This article is trying to determine the status of flue gas
\r\nthat is entering the KWH heat exchanger from combustion chamber
\r\nin order to calculate the heat transfer ratio of the heat exchanger.
\r\nCombination of measurement, calculation and computer simulation
\r\nwas used to create a useful way to approximate the heat transfer rate.
\r\nThe measurements were taken by a number of sensors that are
\r\nmounted on the experimental device and by a thermal imaging
\r\ncamera. The results of the numerical calculation are in a good
\r\ncorrespondence with the real power output of the experimental
\r\ndevice. That result shows that the research has a good direction and
\r\ncan be used to propose changes in the construction of the heat
\r\nexchanger, but still needs enhancements.<\/p>\r\n","references":"[1] M.
