Heat exchanger for using exhaust heat to produce steam has heat-conducting fins on boiler pipes, with projecting flow fins projecting beyond them at set spacing

摘要

The heat exchanger has heat-conducting fins (24) on the boiler pipes (20), with inner flow fins (25) and outer flow fins (26) projecting beyond them at set spacings. The inner and outer flow fins are opposite each other and offset from each other. The energy carrier (19) flows in a meandering path past the heat-conducting fins.
