Spiral heat exchanger e.g. high pressure pre-heater, for use in power plant, has cylindrical container, and radially inner and outer heat exchanger coils comprising different spiral radius and same tubular length
摘要
<p>The heat exchanger has a cylindrical container (12) with a coolant supply (14), and a coolant return that is displaced in an axial direction. The coolant supply and the coolant return are connected with each other by a radially inner heat exchanger coil (16) and a radially outer heat exchanger coil (18). The heat exchanger coils comprise different spiral radius (32, 34) and same tubular length.</p>
