Use of waste heat to preheat energy saving 10t boiler plant feed water gas wind energy-saving technologies as China's emphasis on environmental protection, the application proportion of gas-fired boilers to increase year by year. Up to now, the total size of the gas boiler has reached the ownership of 12% of the boiler to reduce the exhaust gas temperature of the boiler has been an important research direction in the field of energy-saving gas boiler. Using a flue gas waste heat boiler feed water preheating gas to the wind energy technology significantly recovered waste heat in the flue gas, the boiler can decrease by the original exhaust gas temperature 120 ℃ to 40 ℃, boiler efficiency can be improved by 4% -11%. Meanwhile, application of this technology can also reduce the nitrogen oxide emissions, energy saving and environmental double benefit. 1. The principle of the technical content art technique and the two-stage flue gas condensate recovery heat exchanger technology, greatly reducing the exhaust gas temperature of the gas boiler, the flue gas waste heat to achieve recycling. First, a heat exchanger device, the flue gas temperature is reduced to below 60 ℃, recovering the sensible heat of the flue gas; secondly, the use of air preheater is cooled at room temperature, the flue gas will be reduced to below 40 ℃, recycled flue gas sensible heat and latent heat; Finally, the slightly acidic pure condensed water as supplementary heating system processing, and the third stage heat recovery. Meanwhile, the technology also has an exhaust gas recirculation system, by changing the combustion boiler, to suppress generation of nitrogen oxides. 2. Key Technology (1) High-performance heat exchanger assembly design and processing technology. The stainless steel plate punched into projections, grooves; projecting between the two plates opposite the top groove, as a supporting point; bottom of the groove is relatively narrow flow channel configuration.
Henan run Q & Gas Boilers (b) 1. Internal gas energy saving 10t boiler plant drum Henan mainly those devices and how they effect the arrangement position A:?? Henan gas boilers with capacities of different parameters, it is not exactly the drum inside the device - like, now at high pressure and ultra-high pressure boilers drum example, describes internal devices, their arrangement and a major role. Along the length of the drum is mounted at both sides of a plurality of cyclones, each cyclone barrel top is arranged a louver (wave plate) separators, their primary role is to rise by the tube into a mixture of soda and water vapor will be the initial separation. In the upper steam drum, steam cleaning horizontal mounting plate, on which the cleaning water supply layer, when the steam passes through the water layer, put dissolved or carried vapor partial turn salt was dissolved in water, to reduce the steam salt. Near the top of the drum is provided with a perforated plate, a uniform flow in the ascending vapor drum, and the water vapor is further separated. About 150mm with the drum center line of the discharge pipe opening accident; continuous blowdown piping is provided at approximately 200mm port under normal water line, and then disposed below the dosing tube. Also installed at the entrance of the downcomer cross blade. To prevent a drop generating swirling nozzle causing drop tube bucket with steam. 2. Continuous outfall mouth Henan gas boilers are generally installed where? Why? How much sewage rate? A: Top nozzle Henan continuous gas boiler 200 is generally mounted on a drum at the lower 300mm normal water level (i.e., "0"). Since the pot of water evaporation continuously gradually concentrated in the vicinity of the surface of the water with the highest salt concentrations. Therefore, continuous blowdown piping port Henan gas boiler should be installed in the region of the maximum boiler water concentration to high concentration continuously withdrawing boiler water, supplemented with clean water supply, thereby improving the quality of boiler water. Henan gas boiler blowdown rate is generally about 1% of the amount of evaporation. 3. What pot of water treatment dosing in Henan gas boiler drum sense Answer: the pot to prevent the fouling, if simply to remove the water contained in the outer boiler feed water hardness, needed more equipment will greatly increase investment; and plus? cauldron blowdown, heat loss not only increase the working medium, can not be eliminated pot residue water hardness. Thus, in addition to using external boiler water treatment, but also on the water in the boiler pan dosing process, remove the pot residue water hardness, to prevent boiler scaling. The method of addition of phosphate which is in the pot of water, so that calcium and magnesium ions and phosphate ions bound water pot, Rong generating hard water precipitation sludge, sewage regularly excluded, so to maintain a certain boiler water phosphate, neither fouling and corrosion, but also to ensure the quality of steam. 4. What Henan gas boiler regularly sewage outfall aim is installed in the mouth where A:?? Because Henan pot of water gas boilers containing rust and dosing process water precipitated the formation of slag and other impurities deposited on the bottom of the water circuit, regular sewage the purpose of the water is periodically discharging slag and other impurities precipitate, increasing the pan of water quality. Periodically outfall generally located in the lower header, or concentrated water wall lower portion of the downcomer.
CFB energy saving 10t boiler plant have many kinds of applications,especially used in chemical factory,power plant,cement plant and textile mill and so on.30 ton circulating fuidized bed boiler is used to being the first choice by industry enterprises.
As the only fast energy saving 10t boiler plant boiler manufacturers, we were invited to participate in this event. The conference has invited one of the advocates of Tsinghua Academy of low-carbon development executive vice president Li Zheng, Chinese Academy of Engineering, Tsinghua University, China Environmental Engineering disciplines - Jiang Yi, vice chairman of the European Society of HVAC ManuelGameiro, Many sophisticated scholars in the Beijing Institute of architectural design Co., Ltd. VENTILATING Chief Engineer, China Academy of building Science and Technology Xu Wei, chief engineer specializing in HVAC and other fields. Report of the meeting theme is clear, rich content, covering industry hot issue, aroused heated discussions delegates.
