Capstone Issued U.S. Patent for New Fuel Injector to Meet Strict Tier 4 Emissions

CHATSWORTH, Calif., Oct. 10, 2016 (GLOBE NEWSWIRE) -- Capstone Turbine Corporation ( (Nasdaq:CPST), the world's leading clean technology manufacturer of microturbine energy systems, announced today the issuance of U.S. Patent No. 9,366,432 for a new, cleaner fuel injector apparatus, raising the company’s patent portfolio to 127 issued patents comprised of 100 U.S. and 27 international patents, expiring between 2016 and 2035.

When used with liquid fuel, Capstone’s multi-staged lean pre-vaporizing, pre-mixing fuel injector provides ultra-low emissions that meet United States Environmental Protection Agency (EPA) Tier 4 requirements for power generation. Preheated combustion air from the microturbine’s recuperator is utilized by the fuel injector to finely vaporize liquid fuel, and the multistage design optimizes the fuel/air mixture for a cleaner burn.

Over the years the EPA has adopted multiple tiers of emission standards. Most recently, they adopted a comprehensive national program to significantly reduce emissions from off-road diesel engines used in construction, industrial and power generation applications. Under this new program, exhaust emissions from these engines will be required to decrease by more than 90 percent.

“Capstone’s product development group is doing an excellent job moving the technology forward in meeting continuously lower global emissions standards without the crutch of using emissions aftertreatment devices, which increase the first cost and the total system complexity and inherently lower reliability,” said Darren Jamison, Capstone's President and Chief Executive Officer. “Interest in liquid fuel versions of our product are increasing as more remote applications and markets that do not have the benefit of low-cost natural gas are looking to become more environmentally conscious without sacrificing reliability,” added Mr. Jamison.

The patent is currently available for Capstone’s C65 microturbine product but will soon be extended to other products in the company’s extensive line. Furthermore, the fuel injector system is reverse compatible with older units and can be easily integrated in the field with the addition of new updated software.

“We are excited to further reduce our product emissions to meet EPA Tier 4 requirements when burning liquid fuel,” said Tony Lorentz, Director of Product Development at Capstone. “This additional achievement of our combustion and fuel development team is broadening the worldwide application of our product. The team’s focus is now on the application of butane, ethane, syngas and high H2S fuels,” added Mr. Lorentz.
