Vacuum hot water papermaking hot water vacuum boiler dealer hot water boiler parameter is a heat exchanger to transfer heat to the hot water through evaporation and condensation heat of boiling heat transfer medium. It consists of a condenser and an evaporator heat exchanger. The evaporator heat exchanger having a combustion chamber and a boiler convection heating surface. The heat released by combustion of the fuel the heated surface of the heat medium water generated saturated steam under corresponding pressure. Condensing vapor rises in the heat exchanger to the cold leg, condensation latent heat of vaporization. The heat is transferred to the hot water supply heat exchanger, and the water heated to a certain temperature, and then sent to the heat user. After cooling, the condensed water is returned to the evaporator vaporizes, thereby continuing to provide heat to the outside. Vacuum hot water boiler is working characteristics using water at different pressures and boiling temperature. At atmospheric pressure (0.1MPa), at 0.06MPa pressure, the boiling temperature of water is 100 deg.] C, the boiling temperature of water is 85 ℃. Phase change heat transfer vacuum hot water boiler operating pressure range of 2.67 kPa to 66.6 kPa. Corresponding saturation temperature is 15 ~ 85 ℃, vacuum at the operating pressure of the boiler, the combustion temperature of the heat medium water saturation temperature to rise, and the steam generated in the water at the same temperature. Then the cold water in the outer tube is heated in the steam tube. Sending user of hot water, the steam condenses into water droplets of the outer tube, and then heating the back surface, completing the cycle. It features two vacuum hot water boiler: The results are as follows: (1) low intermediate medium temperature, exhaust gas temperature is low, greatly improving the thermal efficiency. (2) If the medium is lower than the saturation temperature at atmospheric pressure, even if the medium is broken, it will not cause an explosion soda. Fuel (gas) vacuum boiler parameter table we have a design team specializing in the production of vacuum hot water boiler, advanced testing equipment, international standard factory buildings, decades of industry experience serving more than 10,000 users, Henan fast Boiler Vacuum Hot Water boiler is trustworthy!

Water quality vacuum hot water papermaking hot water vacuum boiler dealer is what vacuum hot water boiler quality requirements: a body of water to be a softening of the heat medium, late life without supplements. Conventional boiler water quality standards and in fact the same, particularly, a vacuum hot water boiler water quality requirements are the following criteria: 1, the furnace as a heat medium water in the furnace, the whole process is not out of the boiler operation, the increase or decrease, It closed only in a vacuum chamber of the boiler, heat transfer between the heat transfer tubes and the boiler heat exchanger. 2, the cooling water circulating device from high temperatures, less demanding quality of the circulating water. 3, the heat medium furnace needs completely deoxygenated pure water. The only way to avoid the furnace corrosion and scaling. Thus, the boiler water quality is the key, be sure to choose water quality standards, so the life of the boiler over 20 years, or even longer. High speed side vacuum heat produced by the hot water boiler efficiency, non-polluting cleaning operation, in line with low nitrogen emissions requirements. long lasting. Welcome to inquire.

It is reported that Shandong Province to further promote the action of atmospheric pollutants governance, but also to "defend the blue sky strategy" escalating, the Shandong provincial government amended the new "Regional Air Pollutant Emission Standards" and other three local standards, as the province's mandatory local standards of environmental protection, on November 1, 2019 formally implemented.

1, to improve the standard index-related emissions, can improve the level of clean production, reduce pollutant emissions, Forced out of high-emission equipment, improve air quality. The revised standard canceled the densely populated high-polluting industries sewage privilege, the use of emissions phased strategy partition; divides a region of Shandong Province as the core focus, and general control zone, different regions perform different emission limits, based on the location of the enterprise partitioning control requirements.

2, a new round of defense blue sky "Strategy" will be ultra-low emissions standards covering all coal-fired boilers in Shandong Province, and will gradually promote the non-coal industry, requires iron and steel, coking industry emissions to meet ultra-low emission standards. Key building materials industry emissions control area cement, ceramics, lime, glass, etc. are also required to achieve ultra-low emission standards, the general control zone cement, ceramics, glass and other building materials industry emission requirements more stringent than the national standards.

3, changes in air pollutant emission standards in the current round of revisions is the biggest "air pollutant emission standards iron and steel industry." The new revised standard will help eliminate a number of small-scale, backward technology, compliance governance hopeless small-scale iron and steel enterprises, and guide the existing steel enterprises discharge standards by clean energy alternatives, etc., so as to promote Shandong Province, energy, industrial restructuring, improve the quality of atmospheric environment.

4, according to monitoring data, 2018, Shandong fine particulate matter (of PM2.5), particulate matter (of PM10), sulfur dioxide (SO2), (NO2) average concentration of nitrogen dioxide fell 14.0%, 8.5%, 33.3 %, 2.7%; the number of days of heavy pollution fell for 5 days. Wherein the fine particulate matter (of PM2.5) than the average concentration of 2013, 2015 decreased 50.0%, 35.5%.

According to the "2013 Shandong Province - 2020 air pollution control plan" in 2020, the province's basic ambient air quality standards, compared with 2010 improved by 50%. Since 2013, Shandong "broken wrist" environmental pollution, has released various standard 102.

Vacuum hot water papermaking hot water vacuum boiler dealer in use, what convenient place?

Vacuum hot water boiler is mainly used in shopping malls, hotels, schools, residential housing, entertainment venues and other officers to concentrate on providing sanitary hot water and heating. A negative pressure inside the boiler, and the outside atmospheric pressure is low, compared with the conventional heating device, having high safety, no explosion, expansion cracking and other dangerous situations. So, good quality vacuum hot water boiler which has the advantage of using it?
