The purpose of this project was to develop a new CHP package that integrates a California Air Resource Board (ARB) 2007 compliant low-cost simple cycle (unrecuperated) microturbine with a ULN industrial burner. The integrated microturbine-burner assembly was to be configured into a small footprint CHP package with maximum waste heat recovery from the turbine exhaust gas (TEG) and 100 percent heat recovery from all other convective heat losses. The integrated microturbine-ULN burner CHP technology was to be applicable to industrial and commercial firetube and watertube boilers alike with firing capacities of 5 to 100 million British Thermal Units per hour (MMBtu/hr) using ULN burners. All sensible and convective waste heat from the microturbine was targeted for recovery in the boiler resulting in overall system efficiencies exceeding 80%, significantly higher than conventional recuperators used in commercial microturbine packages. The compact burner-microturbine integrated design allows for ease of retrofit to existing boilers as well as for new package boiler installations.
