Corrosion causes and methods ce approved high quality pellet 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.

When steam is generated between the vertical wall surface of the steam ce approved high quality pellet boiler temperature difference exists in the vertical steam boiler and the steam boost heating process, the bubble exists between the temperature difference and the temperature difference along the thickness of the vertical wall, the inner wall temperature above the temperature of the outer wall, the upper wall surface when the temperature is above the lower case, to prevent excessive thermal stress, must be slow step of the vertical steam boiler. Vertical steam boiler during ignition and during the boosting, the vertical steam parameters of the steam boiler, the water level and the operating conditions of each component is constantly changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, be sure to arrange professional staff to closely monitor changes in a variety of vertical steam boiler meter indication. Since the water temperature in the steam boiler vertical rising bubbles and an evaporator heating surface of the metal wall temperature began to rise at any time, need to pay attention to thermal expansion and the temperature of thermal stress, because the wall thickness of the bubbles is relatively thick, vertical steam boiler the main problem in the heating process is a thermal stress. At the same time, but also consider the overall thermal expansion problems, especially for a vertical tube steam boiler heating surface, because the thin wall thickness, length of problems in the heating process is a thermal expansion of the whole, but also pay attention to thermal stresses, prevent neglect caused the failure.

Difference pressure hot water ce approved high quality pellet boiler and pressure hot water boiler (1) boiler pressure hot water boiler heating system is pressure equipment, with a risk of explosion. The boiler pressure hot water boiler heating system is not under pressure, always open to the atmosphere so that the boiler will not explode in any case, good safety performance. (2) pressure hot water boiler is full of water, there is no level control problem. Pressure hot water boiler 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) pressure hot water boiler to be fitted with a pressure gauge, safety valve and thermometer, because the boiler always is full of water, so no water level, water level gauge and thermometer and only pressure hot water boiler, boiler and air because the same, the pot is always pressure to atmospheric pressure, there is no risk of explosion, do not have to install the safety valve, pressure gauge may not be installed. Circulating pump (4) pressure hot water boiler heating system is sent to the return pumping systems engineering boiler, water pump is generally used. 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. The boiler circulating pump water heating system pressure 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. (5) Supply of low pressure hot water boiler not only water, but also for high-temperature water. Pressure hot water boiler can supply the low-temperature water of less than 100 ℃
