electrical hot water boiler stainless steel water pot
Corrosion causes and methods boiler boiler corrosion is often used in the home or small-scale industries, there will be worn at the time of its use or corrosion is inevitable, but this phenomenon is caused by loss of equipment will give, I give below describes the reasons of corrosion and methods of its corroded: common corrosion forms superheater tubes and reheater, high-temperature furnace: a, a gas side corrosion, corrosion gray matter. 2, anti-corrosion method: controlling the temperature of the furnace tube, the melting point of the condensate is skipped, deferred control the oxygen content and surface treatment selected tube control, reduce the combustion of sulfur produced. 3, dew point corrosion: SO2 gas generated by the combustion, the flue gas in combination with comfortable, and sulfuric acid produced in the condensation and corrosion of the metal in the metal surface below the dew point. 4, stress corrosion: refers to brittle cracking occurs under tensile stress while the action of the metal in the particular corrosive medium and a certain level. Second, the water-side corrosion comprising: 1, corrosion free carbon dioxide: hydrogen water acidic substance depolarization caused by corrosion. Corrosion Methods: water equipment to try to remove the CO2 and carbohydrates. 2, under deposit corrosion: the metal surface when you boiler slag or scale adhesion, severe corrosion can occur beneath it, referred to precipitate corrosion. Corrosion Method: The pH of the water in the apparatus is maintained at between 9 and 11, the metal surface of the boiler protection film is stable, does not corrode. 3, soda corrosion: the metal corrosion is a chemical vapor oxidation of iron occurs. The method of anti-corrosion: Depression evaporating section smaller inclination angle, ensure the normal circulation, for higher superheat temperature superheater, heat should be used, good corrosion resistance and the like of steel pipe. 4, DO corrosion: In the soda system, metal corrosion of the steel is prone to corrosion by dissolved oxygen. Corrosion: Water favor oxygen, increase the flow rate of water, to avoid the accumulation of oxygen in the respective area, so that uniform contact of oxygen with the metal wall to form a more uniform corrosion. Boiler is very special operating environment, temperature and pressure and corrosive substances can cause equipment corrosion conditions occur, for which we have to take the right precautions to avoid future corrosion occurs during use.
Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast boiler R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
Chemical plant flue gas boiler house design parameters required chemical plant flue gas boiler house design parameters required for the design of the boiler room when the chemical plant for flue design is also a requirement, if the design does not meet the specifications, then the words of the late , but also will cause great trouble. So, for chemical plants, it must be easy to overlook these places also to pay attention to it. Otherwise, if the latter then rework it, the loss will be greater. 1. The flue should be straight, air tightness, attachment and less and less resistance, horizontal flue persist for more than 1% of the laying head should be positioned to avoid Longitudinal placement. 2. Fuel gas-fired boiler house and chimney flue should be used to build a steel or reinforced concrete, the lowest point of the flue and chimney should be set lump water-sealed water drains. 3. The thickness of the metal plate is generally used in flue 4 ~ 6mm, flue planning, equipment should meet the reinforcing ribs to ensure the strength and stiffness requirements. 4. The thermal expansion of the flue should be compensated, and the compensation amount should be accounted for proper selection. The insulation should be of steel flue ways and reliable fixation. 6. The fuel gas boiler corresponds to a boiler should be a chimney, when subject to the conditions required several constraints when sharing a boiler flue or chimney, each boiler should be ventilated suction force balance. 7. The flue should be arranged to set the necessary thermal and environmental measurement points measurement points in the right orientation. Additional single evaporation equal to 20t / h or a single additional fuel boiler thermal power of 14MW or greater, it is necessary to monitor successive fixed soot, SO2 concentration in flue gas discharge apparatus. 8. In the simple collection of local and smoke when many boilers a share or a total chimney flue shall be fitted with explosion-proof door on the flue after each fuel gas-fired boiler, the orientation of the vent should be conducive to relief, shall be located in the proper orientation before and do not endanger the safety of the turn, when the gas blast may endanger the safety of the operator is full, the guide tube should be installed on the pressure relief explosion-proof equipment. 9. For some longer flue boiler room, they should be accounted for resistance, select the appropriate blower, Fan (when there is draft fan), in order to ensure clear smoke. 10. The chimney should be considered appropriate preservation approach, the chimneys of flue gas temperature should be above the dew point of the flue gas temperature of 15 deg.] C; when the exhaust gas temperature is lower than the dew point temperature of flue gas, the flue gas should take effective measures to avoid the intrusion.
What is the role of atmospheric gas hot water boiler shutters and works? Shutters gas hot water boiler, generally speaking, only on pressure hot water boiler. It is only a valve, commonly called the system we open and close valves. For opening and closing the valve in terms of pressure hot water boiler is to prevent reverse flow of water into the boiler system, within a certain time, the system will overflow from the boiler water, boiler room drowned. Before, in the absence of this device, mainly rely on manual, but the manual, there will always be this way or that kind of operational errors, and this is the reason why equipment shutters. In addition, for boiler water back down phenomenon, Xiao Bian would like to add a little common sense, if the boiler water rewind, treatment is not timely, it is easy to create enough internal pressure is too large, the worst case, such as boiler boiler burst accident, will follow and, causing unnecessary damage to property staff.
