Price Price hot water boiler hot water boiler: gas vacuum hot water boiler use of the characteristics of different water pressure environment of different boiling points. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler operating pressure in the range -0.07Mpa less. Corresponding boiling temperature of water is less than 93 deg.] C, vacuum gas at the operating pressure of the hot water boiler, the combustion temperature rises to the water boiling temperature, the steam boiling surface to produce the same temperature, volatile vapors absorb large amounts of heat. At this time, water is injected into the heat exchanger of the boiler. After the inner tube was heated to an outer cold administered heated steam flows out through the steam pipe outside the cold water cooled heat exchanger is condensed into water droplets, the water cycle is completed in vacuo. 1. smoke tube was added in the process, improve the heat transfer effect of making the arrangement more concentrated. With a square overall structure independent spray, beautiful shape of the separation. three. Large furnace techniques: effectively increasing the heat radiation area of ​​the unit, to reduce the nitrogen oxide emissions. 4. Boiler water using a high water to ensure that water within the boiler fouling and not oxidized. All wet back shell type three-way structure, static heating, excess heat .6, actively control the whole system, it does not require special duty. Seven. Unique pulse level detection circuit having a reliable performance. 8. inlet / outlet temperature display easier to control the operation of the vacuum and hot water boiler operating segment. 9, receiving advanced multilayer insulated glass wool, heat loss is small. Henan fast boiler gas hot water boiler with three vacuum pressure safety system: automatic safety explosion-proof valve in the discharge control: when the internal pressure of the boiler continues to rise, the explosion-proof valve due to EHV broken, releasing the pressure inside the boiler, to ensure safe operation of the boiler; 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, side off: opening vent automatic safety alarm: the boiler when the internal pressure becomes slightly positive, automatic vibration security alarm explosion-proof valve, cutting off the power boiler.

Steam electric boiler maintenance and fast boiler pump classification Henan Xiao Bian told you about the company's steam boiler maintenance and electrical vacuum pump steam boiler maintenance classification should pay attention to 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve. The vacuum pump is divided according to use: a roughing pump starts to decrease from atmospheric pressure to a vacuum pump system to work the other pumping systems. 2. High vacuum pump operating in a high vacuum range. 3. The main pump in the vacuum system, the vacuum pump used to obtain the desired degree of vacuum. 4. foreline pump foreline pressure is maintained for a further vacuum pump in which a pressure below the critical backing. 5. coarse / low pressure pump starts from the atmosphere and for obtaining a low degree of vacuum of the vacuum pump. 6. The booster vacuum pump is mounted between the low and high vacuum systems to improve the efficiency or reduce the vacuum foreline pump capacity requirements. 7. The ultra-high vacuum pump works in the ultra high vacuum range. 8. A pump is maintained in a vacuum system, when the gas amount is small, can not be effectively utilized master, before the pump, In this case, with a smaller capacity auxiliary backing pump to maintain the main pump containers or maintain a desired degree of vacuum . Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!

Dongying City, Shandong Province in response to low-nitrogen coal-fired boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.

Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.

After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.

Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.

According to statistics, this year the city of Dongying city plans to add a total area of ​​clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.

Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.

Care must be taken when using the introduction gas steam boiler summary of some of the products despite stable and safe operation, but the use of gas steam boiler should be very common. But by no means is that you can manipulate it at will. This time we will introduce the use of some of the summaries must consider when gas steam boiler. First, double-check before starting boiler gas steam boiler is very important. The review process is very important. We must examine these parts. For example, the gas pressure is reasonable, whether the windshield of the flue gas duct is open, and whether the vacuum pump is pumping. Normal and so on. Only when the equipment is in good condition to start the boiler, and can be operated security of each steam boiler safely. Secondly, the use of off during the shutdown should be a very rigorous process. First of all, the fire should be turned into a small fire, then slowly goes out, turn off the burner. There should be a lot of summaries on the safe use of steam boilers. If you can pay particular attention to the use of so many summary, I believe that the use of a steam boiler is very safe, in order to avoid improper use of details. When the water level falls below a predetermined minimum water level, but when the water level observer can still see the water level, water temperature is determined to be insufficient; when the water level measurement water level measurement project is not judged to severe water shortages. This phenomenon will include summarized as follows: (1) the drum water level is less than a predetermined normal level; (2) low water level warning audible alarm automatically, bright lights; (3) steam superheated steam temperature increases; (4) Water not normal, lower than the steam flow rate value; (5) steam exhaust gas temperature.
