What are the advantages of vacuum fired vacuum boiler supplierss?

Because the inside of the furnace is a vacuum, the heat medium condenses onto the heat exchanger after it is heated and evaporated, so the heating medium is no more than the heating medium in the process of use. At the same time, it is more energy-saving and environmental-friendly than other types of boilers. Do you know what are the main advantages of the most reliable vacuum boiler? Here is a brief introduction to the advantages of vacuum boilers.

1, high efficiency and energy saving because the vacuum negative pressure hot water technology is used in the production design of the vacuum boiler, so it can make the boiler run in the vacuum state, and its boiling point is low, and it can carry on the latent heat exchange of vaporization (condensation latent heat). And using the three-way wet back design, the heat transfer performance is good and can effectively improve the radiation and convection heat transfer area, so it is more efficient and energy-saving.

2, multi-purpose because vacuum boilers are not only divided into vertical, horizontal, fuel and gas and many other models that are freely available to the user, but also because its heat exchanger and header are a separate state. Therefore, the load of heating water and hot water can be switched at any time according to the actual needs, which can fully meet the different requirements of users for heating water and clean hot water, and ensure that hot water is clean and stable so as to realize multi-use of one machine.

3, the installation is simple because the vacuum boiler is manufactured with modular design and high-performance heat transfer components, so the unit size of the boiler is smaller. It is not only convenient for transportation and storage, but also simpler and more convenient in installation method. In addition, it can also be conveniently installed in a small space or can be used in parallel operation of multiple units according to the actual needs. These three parts are the main advantages of vacuum boilers.

Gas fired vacuum boiler suppliers vacuum boiler describes a vacuum heat medium to rely on evaporation and condensation boiling mass transfer heat exchanger to heat the feed water heat exchange apparatus. Of water at different pressures, different boiling points. Atmospheric boiling point of water is about 100 ℃, and its boiling point at a pressure only 7mmHg 5 ℃. Vacuum boiler working pressure range of 200mmHg-500mmHg, corresponding to the water temperature was 66-90 ℃. Vacuum boiler composed of two parts evaporator heat exchanger and the condensing heat exchanger. An evaporator heat exchanger and the combustion boiler is provided with convection heating surface, fuel released by combustion heat of the heat-generating medium the corresponding saturated vapor pressure. Vapor rises to the condensation in the condenser section is condensed releasing latent heat of vaporization to transfer heat to the heat exchanger for hot water, the hot water heated to a certain temperature to the heat user, the condensed condensate returned to the evaporator transducer vaporization heat in the evaporator, this cycle continuously supplying heat to the outside world. Safe and reliable: Vacuum boiler always run under negative pressure, no danger of explosion, part of a separate heat exchanger can be pressure 1.6MPa pressure, and stable operation, a significant feature of atmospheric pressure boiler and can not be compared. Efficiency: self-developed integrated heat storage cluster rotation and multi-zone multi-chamber heat exchanger technology, a substantial increase in thermal efficiency, the left and right exhaust gas temperature 100 ℃, than similar fuel gas boiler energy saving up to 25%. Durable: indirect heating method of production of hot water, hot water and the heat medium independently, to avoid fouling the machine body (water side heat medium), the vacuum furnace body and the furnace oxygen-free environment to eliminate oxygen corrosion in vivo, combined with self-developed double buffering module flat conducting structure, thus extending the life of the boiler. Multi-purpose: to provide simultaneous multiple different temperatures of hot water, to meet the various needs of users central air-conditioning, heating, sanitary hot water, high-level swimming pool, guest houses, hotels and other hot water supply, process water is also available for all types of industrial and mining enterprises . Ultra-fast: the ignition system to work about 20 minutes. Set diverse places: the installation location choose basement, floors, intermediate floors and roof, etc., saving the land for construction. No need to qualification: the boiler is not a "boiler and pressure vessel safety regulations," the specified range, without operator qualification. Automatic Temperature Control: the hot water outlet temperature can be freely set in the range ≤90 deg.] C, the microcomputer energy can be automatically adjusted according to the heat load, the hot water temperature control in the most optimal state. System design is simple: the hot water heat exchanger by indirect heat medium heating water directly supplied to the user, the system can reduce the heat exchangers and other components, making the system simpler design. Simple operation and maintenance: vacuum hot water boiler control microcomputer Chinese man-machine dialogue, to set free the opening, off time, stepless temperature setting switch with removable water heating system configuration, while the front opening, the smoke box structure, and all of the smoke tube joints can be visible and easy inspection, maintenance. Environmental compliance: the design of the boiler using the burnout rate and the rate of heat transfer multi-zone multi-room eddy current rotary heat exchanger technology to improve fuel gas, with imports of brand-name European burners, fuel combustion more fully, low noise, NOx emissions a minimum amount in the same boiler, in full compliance with increasingly stringent environmental requirements.

Boiler feed water preparation device preparing process advantages and disadvantages current power fired vacuum boiler suppliers 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.
