Benz Air Engineering has engineered developed and implemented a wide range of systems that reduce emissions and increase the efficiency and operational flexibility of steam-generating and combined heat and power systems. We are the sole company that can guarantee the following on boilers.
Greater than 95% fuel-to-steam efficiency
Greater that 50 to one turndown.
NOx emissions less than 2 ppm @ 3%O2 over a 50 to one turndown.
Electrical Generation for less than 4500btu/kw-hour HHV
Electrical powered 150psig Partial Quality Steam Generating Heat Pump
BAE has Patented and implemented a boiler accessory "internal combustion boiler" that is a secondary burner to an already permitted boiler. Fueled by a slip stream of natural or bio fuel gas after the boiler shutoff valve, the boiler accessory provides between 60 and 300kilowatss of power while supplementing the host boiler with near zero NOx, stoichiometric gas while generating steam in the water jacket for deareating systems. Providing behind-the-meter grid support, the less than 4500BTU/kw-hr HHV heat rate is the highest known electric generating efficiency.
BAE has developed a simple steam generating Heat Pump that compresses partical-quality 5 to 15psig waste stream steam up to 150psig. Designed and engineered to minimize superheating during compression, BAE's Heat Pump minimizes stages necessary in complicated turbo compressors. Simple condensate injection during compression yields dry saturated steam at 150psig in just one simple compression cycle at a COP greater than 3:1.
Combining high turndown and less than 2ppm NOx with the internal combustion boiler accessory and partial quality steam heat pump, BAE's systematic approach represents the best if not only near-term solution to decarbonize hard to electrify systems.
Utilizing up to a facility's grid connection to generate steam during spring winter and fall periods of excess renewable generation, BAE's partial quality steam generating steam pump offers a far superior alternative to hydrogen production by electrifying a portion of existing hard-to-electrify boilers with renewable electricity. As the grid demand increases, the internal combustion boiler accessory provides behind the meter grid support at less than a third the grid carbon heat rate.
The integration and implementation of BAE's systems cannot be possible without the superior turndown of the host boiler, the seamless capability of ramping from as little as 2% to 100% providing customers with highest efficiency, lowest costs, all at the lowest carbon footprint possible given the host facility's electrical grid connection limitations.
BAE's systems recognize the need to reduce carbon NOW. Recognizing the current and near term limitations of electrical transmission and generating capacity, the leveraging of existing hard to electrify sources like boilers to initially decarbonize a portion with the partial quality steam heat pump while augmenting the steam generation with the lowest carbon rate electrical generation represents the best if not only solution to the renewable future.
