Vacuum boiler works, features and advantages: vacuum steam boiler equipped with a temperature controller system and a security alarm system is set, when the temperature reaches the set boiler stopping the machine control system will automatically cut off the electrical and gas systems, and issues Audible alarm. Any of a vacuum boiler vacuum gauge, a vacuum switch, a vacuum pump monitoring system, the flue gas temperature sensing probe, etc. abnormal, the control system will automatically cut off the electrical and gas systems, with sound and light alarm. Vacuum adsorption boiler is equipped with a safety valve, start overpressure, to achieve the purpose of safety relief. Preventing overheating protection device, when the boiler temperature exceeds 100 ° C, automatic fuse protection device, the gas system and cut off the circuit, so as to achieve a safety pressure relief, the working principle of vacuum boiler water at atmospheric pressure (1bar), boiling point of 100 ℃. Pressure below 1bar, the boiling point of water becomes less than 100 deg.] C; pressure -0.7bar, a boiling point of 90 deg.] C; pressure -0.3bar, a boiling point of 70 ℃; pressure -0.1bar, a boiling point of 40 ℃ vacuum hot water unit. after the hermetic chamber is formed by a vacuum pumping the vacuum chamber, the combustion heat medium boiling water vapor generates a negative pressure in the vacuum chamber, the vapor condenses in the external heat exchanger, the heating temperature and the cold water pipe to the user through the water after the vapor condenses to form water droplets flow back into the heat medium water, re-heating evaporation, thus completing the cycle, the unit is less than the normal operating pressure -0.7bar. Heating medium water is treated by a special cleaning, deoxidation high water, washed once injection is completed before delivery from the factory, in a closed loop inside the unit during use (evaporation - condensation - vaporization), not increase, not decrease, the unit life without need to be supplemented or replaced.

Many users in the purchase of the boiler, the boiler type for "vacuum boiler" always have doubts, do not know what the concept of the boiler, can you use in your enterprise. Fast boiler manufacturers come to tell you about, what the vacuum hot water boiler Yes.

Boiler feed water preparation device preparing process advantages and disadvantages current power boiler feed water system ultrapure water substantially above three processes, rest of the process are carried out with different combinations of the three basic process on the basis of the above derived. Their disadvantages are now listed in the following: 1, a first ion exchange resin is advantageous in that low initial investment, space occupied, but the disadvantage is the need for frequent regeneration of ions, pH-consuming, but also for the environment certain destructive. 2, the second stage reverse osmosis equipment, which is characterized by the early administration level attained manner using ion exchange resin is higher, but without resin regeneration. The disadvantage is that the original film is related to be cleaned or replaced regularly, the water quality is not too high, relatively speaking, most can do about 1us / cm. 3, the third reverse osmosis for pre-matched electro-deionization (EDI) apparatus, which is ultra-pure water system to take the preparation of ultrapure water most economical and environmentally friendly, it does not require regeneration with acid continuous Preparation of ultrapure water, no environmentally destructive. The disadvantage is that the initial investment is relatively above two methods are too expensive. High-pressure boiler feed water treatment equipment for industrial and mining enterprises and medium-sized thermal power plant and boiler feed water treatment. The world's most advanced reverse osmosis membrane element, pressure vessels and other equipment, supported by reasonable and have a pre-processing and post-processing equipment, can produce boiler feed water in line with national or industry standards (GB1576-79, DL / T561-95) super pure water. In the membrane treatment system, used typically ultrafiltration pretreatment 1mm diameter hollow fiber, to remove suspended solids and colloids in raw water, the biggest problem is the pretreatment as UF membrane fouling and membrane clogging for this often provided at the front pre-filter, to remove large particle suspension was pre-filtered before flocculants, such as PAC (poly acrylic acid) can improve the filtration quality, and reduce the membrane resistance. The amount of dissolved oxygen to the boiler feed water system of the plant required for the general requirements 0.3mg / L or less, for degassing membrane should be operated at a vacuum of less than 5.33Kpa (40TORR) a. IPC programmable control system control, automatic start and stop, dosing and flushing, automatic monitoring of various operating parameters, for production management.

The theme of the conference is "clean low-carbon, Better Life", which is fast adhering to the party's "build clean fuel gas-fired boiler" concept coincide. After this symposium, party fast more clearly the future direction of development in the field of cleaning boilers, adhere to the road of independent research and development of new technologies, increase investment in research and development funds, is committed to develop cleaner and more environmentally friendly boiler equipment, "blue sky project" to make its own contribution!
