As early as abroad in the 1970s had developed exhaust gas temperature is 40 ~ 50 ℃ condensing gas 4 ton boiler plant russia. The so-called condensing gas boiler is to use a condensing heat exchanger in the exhaust gas boiler steam condenses down, in order to achieve improved thermal efficiency boiler, gas boiler to reduce pollution. Since the fuel gas in the boiler used in most of the hydrocarbon, the higher the flue gas water vapor content, and is much larger than the coal-fired boilers. If the exhaust gas temperature is higher than the flue gas dew point temperature, water vapor as latent heat of the flue gas drained, it will take away a lot of heat. In North Shaanxi an example, wherein the hydrocarbon fraction accounted for 95.5% by volume, containing a large amount of hydrogen in the fuel element, the exhaust contains large amounts of steam, if the temperature is lowered to a dew point temperature of exhaust gas, the exhaust in the flue gas recovery section sensible heat and latent heat of the steam, the thermal efficiency of the boiler can be improved 1O% to 15%, a considerable number.
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam 4 ton boiler plant russia fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
Fast 4 ton boiler plant russia also has a boiler industry-leading cloud service system, users use the site each boiler are closely linked to the after-sales system, system timing boiler full range of checking and monitoring the daily operation of the boiler once the abnormal situation immediately triggers an alarm, devices and notify management personnel of the boiler, to avoid a great extent on the accident.
There are reasons for which reason the 4 ton boiler plant russia fouling boiler fouling, first calcium and magnesium contained in the water hardness or to the iron, the silicon content is too high;? The same time, since the high temperature high pressure boiler special conditions. The main scale formation process is: 1 pyrolyzed at high temperature and pressure, some of the original water-soluble calcium, magnesium salts (e.g., bicarbonate) thermal decomposition, a precipitate became soluble substance. 2. The solubility decreases at high temperature and pressure, some salts (such as calcium sulfate, silicate, etc.) the solubility of the substance is greatly reduced with increasing temperature, up to a certain extent, will a precipitate. 3. pot of water evaporation, is concentrated under heat and pressure, the concentration of the salt in water with the substance and concentrated by evaporation pot and increasing, when reached saturation, precipitate separates out heating surface. 4. Conversion to react with each other and the original larger solubility in water, salts and other salts react with each other in operation, the generated precipitate insoluble material. If the reaction occurs at the heated surface, is formed directly on the scale; if the reaction occurs in water to the pot, slag is formed. Some of the water is a viscous residue, and when the sewage is not timely removed, will be converted into scales. Additionally, some corrosion products adhered to the heating surface, are often easily transformed into a metal oxide scale. These substances precipitate bond boiler heating surface to form a scale, the higher temperature portion, the more easy to form a hard scale.
