80 3500kw horizontal natural gas hot water boilers
Common 80 3500kw horizontal hot water boilers Accident (c) hot water boilers common accidents in addition to accidents, explosions, that there is a tube rupture. So what causes hot water boiler tube rupture is what kind of solutions does the cause of the hot water boiler tube rupture:?? Quality (1) boiler water is poor, resulting in the accumulation of impurities in the boiler, severe corrosion and other problems attached boiler tubes, not a long time to clean up in time, lead to the phenomenon of burst pipes. Material selection (2) non-compliance boiler tubes and so lead to pipeline pressure less able to cause the occurrence of burst pipes phenomenon. (3) In addition, due to the boilers used for a long time, parts of aging, wear and other phenomena more serious, there will be burst pipes phenomenon. (4) When pulverized coal boiler, oil, gas hot work, operational errors can cause the collapse of the furnace walls and furnace tube bore explosion. Solution: (1) timely boiler attached to the wall of debris to clean up after the shutdown. (2) severe damage to the superheater, boiler shutdown immediately related operations hot water, and then timely maintenance. In short, boiler tube rupture is one of boiler accident hazards of large accidents, hot water boiler during operation, should be timely maintenance, to avoid unnecessary security risks.
1) checking and cleaning table tube pressure gauge, distilled water reset.
2) maintenance level electrodes, after extraction, polished with fine sandpaper.
3) to clean the flue, generally based on the exhaust gas temperature to determine the need to clean up. In general, the exhaust gas temperature does not exceed 350 deg.] C (at the outlet of the boiler, measured at the inlet flue), represents too increased fouling, reduced boiler efficiency, must be eliminated. On the one hand the purpose is to clean up the flue economic considerations, on the other hand also out of consideration (soot poor thermal conductivity, partial burn-prone) on security. When cleaning up asbestos gasket replacement, to use the wrong method mouth lap (anti-smoke ran out), graphite coating, can not add oil.
4) After the inspection or repair of the boiler, to check the manhole, the first hole, the nut can not be loosened hand hole, to check motor direction (from the fan end, the counterclockwise rotation).
During the training, the participants visited the group to arrange a call center, research and development centers, production workshop, the participants said that through this training visit, the other fast Group's corporate culture, lean management, staff professionalism with a deeper understanding of each other soon Group Technology R & D investment, product quality control, after-sales service system construction with understanding. Participants said that the current visit and study, the other group soon have a new understanding, and trust each other more products faster, this is very good training visits, Hope Group to adhere to gone out of existence. Safety Training Week is running fast party group of service users yet another form, the Group will integrate a variety of services in the form of online and offline, adhere to convenient and efficient service concept, to provide users with the best quality service.
Advantages and characteristics of electrically heated boilers: 1. The high quality heat source heating system can output the hot oil up to 350 ℃ for the thermal user under normal pressure liquid phase. The heating system all adopts Japanese Fuji temperature control instrument, uses the PID self-tuning intelligent temperature control technology, the control precision can reach ±1 ℃, the accurate control temperature range; The main heating power supply adopts solid-state module contactless switching circuit, adapts to frequent switching, and does not interfere with the power supply network. It also has anti-dry burning. The hot oil cooling system can be designed according to the user's requirements to meet the production process requirements of rapid cooling after heating up. 2. Energy saving, low operation cost of heating system is liquid phase closed-circuit circulation, the difference between oil outlet temperature and return oil temperature is 20 ℃ 30 ℃, that is to say, the temperature difference can reach service temperature only by heating 20 ℃ 30 ℃. At the same time, the equipment does not need water treatment equipment and there is no steam boiler running, run, drop, leakage and other heat losses, heat utilization rate is very high, compared with steam boiler, about 50% energy saving; Less investment in equipment because the heating system is simple, no water treatment equipment and more auxiliary equipment, boiler bear low pressure, so the whole system investment is less; 4. Safety because the system only bears pump pressure, heating system explosion-free The explosion is dangerous, so it is safer; 5. The environmental protection effect of environmental protection organic heat carrier boiler system is mainly reflected in the few emissions of flue gas, no pollution and thermal pollution. Characteristics: 1, low operating pressure: liquid phase conveying heat energy, can obtain a higher working temperature under lower operating pressure, heat carrier than the saturated steam pressure of water 70 times lower, the general operating pressure of heating is ≤ 0.3MPa. 2, high heating temperature: heating furnace heating temperature up to 280 ℃; automatic control of heating temperature, high sensitivity, stable heating. 3, safe and reliable: Fangkuai specialized in R & D and production of boilers, with Perfect operation control and safety monitoring device, easy to operate, safe and reliable. 4, environmental protection design: boiler equipment is equipped with a new type of electric heating system, electricity instead of coal, saving investment, environmental protection and pollution-free, at the same time the boiler heating up fast, high thermal efficiency, high efficiency and more economical!
