Boiler Supplier

Fourth, the vacuum hot water boiler mainly take the form of indirect heating boiler, mutatis mutandis, external heat exchanger and circulating water pump in the overall installation cost can save a large part; also has a fast heating, high efficiency and good heat characteristics, to a large extent for the user to save fuel costs.

Which of the atmospheric or vacuum or hot water boilers needs to be discharged? Atmospheric pressure boilers and vacuum boilers in gas-fired hot water boilers, which require sewage discharge operation in the course of operation, are for atmospheric pressure hot water boilers, and vacuum hot water boilers do not need to do this work because: atmospheric pressure hot water boilers, All the system water enters the boiler, and the boiler burns high temperature water. After the treatment of the soft water equipment, the system can only remove most of the calcium and magnesium ions in the water, but a small amount will enter the boiler. Therefore, when the calcium and magnesium ions reach a certain concentration, it is necessary to carry out the sewage discharge operation in order to avoid the boiler operation problems due to the existence of these ions.

Lujiang County, Anhui Province People's Government to strengthen the special equipment safety supervision, eliminate security risks, protect people's lives and property safety, recently, market supervision arrangements father of the rule of the mountain to carry out a special inspection of the boiler.

The area under the jurisdiction, boiler unit 10, involving 13 sets of boilers, mainly for industrial enterprises, food production enterprises. The audit focused on with the operation of the boiler, the boiler nature of the situation (coal, electricity, gas, biomass, etc.), verification test cases, water quality monitoring, troubleshooting, case workers certified, the implementation of the system, etc. . Examination revealed there is some use of units overdue inspection, the main responsibility is not implemented and so on, law enforcement officials immediately issued special equipment safety supervision instructions, the use of units ordered to stop using, to urge the rectification.

Vacuum boiler vacuum boiler price Price: Vacuum gas boiler with water to work in different environments and different pressures boiling point characteristics. At normal atmospheric pressure, the boiling point of water is 100C, vacuum gas hot water boiler working pressure range -0.07MPa less. Corresponding to the boiling temperature of water at 93 deg.] C or less, at the operating pressure vacuum gas hot water boiler, the combustion temperature of the water rises to the boiling temperature, the same temperature of the steam generated in the boiling water, evaporated and absorb large amounts of heat. At this time, injecting water into the boiler heat exchanger, the outer tube by the inner tube steam heating the cold water flowing into the hot water, and cold water outside the pipe after cooling steam condenses into water droplets, thereby completing the water cycle in vacuo. 1, built-in smoke tube flow, increasing the heat transfer effect, make the layout more concentrated. 2. With a square overall configuration, the individual sprays, beautiful appearance. 3. hearth technical measures: increase the effective area of ​​the unit radiant heating, low NOX emissions. 4. Boiler water with high water, to ensure that water does not scale furnace, no oxidation. 5. Use case, the disk structure all wet back three times, static heating, excess heat. 6, all active control system, no staff on duty. Singular pulse level detection circuit 7. The structure, reliable performance. 8, the inlet / outlet temperatures can be easily fragmented display control operation of the vacuum hot water boiler. 9. Advanced multilayer centrifugal glass wool insulation, heat losses are small. Zheng Pan gas hot water boiler receiving three vacuum pressure safety system: automatic safety explosion relief valve: When the boiler pressure increased pressure, excessive pressure, the explosion-proof valve is broken, the pressure is released from outside the boiler, the boiler in order to ensure safe operation; a digital pressure switch: imported from Japan digital pressure switch detecting a change in the pot at any degree of vacuum, when the pressure is too high, end off; explosion-proof safety valve alarm automatic control: when the pressure in the boiler when the steering slightly positive vibration proof safety valve automatic alarm, blocking power boilers;
