Abstract:

As a result of investigations of efficient designs of heating surfaces for heat regenerators of gas turbine plants a new sheet was developed for heating surfaces of heat exchangers constituted of corrugated sheets with fine-grained bulges. The results of experimental investigations and juxtaposition of various heating surfaces according to their heat yield showed the high efficiency of heating surfaces constituted of corrugated sheets with fine-grained bulges. Banks of pipe elements constituted of sheets with a new profile, have a greater strength owing to seam welding along their entire length. The tests covered a range of Re values from 4,000 to 15,000. Thus, the range of Re values corresponding to the actual operation of heat regenerators of gas turbine plants was covered by the tests. The formulas for the determination of optimal flow velocities and their ratios, developed according to the devised procedure and on the basis of experimental data from the investigation of the new heating surface, ensure its best utilization for the operation of heat regenerators of gas turbine plants.
