Boiler boiler protection system has high pressure, ultra-low protection. When the supply voltage exceeds the normal range, automatically cut off the boiler supply and alarm. The boiler has a temperature sensor fault protection, each boot, boiler control system first detects (http://www.chemdrug.com/sell/76/) sensor condition, such as abnormal boiler is automatically cut off power and alarm. Boiler water alarm has the features: the boiler when the boiler water level is below the safety level, the boiler power is automatically cut off the alarm. Triple temperature protection system; over-temperature heat medium such as water protection system: Built boiler PT100 temperature sensor time monitoring the temperature of the water medium, the medium is stopped when the water temperature exceeds the set temperature of the combustor; Protection exchanger water temperature: by detecting the heat exchanger outlet temperature, controlling start and stop of the burner to protect the safety operation of the boiler, reducing fuel consumption; secondary overheat protection: overheat protection when the system is not working, the second over protection system operating in time and cut off the power boiler; a digital pressure switch: the original Japanese inlet digital pressure switch, change of the degree of vacuum in the boiler can be readily detected; when the pressure is too high, the combustion is stopped; explosion-proof valve automatic security alarm: the boiler when the internal pressure becomes slightly positive pressure explosion-proof safety valve alarm starts automatically cut off power boilers; emission automatic safety explosion-proof valve: when the boiler pressure is increasing, because EHV explosion-proof valve is broken, releasing the pressure in the boiler, to ensure safe operation of the boiler; flow switch protection; automatically detect traffic tail heating surface, ensure that sufficient cooling tail heating surface; frost protection system; burner flame failure Alarm; burner motor overload, fault protection. Key Technology vacuum leak condensing boiler embodiment is that long-term stability the degree of vacuum, the leak rate is small. Some data suggest that, if the boiler contains non-condensable gases such as air, even if the gas is weak, will have a very detrimental effect on the condensation heat transfer process. For example, air containing 1% by mass of the steam heat transfer coefficient can be reduced by 60%, resulting in serious consequences. Therefore, improving the sustainability of such a degree of vacuum of the boiler through a variety of ways is an important element. Henan fast boiler series vacuum condensing boiler is detected by a helium leak detectors, to ensure the long-term maintenance of the vacuum boiler! Vacuum automatic maintaining means introduced into the vacuum boiler operation, the interior portion of the vacuum boiler, but because of the following reasons, non-condensable gas in the boiler as the boiler operation is gradually increased. First: furnace leakage: weld seal, a slight leakage of steel. Second, no condensable gas (not prevent): water and heat medium furnace (steel plate) to release the non-condensable gases (H2 of), directly affects the degree of vacuum in the boiler. However, a chemical reaction while forming a protective film (ferric hydroxide) in the steel sheet surface, as a barrier to chemical reaction. Based on experience, the chemical reaction stops after the boiler operation two years. When the vacuum boiler non-condensable gases, the pressure will be increased, i.e., the degree of vacuum damage. Effect of non-condensable gases to the vacuum boiler heat transfer efficiency is very serious. When the non-condensable gas volume fraction of 0.2%, 20% thermal efficiency, the water temperature can not be increased, reducing the boiler output. Therefore, the non-condensable gas must be drawn vacuum boiler running.

Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial steam hot water vacuum boiler price as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).

When electrically heated vacuum phase transition hot water vacuum boiler price operation, the internal environment is a vacuum state. At this time, the intermediate medium oxygen in water will be discharged to the outside electric boilers vacuum phase transition, and therefore does not cause oxidation corrosion in the boiler, cause damage to the device. Meanwhile, vacuum hot water boiler heating heat exchanger portion of the material used is stainless steel, corrosion will not occur. Further, the electric vacuum hot water boiler only once was added a small amount of the heat medium water, increase nor decrease is running, the internal no scaling. Second, the fuel (gas / coal) vacuum phase transition boiler

The comparison of hot water vacuum boiler price failure rate: 1, vacuum degree of vacuum boiler in vacuum boiler * important index of stable operation of furnace, and four main factors that often affect vacuum degree: 1) whether there is leakage point in boiler body and valve, instrument, and so on. At present, including imported valves and meters can not ensure that there is no leakage within 3 years. 2) it is inevitable that failure of control part, boiler controller and negative pressure, pressure controller will also happen in operation, for example, the failure rate of domestic controller is even higher. 3) vacuum pump, three-way solenoid valve is working normally or not. As a result of the vacuum pump, the three-way solenoid valve is not operating very often and is originally installed Mouth also easy to appear the card dead and in the operation occurs the fault. 4) the load can not change abruptly, the boiler load change is very normal for the boiler, generally, the boiler can meet the load regulation of 30% ~ 100%. The above faults will cause the change of the vacuum degree of the boiler. At this time, the gas tightness of the boiler, whether the control part is normal or not, the vacuum pump, the three-way solenoid valve are normal or not, and the change of load should be checked. If all normal should be checked negative pressure and pressure controller settings, all normal vacuum recovery boiler can still be normal, otherwise the boiler should be shut down and overhauled all-round inspection. The failure maintenance rate of vacuum boiler in actual operation is higher than that of existing boiler. Pressure steam boiler, control requirements are higher than steam boiler. 2. The normal pressure boiler only has the basic time, temperature, water level control, hot water boiler controller selected the original inlet, the failure rate is relatively low. There is no need to maintain vacuum control equipment, without complex control equipment, personnel operation requirements are simpler than vacuum boilers, the probability of downtime maintenance is less, the actual operation of hot water boiler is much more stable. The comparison of boiler safety: 1. If the vacuum degree of the vacuum boiler is not guaranteed due to the above four factors, it may cause the boiler pressure to rise rapidly, and the boiler body is a closed structure, and the operator may cause the boiler pressure to rise rapidly. If paralyzed, it is possible to become the danger of pressured steam boiler, the vacuum operation of vacuum boiler is more safe based on the premise that the vacuum degree of boiler can not appear problem. 2. The atmospheric hot water boiler of atmospheric pressure boiler is as simple as boiling water, and no fault will cause boiler pressure. The boiler www.boilermanufactory.com is more safe and reliable, and it is really free of any danger.
