Vacuum hot water boilers and pressure hot water boiler specifically what is the difference Today, many are unified district heating boiler combustion modes of supply of hot water, hot water boiler performance and therefore plays an increasingly important user of heating role. The most common on the market are vacuum hot water boiler and boiler atmospheric hot water boiler. However, many consumers these two hot water boilers may not have a deep understanding. First, security is now different professional vacuum hot water boiler hot water boiler main purpose of the internal trigger negative pressure hot water boiler can achieve rapid, constant temperature, but also by the vacuum hot water boiler pressure hot water boiler structural changes related So special and safe. However, good pressure hot water boiler hot water boiler in use only local ventilation, it is particularly safe and reliable pressure hot water boiler. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, the need for multiple cycles of heating burners, boilers, hot water boiler pressure vessel can be opened with just one burner, in order to achieve a good heating effect. It can effectively heat the water circulating in the hot water boiler, and the heat efficiency of the hot water boiler higher than atmospheric vacuum hot water boiler. Third, the complexity of the equipment in order to ensure different vacuum, vacuum hot water boiler must be installed infrastructure series a vacuum pump, but the average hot water boiler pressure control device need not be employed to maintain the vacuum. Therefore, in the absence of complex control device, the operation more simple, the complexity of the boiler equipment is also to meet the needs when more users.
Gas boiler manufacturers to remind you to pay attention to maintenance is usually everyone talking about gas boilers actually contains a lot of classification, we used gas boilers mainly includes the following types: WNS-type gas-fired boiler, SZS type gas boilers, gas power plant boilers, coke oven gas, blast furnace gas recovery boiler, vacuum gas hot water boiler five, gas boiler how to maintain it through the summary we conclude that:? 1, need to pay attention during the operation (1) prohibits pressurized combustion furnace or smoke, because this is very easy to burn plus hole cover (2) on the bottom ground plane is not water, to prevent wet etching 2, gas boilers have every one month to check again. 3, after running for six months should stop using and check with the reports in a comprehensive inspection once before, damaged parts repaired or replaced. Check main methods: (1) The main part of the weld inspection or inspection under pressure the inner wall or outer wall of the furnace no corrosion. If you find corrosion should immediately stop using, if you find some very small scratches or other marks, should be recorded and promptly repair (2) should be checked after completion of a paint brush to prevent corrosion of the gas is above three points again common maintenance of the boiler, the advantage is to make your life growth boilers, and efficiency is not reduced. Maintenance of not commonly divided into two are a dry method and a wet maintenance regimen. Shutdown of the time difference between the two is the length of time
Recently, we learned: Rugao City, Jiangsu Province Supervisor Bureau Jiang Security Bureau adhere to safety first, prevention first, the principle of comprehensive management of energy saving, in-depth implementation of boiler production, sale, use, import and other aspects of business within the jurisdiction of the main energy saving responsibility inherent jurisdiction to conduct a hazard investigation work boiler.
Inspection process, City Supervisor Bureau Jiang branch of law enforcement personnel to go to boiler units, key to see whether there are coal-fired boilers, boiler inspection whether, whether for the use of registration, whether special equipment operator certificates, boiler safety management system developed and the status of implementation, boiler employees education and training, and emergency rescue drills to conduct audits, establish inspection records and ledger work, to maximize the elimination of security risks.
Up to now, there were still not found the use of coal-fired boiler of Unit within the jurisdiction. City Supervisor Bureau Jiang Security Bureau will continue to work closely with the various departments work together to advance environmental protection and ecological civilization construction work to further strengthen supervision to achieve a comprehensive cleared coal-fired boilers.
Food plant causes corrosion and the effects after stopping the boiler factors: food factory after disabling boiler corrosion causes and influencing factors after food factory boiler shutdown, with decreasing pressure and temperature inside the boiler steam condenses into water, boiler a vacuum inside, the outside air leaks into the furnace, the oxygen and water vapor in the vapor state. Metal is prone to corrosion. Boiler structure, if you do not take some measures to stop the use of corrosion is inevitable. For example, can not be discharged superheater superheater water. When the internal heating surface has a water-soluble metal salt scale, when it absorbs water, will form a high concentration solution of salt, which will aggravate the etching stopper, internal corrosion is formed ulceration. Often this is the entrance to the superheater. Because the separated saturated steam upon entering the superheater boiler always carry a small amount of water, the saturated vapor absorption heat upon entering the superheater, the boiler water is evaporated into steam, boiler water salt deposited on the inner wall of the superheater. Heater inlet pipe.
