    초록 We develop heat exchanger modules for a multi-burner boiler. The heat exchanger module is kind of a heat recovery steam generator (HRSG). This heat recovery system has 4 heat exchanger modules. The 1st module consists of 27 bare tubes due to high temperature exhaust gas and the others consist
    of 27 finned tubes. The maximum steam pressure of each module is 10bar and tested steam pressure is 4 bar. In order to test these heat exchanger modules, we make a 0.5t/h flue tube boiler (LNG, 40 Nm3/h).
    The test results of 100% boiler load show that heat transfer rate of 1st module is 49.7Mcal/h which is 34% of total heat transfer rate and that of 2nd module is 82.6Mcal/h which is 57% of total heat transfer rate. The 3rd and 4th module has 10.2Mcal/h(7.0%) and 3.5Mcal/h(2.4%). The reason of
    higher the heat transfer rate of 2nd module than that of 1st module is that the 2nd heat exchanger module has finned tubes instead of bare tube. Especially the heat transfer rate of 1st finned tube of 2nd heat exchanger module is 56.5Mcal/h (39% of total heat transfer rate). From this result, it is very important of optimum design of the first finned tube among all water tubes.
