Qiaqia food as essential goods along with leisure time, loved by the people, it can be said to be suitable for all ages. March 2, 2011 Qiaqia food (stock code 002557) listed on the Shenzhen Stock Exchange. Today, once a small workshop into a modern enterprise, committed to spread happiness Qiaqia food taste is king of roasted China, the products are not only popular in the country from the seeds to grow a little, but also exported to Asia, Europe and the United States more than 30 countries and regions, has become the world understand China snack food culture an important window.
Characteristics of hot water boiler described in Henan fast boiler gas hot water boiler with water in vacuo characteristics having different boiling points at different pressures working environment. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler -0.07Mpa working in a pressure range of the water boiling temperature is lower than the corresponding 93 deg.] C, vacuum gas hot water boiler of the boiler to work under pressure. Combustion temperature of the water rises to the boiling temperature of the boiling water produced the same surface temperature steam, which absorb large amounts of heat volatilization. In this case, the water injected into the boiler heat exchanger, the cold water in the steam tube is an outer tube is heated into hot water then flows, steam is condensed out of the cold water cooled tube heat exchanger into water droplets. This completes the process water circulation in vacuo. 1. In the flue tube mounting closed fins increase the heat transfer effect, so that more concentrated arrangement. 2. Integral with a square configuration, personalized spraying, separation shape appearance. 3, large furnaces can techniques: effective to increase the heat radiation per unit area, to reduce NOX emissions. 4. Pure ensure high boiler water boiler water scaling, oxidation. Fives. All wet back shell using tricyclic structure, static heating, large heat balance. 6, all active control system, no staff on duty. Simple pulse level detection circuit unique structure, reliable performance. 8. Out of the water temperature display is doubled, easy to control operation of 1400kw ultra-low nox condensing vacuum hot water boiler and crumb. 9. High quality multilayer centrifugal glass wool insulation, heat losses are small. Vacuum hot water boiler with three gas-pressure safety protection system: automatic safety explosion relief valve: When the pressure inside the boiler continues to rise, the explosion-proof valve due to excessive pressure and burst, releasing the pressure inside the boiler, to ensure the safe operation of the boiler; a digital pressure switch : imported from Japan digital pressure switches, ready disassembly. Detecting the degree of vacuum changes the boiler, when the pressure is too high, the end of fire; explosion-proof valve automatic safety alarm: In special cases, when the pressure in the boiler becomes slightly positive pressure explosion-proof safety valve controlled vibration alarm, turn off the power boiler.
Vacuum hot water boiler fuel gas vaporized to produce vaporized overtemperature problems reasons 1400kw ultra-low nox condensing vacuum hot water boiler fuel gas, there are two major surfaces, one is vaporized over temperature, there is a is a partial vaporization, the causes leading to also have different, corresponding solutions are different. If the fuel gas vacuum hot water boiler heating system and hot water circulation loop gravity, it must be open gravity circulation valve. Because once the system failure caused by constant pressure boiler pressure device or system to reduce leakage, the position will not be caused by pressure vaporization system. After this case should an emergency shutdown immediately, and quickly identify the reasons, causing the system pressure to be reduced to exclude faults, the need to make the system running for some time in the cold state, until constant pressure returned to normal in order to determine the role of put into operation again. The local boiler vaporization problems are likely because of poor internal fuel gas vacuum hot water boiler water circulation conditions, the presence of water stagnation zone, tube angle is too small, the water velocity is too low and so on; there may be a forced circulation boiler (back the introduction of improper water distribution pipe layout, flow maldistribution caused when the fuel gas vacuum hot water boiler occur more serious pot of water vapor, combustion equipment should be stopped, but the circulating pump should continue to run at the same time open the occurrence of vaporization backwater valve circuit, to increase the flow of water. when the water hammer tube disappears before gradually returning operation of the combustion equipment.
Analysis of how the production side if the vacuum boiler formal professional formal professional vacuum producers able to provide professional boiler to the public, targeted one-design, and can provide a more professional and authoritative vacuum boiler system plan to the public, can guarantee exact best standards in the industry, may have the most cost-effective high-performance, make sure you buy other financial burden does not exist, and the characteristics and safety of use, it can get the best authority standards.
