Davis-Standard to Present ANTEC Paper on Efficiency of Barrel Heater-Cooler Configurations
Pawcatuck, Conn.)--Davis-Standard will present a paper entitled "Improving the Energy Efficiency of a Barrel Heater-Cooler Design for High Temperature Single Screw Extrusion Applications" at the upcoming ANTEC, May 1-5, in Boston, Massachusetts. The paper, written by John Christiano, Norton Wheeler and Jason Baird, focuses on energy efficiency of barrel heater-cooler systems.
This study examined two individual barrel heater-cooler configurations for a single screw extruder, comparing a conventional air-cooled, electrical heated (ACEH) system to a new energy efficient heater-cooler (EEACEH) system. The EEACEH system is designed to improve performance of the heater-cooler by reducing convective, conductive and radiant energy losses. An experimental barrel test unit, engineered by Davis-Standard, was used to evaluate the energy consumption of the two systems. Results showed that the new EEACEH system improved performance by eliminating the free convection of air over the service of the heater-cooler when the barrel zone required heating. It also reduced radiant energy heat loss using high performance insulation on the surface of the heater-cooler shroud. In total, the EEACEH showed a 24 to 33 percent improvement in energy efficiency over the conventional ACEH design.
