industrial vacuum steam power plant boiler
Gas industrial vacuum steam power plant boiler 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.
Similarities and differences vacuum hot water industrial vacuum steam power plant boiler and hot water boiler pressure hot water boiler in this analysis of the current one, the use of a vacuum hot water boiler and pressure hot water boiler are many, then vacuum hot water boiler and pressure hot water boiler What are the similarities and differences between it? Now, Xiao Bian take you a simple analysis. (1) Selection of the auxiliary pressure hot water boiler configuration are relatively stringent, the preferred option, and therefore the probability of failure will be relatively small, and need not maintain a vacuum, simply run under normal atmospheric pressure to , the operation is relatively simple, but relative to its vacuum boiler in terms of some of the more troublesome, but, with the continuous improvement of technology boiler, vacuum boilers now have a breakthrough progress on its drawbacks, at present, two each there are various advantages, specifically how to choose, you need to examine the actual situation. (2) during operation of the vacuum boiler to take into account the degree of vacuum kept, the linkage may be necessary correlation means, the degree of vacuum once damaged, there may occur an accident boiler; and pressure hot water boiler does not have this condition, however, If individual users according to the actual situation, without permission will be under pressure to use pressure hot water boiler, and that their safety is another matter. (3) Origin pressure hot water boiler will be more, and vacuum hot water boiler due to technical applications is relatively new, and therefore, can produce and produce operating thermal efficiency, higher operating level, which is part of the good reputation boiler manufacturers. In short, the process of vacuum hot water boilers and pressure hot water boiler in the running there will be many figured the place, we will naturally have many differences, during boiler selection, take me to their strengths, based on the actual situation, The merit-based election
Vacuum hot water industrial vacuum steam power plant boiler hot water boiler Vacuum Products Products vacuum hot water boiler works in the standard state, the vacuum boiler -76CMHG. After starting the boiler, fuel combustion heat is transferred to the heat medium heating surface of the water, the heat medium water is evaporated in heat exchange between the steam, the heat exchanger increase the vacuum chamber at a negative pressure within the furnace, condensate reflux of water to the furnace, boiler water using the steam phase change heat transfer process interact to achieve, through the phase change of the boiler water, water vapor condensation and evaporation furnace transfer latent heat boiler water to achieve the heat transfer process. Meanwhile, if the working medium of the heat exchanger, using the difference in heating temperature and the flow rate output with special requirements, can be specially designed according to the needs of users, the quality can be delivered on time. Heat exchanger, and the water distributor flange can be designed and manufactured of stainless steel for heat strong corrosive media. For larger heating case, a plurality of parallel operation may be performed, better results than the single-unit operation, better energy saving. The machine is running, a multi-purpose machine, while the need to provide different occasions, no need to install. Vacuum hot water boiler during operation, the internal pressure of the furnace in a vacuum state is always the -15cmHg-76cmHg. Even if the U-shaped heat exchanger leakage due to external pressure, or the operational failure can not exceed the external atmospheric pressure, the controller, the water temperature control, superheat and the vacuum pressure switch will automatically switch off the power. When the pressure reaches 0.025MPa, the safety valve will open automatically to withstand the discharge pressure.
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired industrial vacuum steam power plant boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
