Low cost CFB to power generation encouraged in the u s for bagasse

Because CFB Boiler fuel (and desulfurizing agent) is combusted repeatedly at low temperature with desulfurization reactions under the fluidized bed condition, it is a new generation of multiple-effect, low pollution, clean combustion boiler. bagasse fired boilers are commonly used to heat water and create steam for energy production. Bagasse-fired CFB boiler efficiency can often provide lower operating costs.

Poor water quality adverse effect on the industrial to power generation encouraged in the u s water quality caused by adverse negative impact on the industrial boiler caused by (1) the formation of scale. Most likely to form a variety of adverse water quality scale, this will affect the performance of industrial boilers. The reason for the formation of scale, mainly because the steam can release a lot of energy, which energy is transferred to the water, if poor water quality, the boiler heating surface will therefore have a scale, whereby the thermal conductivity will reduce the boiler, the boiler energy consumption greatly increased. The size of the thermal conductivity can be used to measure the thermal conductivity of the object, the thermal conductivity of the scale will be a lot lower than the thermal conductivity of steel, which will definitely affect the thermal conductivity of industrial boilers. (2) boiler corrosion. Poor water quality can also lead to corrosion problems boiler. Especially waterwall, economizer and other metal parts of the drum will thus deformed more weak, and even the formation of leakage, destroy the original structure, reducing the strength of the metal. In this case, the boiler corrosion problems increasingly serious about the safety of the boiler severely affected, can not function properly. Boiler heating surface there will be metal corrosion products, which is more likely to lead to more serious quality problems boiler. Under the scale, cracks, leaks and other problems emerge, a number of difficult to effectively remove debris, clogging pipes, greatly enhance the difficulty of maintenance of the boiler. In addition, during maintenance, due to difficult, it takes more time and effort, improve maintenance costs. (3) induced accidents. Due to poor water quality-induced accidents abound. According to statistics, the scale accidents caused by condensation caused by about 20%. After the accident, the device will not only suffer losses, but also cause great risk to the personal safety of staff. Therefore, to reduce accidents, improve economic efficiency, on the need to strengthen water boiler.

There are reasons for which reason the to power generation encouraged in the u s 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.

Fast to power generation encouraged in the u s was informed that Harbin City People's Government Office recently issued a "Harbin in 2019 to win the Battle of Blue Sky embodiment" (hereinafter referred to as "Notice"), referred to "notice" to implement the transformation of ultra-low emissions , with the transformation of the coal power plant conditions and the conditions of the urban built-up areas and over 65 tons of steam coal-fired boilers basically soot (particulate matter) ultra-low emission, all of the conditions of the energy saving and ultra-low emissions (particulate matter, sulfur dioxide, nitrogen oxide), substantially gas boiler low NOx combustion technologies. In particular implementation the conditions do not have emission limits, preferred embodiment of the grid or switch to clean energy. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release. Cogeneration area does not have central heating conditions, the existing multiple small coal-fired boilers, to replace the principle of construction of large-capacity coal-fired boilers in accordance with the same volume.
