HEAT RECOVERY SYSTEM

摘要

Objective: Successfully installing a Heat Recovery System for Starch Processing Applications Method: The cooking of starch is a staple element of the paper making process, irrespective of the kind of starch applied. In this step, the starch is heated under pressure and by direct steam. This is followed by relaxation in a cyclone, whereby the resulting expansion steam and heat energy contained therein is oozing unused into the atmosphere. By storing the starch, the patented GAW Heat Recovery System makes use of the heat energy that escapes during the cooking of starch. GAW technologies have developed a compact modular system that recovers the energy through a heat exchanger. The energy of the suspension is fed back in at the inlet to the Jet Cooker, thus reducing the amount of direct steam. Findings: The heat recovery system at starch preparation lines is well established in the market, enabling energy savings of over 50% for the inactivation of the Jet Cooker. This modular system helps to protect the environment and substantially lowers costs. GAW heat transfer equipment enables customers to recover maximum heat energy while still providing high thermal efficiency - with low installation, operating and maintenance costs.
