Aerovalved Pulse-Combustion Systems for High-Efficiency Commercial/Industrial Boilers

摘要

Pulse-combustion systems, in commercial/industrial (C/I) boiler applications, offer the potential benefits of increased efficiency and reliability. Aerovalved pulse-combustion (P/C) systems have no moving parts, pump their own combustion air, and generate an overall pressure rise through the burner system. These features should lead to more compact boilers requiring less maintenance. Aerovalved P/C technology has been developed in this program to permit P/C modules to operate on low pressure natural gas. Two modules were successfully coupled to operate in opposed phase. A laboratory demonstration boiler with 6 P/C modules was designed, fabricated, and tested with various module combinations. Results indicated that a more fundamental understanding of pulse combustion burners is required before practical commercial/industrial systems can be developed.
