Abstract

This study aims to design, construct and test the waste heat recovery by closed-loop oscillating heat pipe with check valve from pottery kilns for energy thrift, were used the working fluids with a filling ratio of 50%. The (CLOHO/CV) was made of copper capillary tube with inside diameter of 2.03 mm. The lengths of evaporator and condenser section were 20 cm. The lengths of adiabatic section 10 cm. The number of turn was 40 meandering turns. The ratio of number of check valves was 0.04. The evaporator section was heated by hot gas, while the condenser section was cooled by fresh air. From the experiment, it indicated that the working fluid changes form water to R123, the heat transfer rate increased to 4,800 and 7,900 Watts and the effectiveness increased from 0.32 to 0.44. The CLOHP/CV heat exchanger can reduce the quantity of using gas in pottery kilns and achieve energy thrift.
