摘　　要：基于Solidworks三维软件开发研制的燃气锅炉直接接触式节能器及其性能测试系统,可对节能器进行全面的热工性能测试。测试证明,选择适当的运行参数,节能器能够有效地回收烟气的显热和潜热,能使150℃～250℃排烟温度降低到40℃左右,生产70℃左右的热水,显著提高燃气锅炉的能源利用率。On the basis of 3D software Solidworks, the direct-contact gas-fired boiler economizer and its performance testing system are developed and put to use the comprehensive thermal performance testing of the economizer. Test proved, the economizer can effectively recover flue gas sensible heat and latent heat as long as the appropriate operating parameters,can drop the flue gas temperature of the range between 150°C-250 °C to 40 °C and produce hot water temperatures of 70 °C or so,and the overall energy utilization efficiency of the gas-fired boiler can be significantly improved.
