Development and Commercialization of an Integrated Commercial Cooking System with Ultra High Efficiency

摘要

This report discusses the initial steps in the development of an integrated commercial cooking system that uses a deep fat fryer with a pulse combustion burner/heat exchanger as the basic unit. Waste heat from the fryer will then be used in other appliances to achieve as high an efficiency as possible. The first step of the program was to verify that a pulse burner could in fact be used in a deep fat fryer without having excessive surface temperatures to deteriorate the oil. A number of burner/heat exchanger designs adaptable to single-vat fryers were then constructed and evaluated. The most recent design has over 4.6 square feet of heat transfer surface area and a boiling water efficiency in excess of 76 percent. The initial work on burner designs adaptable to split-vat fryers has been accomplished. The development of secondary appliances was initiated by studying the heat losses in both insulated and non-insulated pipes using a pulse combustion burner with operating characteristics similar to the single-vat burner as the heat source.
