Wet back Low Pressure Boiler
The depth of integration with the Internet industry, the party has been fast out of traditional industries inherent in the old ideology, gradually moving towards intelligent high-tech enterprise development. Chinese Good Technology, a leading research. With the continuous improvement of the Group's own pursuit of quick side with Tsinghua University, Xi'an Jiaotong University and Zhengzhou University entered into a collaboration, research cooperation agreement signed, and the establishment of upgrade Engineering Research Center - Laboratory cleaning wet back low pressure boilers, combustion field exploration and try. This year, the group also reached with Hefei General Machinery Research Institute Xuedong academician cooperation, the establishment of "academician workstation", as the industry's cutting-edge technology research and innovation base. Confirmed eyes, fast boiler is rare good business.
Fang fast production of electric wet back low pressure boiler furnace using a reliable water separation design, better security; also features multi-level, a number of protective measures water temperature, secondary overheating, over-temperature, leakage, antifreeze, and other power anomalies, which frost protection Fang is fast unique patented technology, comprehensive protection of the safe operation of electric boilers.
Natural circulation type is SZS series another feature. Both WNS steam wet back low pressure boiler and SZS steam boiler has three pass design to ensure fuel effectively burning.
Flue gas waste heat recovery system based on heat absorption: the absorption heat exchanger concept will be applied to flue gas heat recovery wet back low pressure boiler of the gas, the process shown in Figure 1. In additional gas absorption heat pump with the boiler flue gas condensation heat exchanger, an absorption heat pump with natural gas as a drive power source, to generate cold medium, the cooling medium in the flue gas in the flue gas condensing heat exchanger, heat transfer process can be direct contact heat exchanger or an indirect heat exchanger, the exhaust gas temperature of the system dropped below the dew point, condensation of water vapor in the flue gas heat, flue gas heat recovery purposes and moisture. Backwater into the heating network is first heated by the absorption heat pump and then into a gas boiler after heating to a temperature designed to give out, completion of the heating process water heating network. Exhaust gas boiler into the bottom of the chimney, the draft fan is placed on top of flue gas condensation heat exchanger is withdrawn after mixing with the exhaust fumes into the absorption heat pump condensing heat exchanger, the exhaust system temperature is reduced to 30 ℃ vented to the atmosphere into the chimney after less. Out of the chimney flue gas between flue gas and returned to port additional partitions. Our experimental system using a direct contact heat exchanger flue gas condensation. With this technique enables efficient heating system (system for use with a low ratio of heat input into the system of a gas heat) increased by more than l0%. Currently the technology has been applied in Beijing GLD waste heat recovery boiler room engineering, Beijing bamboo plant waste heat recovery boiler project, achieved good energy saving effect. This incremental investment techniques (including absorption heat pump investment, flue gas condensation heat exchanger and related pumps, valves and other equipment) can be recovered usually within 3a.
