| Condensing steam condenser is the main equipment of thermal power generating units. Condenser in the operation of the unit operation not only affects the economy, will affect the unit safe and stable operation. 200MW thermal power generating units due to the current arrangement of the condenser tube bundle is unreasonable, causing the heat transfer efficiency is not high, affecting the economic performance of the entire unit. Condenser for transformation, to improve economy and reliability with the advantages of contributing to energy saving.Be modified to enhance its effect of heat transfer condenser, vacuum needed to improve the work unit. But the old power plant with many problems facing the same choice of transformation is the first issue to be decided. Use reasonable piping mode, and select corrosion resistance and high resistance to structural capacity TP316 stainless steel pipe rehabilitation programs. Reform programs and related studies.The results show that, BD + stainless steel piping mode matching method, from the point of heat transfer, mechanical and corrosion resistance point of view has a good effect, has a certain value. |
