steam engine boilers cladded ebay
Many different types of steam engine boilers cladded ebays and pressure difference between the pressure of the boiler, where the atmospheric pressure and a lot of applications, heating effect is also very good, for which we often confuse the two, is considered to be the same kind of equipment, in the end two whether the devices are the same? Here we'll tell you about the difference between the two: 1, pressure both to supply low-temperature water, but also for high-temperature water. And atmospheric pressure can only supply low temperature water of less than 100 deg.] C. 2, the water level control problems ① pressure is full of water, there is no level control problem. ② pressure of the water level control problems. The boiler drum is full of water, still connected to the top of the box opening, there is still water level control problems. 3, is not confined to the boiler equipment ① pressure of the heating system is pressure equipment, with a risk of explosion. ② atmospheric pressure boiler heating system boiler is not always open to the atmosphere so that the boiler will not explode in any case, good safety performance. 4, elements shall be installed differences ① pressure gauge, safety valve and thermometer, because the boiler always is full of water, so no water level and water level gauge ② atmospheric pressure is only a small thermometer, because the boiler with the atmosphere, the pot pressure is always atmospheric pressure, there is no danger of explosion, it is not necessary to install a safety valve, pressure gauge can not be installed. 5, a circulating pump heating system circulation pump and pressure difference ① is pumped from the boiler, the heat pump is the pump that functions to overcome the resistance of the system, mainly to overcome the resistance of the valve regulating backwater. ② pressure of the circulating pump heating systems, pumping systems engineering is sent to the boiler return water, is generally used in water pump. It has to overcome the resistance of the systemic circulation, but also to maintain a certain pressure boilers, boiler water at high temperature to ensure that no vaporization. It can be seen atmospheric pressure, the pressure of the boiler is not the same, the main difference between the two lies in the different heating system works, so we choose to pay attention to in the future, and they need to understand is the kind of equipment, do not buy wrong can not be used.
The main steps of steam engine boilers cladded ebay pressure test: As already mentioned, the importance of water pressure test for boilers. When, a major step pressure test, pressure test under what circumstances this is there are a lot of techniques and skills.
In mid-March this year, Shenyang City, the first steam engine boilers cladded ebay industry issued emission permits. Plan will livestock poultry, dairy products manufacturing, automobile manufacturing and other industries 29 issued emission permits, issued by the maturity shall not sewage, sewage behavior of errant card companies to investigate and punish. This is also the industry's first Shenyang boiler emission permits.
According to the State Department "to control emissions permit system implementation plan" and the Ministry of Environment "discharge permit management approach", 2017 in Shenyang City has completed thermal power, paper, cement, electroplating, pharmaceutical, pesticide, textile printing and dyeing industry, 54 enterprises license issuance of work. 2018, the city completed the issuance of emission permits 128, including iron and steel industry 5, slaughtering and meat processing industry 106, 16 water treatment industry, ceramic industry one, according to industry certification and time-bound national requirements, so that " should be sent to do hair. "
This year, Shenyang City, according to "stationary sources of pollution permits Classification Catalog" requirement, will be livestock poultry, dairy products, Condiments fermentation products manufacturing, food manufacturing other convenience food, wine manufacturing, footwear, plywood manufacturing, bamboo and rattan wood furniture manufacturing, polyvinyl chloride, phosphate fertilizer, automobile manufacturing, battery manufacturing, non-metallic waste and scrap metal processing, garbage to hazardous waste sludge as fuel for thermal power generation, sewage treatment and recycling, environmental control industry , heat production and supply, electroplating facilities, sewage centralized treatment of industrial waste water and other 29 industries issuance of emission permits. Up to now, has been launched boilers, water treatment, ceramics, automobile manufacturing, battery manufacturing, phosphate fertilizer industry and electroplating processes work permits issued.
Shenyang Ecological Environment Agency, responsible person, emission permits to take "a card-style" management, so that all the laws and regulations of the environmental requirements of an enterprise integration to a convergence of the proposed permit up to implement the main responsibility for polluters. A company issuing a discharge permit, enterprises through the establishment of self-commitment, self-monitoring, accounting records and regular reporting system has proven its emissions by law, to further strengthen fine management.
Shenyang in the discharge permit issued during the EIA procedure will be incomplete, excessive emissions, there is the issue of corporate environmental management ordered rectification to achieve "issued an industry, to clean up an industry, an industry specification, an industry discharge standards." In the future, Shenyang will be implemented in accordance with the regulatory card issuing companies to carry out law enforcement inspection post card, after intensive license management, enterprise undocumented sewage discharge permits and do not follow the behavior will be investigated according to law.
Control measures Henan four gas steam engine boilers cladded ebay leaking 1, perfect wear, new technologies, new ways to increase the use of anti-corrosion measures Henan gas boiler service life. The water wall tube burner region, in particular weld position, serious high temperature corrosion, high temperature corrosion to prevent the use of new corrosion-resistant materials. 2, to strengthen the operation and management of Henan to promote over-temperature monitoring gas boiler heating surface running, to strengthen the technical analysis of the phenomenon of over-temperature. Henan gas boiler operating personnel required to correctly handle the relationship between safety and efficiency, access to information ahead of fuel, equipment, operation mode, etc., to strengthen the burning adjustment. Strictly control the heating and cooling units appear excessive speed during start and stop, hydrostatic testing and operation, over-temperature overpressure operation and combustion instability phenomenon, while strengthening quality supervision. 3, Henan reinforcing and wear proof test gas boiler inspection check baffles cover wear, wear shoe is intact and columns where the discharge tube; tube wear after checking flue gas damper temperature control device. For the water wall, in the vicinity of high temperature corrosion Wall thinning inspection combustor case; waterwall fin weld inspection, fouling and coarse diameter expansion, the temperature of the medium between the two sides of the fin tube and leave some margin expansion. In the case of the fillet weld superheater and reheater key checks the header of the nipple. 4. actively train service operator Henan excellent gas boiler maintenance operations personnel can effectively reduce the probability of occurrence of leakage of boiler plants. Therefore, the plant should actively provide scientific and reasonable training for boiler maintenance personnel to improve their technical level of maintenance and repair of Henan gas boiler, boiler maintenance and repair technology to enhance operational competence of personnel. 5. sound design appropriate to increase the margin of safety is a fundamental measure designed to "four" Crack Prevention. The arrangement of the heating surface design, the furnace hot strength steel, cross-mixing and expansion system considered reasonable, it will greatly reduce the occurrence of burst leakage.
