Claim 14:
15. A system for forming a web comprising:
a mixing tank for holding a foamed suspension of fibers, the mixing tank in fluid communication with a water supply, a surfactant supply, and a fiber supply for receiving and combining water, a surfactant, and a fiber furnish;
a web forming process configured to receive a foamed suspension of fibers from the mixing tank for forming a web;
a recirculation loop that circulates a foamed suspension of fibers from the mixing tank and back to the mixing tank, the recirculation loop maintaining the fibers in a foamed suspension; and
a heat exchanger positioned along the recirculation loop for receiving the foamed suspension of fibers, the heat exchanger also being in fluid communication with a cooling fluid supply for receiving a cooling fluid and wherein the foamed suspension of fibers flow through the heat exchanger along a first pathway while the cooling fluid flows through the heat exchanger along a second pathway for cooling the foamed suspension of fibers.
