Abstract: PURPOSE:To positively prevent the counter-flow of smoke from a combustor to the inlet port side of a biaxial screw feeder, make it possible for substance such as powder/grains to be transported by small force, and prevent the substance from being excessively compressed inside a transfer cylinder to be jammed even when blowout of fluid is stopped. CONSTITUTION:An opening 14 is provided at the lower part of a blocking plate 11 for blocking up a discharge opening 2 of a biaxial screw feeder, and the front end part of a transfer cylinder 15 is connected to the opening 14 part. Fluid is injected from an injection nozzle 17c provided on the lower side of the opening 14 toward the rear in the feed direction to blow off material bodies.

Abstract: PROBLEM TO BE SOLVED: To improve heat transfer efficiency by suppressing pipe resistance in an expert at which no trouble occurs during practical use. SOLUTION: A turbulence element 1 is securely supported on the inside of an inner pipe 7 of which a double pipe type heat-exchanger is comprised. The turbulence element 1 comprises a pair of guide plates 2 and 2. The widths of a pair of guide surface parts 5 and 5 of which each guide plate 2 is composed is increased toward a downstream side. A distance between a pair of the guide surface parts 5 and 5 is increased from an upper stream portion toward a downstream portion. This constitution forms first and second flow spaces 9, 9, 10, 10, 9a, 9a, 10a and 10a between an inner peripheral surface 7a of an inner pipe 7 and the turbulence element 1. Further, the phases, throughout the peripheral direction of the section of the inner pipe 7, of the pair of the guide plates 2 and 2 are made different from each other.
