low NOx vacuum boiler for heating in hotel

Why vacuum hot water low nox vacuum boiler for heating in hotel does not explode? 1. What is vacuum boiler?-Called vacuum inside the boiler means during normal operation of the boiler in the boiler pressure below atmospheric pressure, and cold water from the cold water with heating thermally transform. II. Why not vacuum hot water boiler explosion? 1. Due to the operating state of the vacuum is a vacuum hot water boiler, instead of a pressure vessel, a certain amount of heat medium water seal in the furnace body, any state will not dry air burning . 2 is equipped with destructive devices: explosion-proof valve.

Shanxi Province is located in China's western areas north of the Loess Plateau, the terrain finished solid, rich products. Thanks to energy supply and price advantage of coal, coke, metallurgy, electric power and other coal industry, the rapid rise of the formation of Shanxi coal-based economies of resource-based industries.

Shanxi Province, but had coal and Xing, but also because of the coal and sleepy. According to the report, "2017, Shanxi Province, coal accounted for the proportion of energy consumption up to 84.6%, higher than the national average of 24 percent, it is 2.9 times as much as the global average of Shanxi to 1.6% of the national land area, consuming about 10% of national coal amount. for Shanxi, winning the battle of blue sky, coal pollution can be effectively controlled is the key.

According to the "Blue Sky Battle Shanxi three-year action plan," issued in July this year (hereinafter referred to as "" Shanxi three-year action plan '') planning requirements, by 2020, sulfur dioxide, total nitrogen oxide emissions are lower than in 2015 more than 20%, compared to strive average concentration of sulfur dioxide in 2015 fell about 50%. Among them, 2020, total coal consumption in 8 cities in key areas to achieve negative growth, the province's coal consumption in primary energy consumption share dropped to 80%, the proportion of the province's coal consumption of coal accounts for more than 55%.

According to Shanxi Province Bureau of Statistics latest data, as of the end of August this year, Shanxi Province, the outgoing power 50.67 billion kwh, up 21.1%; the first half of Shanxi new energy consumptive power grid to complete 15.6 billion kilowatts, an increase of 58.2%, new energy abandoned consumption fell 90.6% year on year, abandoned electricity rate fell 10.2 percentage points.

The past two years the province shut down 52 coal mines, quit production capacity 45.9 million tons, subtract coal production capacity of 9.25 million tons per year, the completion of energy-saving 18 million kilowatts of coal-fired power plants, coal-fired power plants province's average coal consumption of electricity of 320 grams per kilowatt-hour of standard coal. In the first half of this year, the province's above-scale industrial Shanxi coal industrial added value increased only 0.8%.

Vacuum hot water low nox vacuum boiler for heating in hotel fuel gas vaporized to produce vaporized overtemperature problems reasons 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.

What are the advantages of using vacuum low nox vacuum boiler for heating in hotel? Vacuum boiler is primarily a device for modern intelligent residential heating, are usually provided with heating and sanitary hot water heating in places such as commercial establishments and residential areas, the traditional use of heating equipment compared with high security performance so there is no danger of explosion, cracking and expansion so easy to hurt people's appearance. So, good quality vacuum boiler which has the advantages of using it? First, the vacuum boiler mainly take the form of a vacuum suction operation, whereby in use, excellent safety and case rupture boiler explosion does not occur, while the force of the vacuum boiler steel high pressure zone and high temperature zone to achieve successful separation, using when the boiler due to the action of the vacuum can be prevented damage to the equipment where high temperature and pressure occur and can extend the life of the device functions. Second, the overall configuration of the vacuum boiler design more scientific and rational, having a smaller overall footprint advantage whereby in use can greatly save area, and to implement vacuum boiler pan vivo heat exchange can effectively shorten the warm-up period, and reduce energy waste. Third, the vacuum boiler to take automatic intelligent control mode, can be realized when using unattended or remote intelligent network control can be used to manipulate the device, and the inside of the vacuum stainless steel boiler provided with a heat exchanger, so that no rust phenomenon and not pollute the water. Fourth, the vacuum boiler cf mainly take the form of indirect heating boiler, external heat exchanger and circulating water pump in the overall installation cost can save a large part, and the vacuum boiler also has a fast heating, heat transfer efficiency and good thereby saving features high fuel costs. Above is the advantage of using a good quality vacuum boiler has, for the cold winter season in terms of the need to provide heating or region, the choice of the best vacuum boiler used in a variety of different places use homes, schools and shopping malls, etc., not only to facilitate people to use heating and also has a strong safety.
