Secondary heat exchanger for condensing furnace |
摘要 |
A secondary heat exchanger suitable for use in a condensing furnace which is in the form of a bank of a plurality of metal tubes which are positioned in a plurality of stacked rows. The tubes are interconnected to form a continuous fluid flow path and have a uniform adherent corrosion resistant polymeric internal surface. The tubes further contain a longitudinal seam which is formed by crimping the edges of the tube together to provide for the compression of two polymer surfaces together thereby forming a seal capable of maintaining its integrity at conventional design pressures.
