The design of high temperature flue gas heat exchanger

by:DIGUANG     2020-06-29
The design of high temperature flue gas heat exchanger 1, the overall layout. The overall layout of high temperature flue gas heat exchanger to first select the type and structure of high temperature flue gas heat exchanger, flow forms and materials, then choose the hot heat transfer surface species. To consider operating temperature and pressure, etc. 2, design index. High temperature flue gas heat exchanger design indexes including the kinds of working fluid and its flow, import and export temperature, working pressure and high temperature flue gas heat exchanger efficiency, etc. Aerospace for high temperature flue gas heat exchanger should also include the allowable pressure drop, size and quality, etc. 3, design choices. Heat exchanger in high temperature flue gas heat design and structure design is completed, provides the selection of structure scheme, then the designer according to the evaluation criterion. Consider to choose various specific conditions. Conditions for qualitative decisions, such as mold manufacturing conditions, brazing furnace size, transportation, delivery date, such as company policies and the intensity of competition will influence choice. Evaluation criterion refers to the measure can be measured, such as weight, size, shape pumping fluid cost, initial investment and life, etc. 4, thermal design. The thermal design of high temperature flue gas heat exchanger including heat transfer calculation, flow resistance calculation and determine the size. Thermal design in addition to the technical performance indicators, also need to have the heat transfer surface features, Including heat transfer characteristics and flow resistance characteristics and structural parameters) As well as fluid and thermal physical property parameters of materials.
