be automatically adjusted under stable conditions, so it can be more energy-saving and stable compared with the continuous working process, and it can also save energy and reduce emissions while ensuring the normal supply of petroleum processing at the same time.
About hot water boilers including hot water boiler electric water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers that produce hot water boilers, is the use of the thermal energy released from fuel combustion or other thermal energy (e.g., electrical energy, solar energy, etc.) the water was heated to a nominal temperature of a thermal device. "Special Equipment Safety Supervision Regulations" as defined in the boiler is the use of various fuels, electricity or other energy sources, the costumes, the liquid is heated to a certain parameter, and external heat output devices. Which is defined in a range equal to or greater than the volume of the pressure of the china diesel fired steam boiler 30L; outlet pressure is greater than or equal to 0.1MPa (gauge pressure), greater than or equal to the rated power and the pressure of the hot water boiler 0.1Mw; organic heat boiler. From "Special Equipment Safety Supervision Regulations" Uses People's Republic of China: There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can achieve the dual function of bathing and heating using inspection items include: checking in the internal boiler inspection and ready to use, furnace and flue boiler inspection accessories check check, auxiliary equipment automatic control system, check the combustion equipment, check the auxiliary heating surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect causing very serious consequences.
