PowerGen

PowerGen by Qnergy delivers more power than TEGs or fuel cells, and is priced much lower per Watt.

What will you with the extra Watts and BTU's efficient design delivers?

We provide power solutions to anyone requiring critical remote power solutions in response to AEP (Alberta Environment and Parks) regulations to create offsets usable under CCIR (Carbon Competitiveness Incentive Regulation) for advanced environmental compliance. Our energy efficient PowerGen series helps producers comply with costly California Energy Commission-administered LCFS (Low Carbon Fuel Standard) in advance of Canadian implementation. Highlights of the PowerGen system:
  1. Reliable even when fuel quality is poor or contains H2S.
  2. Low maintenance (1-2 hr/year is typical) (air filter, glycol maintenance mostly)
  3. Long lifespan (80,000+ hr design life, and units are now running 13 years continuously at NASA labs)
  4. Reduce venting, flaring
  5. No grid power contract or install wait, can be moved.
  6. lower cost/Watt (2-10x less vs. TEGs)
  7. Hail and theft/vandalism resistant and more reliable vs. solar
  8. Scalable (plug and play)
  9. Meaningful power = meaningful solutions (5- 7.5 HP/PowerGen)
  10. Well-suited to 4+ well pads or truck-out/LACT unit power
The generator package works seamlessly with a variety of fuel supplies, including natural gas, propane, ethane, biogas, and multiple associated gas streams. An available 5,650 Watts means you still have power left over to allow for AC heat trace in colder climates with an additional controllable glycol system heat supply of 48,000-60,00 BTU/hr. PowerGen supplies flexible power and BTU's.

FAQ's

Q: What happens internally if the air intake was to suck in an air/gas mixture? A: Powergen is tuned to operate lean- access fuel of around 3.5-4% O2. Adding fuel into the intake air will in turn reduce the oxygen content, causing a rise in the flame temperature until it becomes too rich, causing incomplete combustion and high levels of carbon monoxide. The Powergen monitors its engine head temperature and will lower the burner rate when the head over-heats. Therefore there is no risk to the hardware. In all cases the flame remains inside the combustion chamber and is not capable of traveling upstream beyond the quenching plate (perforated plate behind the burner deck). Burner chamber volume is sized so that the flame cannot exit and travel down the sealed exhaust ducting, therefore no exposed flame. Supporting illustration:   Q: Can this generator as a whole ignite external flammable gases? In other words, should you treat the PowerGen as open flame equipment, which impact its location on the site due to spacing requirements of this type of equipment? Answer: The Qnergy PowerGen 5650 has an enclosed combustion chamber that is fully encapsulated within heat exchangers in such a way that there is no exposed heated surface hot enough that could cause pre-ignition to external air-borne flammable natural gas. In terms of ingress of external air-borne gas via the exhaust system into the combustion chamber, we have a positive pressure combustion chamber which, when the unit is operating, prevents any ‘unintended’ flammable gas access to the combustion chamber. To help you with locating the PowerGen on your site, we have further clarification from Alberta's Energy Regulator: "Given how the Sterling engine operates, with an enclosed combustion chamber and no possible way for a flame front to exit the unit if an air/gas mixture is drawn in, I conclude that it operates more like an internal combustion engine rather than flame type equipment." (June 25, 2018) Q: The PowerGen is capable of burning sour fuel gas with up to 1,000 ppm H2S; Will we be required to do dispersion modelling? Answer: Section 7.12(1) of (Alberta Energy Regulator) AER Directive 060 requires dispersion modelling if the H2S content is greater than or equal to 10 mol/kmol (your 1000 ppm would be 1 mol/kmol) or one tonne per day.  PowerGen doesn’t trigger either of these, so dispersion modelling would not be required by Directive 060. Note that our free-standing height is only 54 inches, so it would be possible for the emissions to be very undispersed if someone was standing nearby. OilPro recommends consideration is given to determine whether the operator might want some sort of setback distance so that a person couldn’t stand too close to the exhaust. The heat of the exhaust will provide some lift and may act like an effective stack height, taking the plume up into the air, to then disperse more as it travels downwind. The Air Quality Objective for SO2 is 172 ppb, so the dispersion would need to be taken from the original concentration of about 1,000,000 ppb (1,000 ppm) resulting from the original 1,000 ppm of H2S, down to 172 ppb.  Dispersion is quite effective, so this is probably not difficult to achieve (comparatively much larger sources still dilute to levels below 172 ppb), but if required it is recommended to model the scenario to be sure of each case. Bottom line: no, AER requirements do not require a model of the gas stream of this low H2S concentration and rate.

Background

About Sterling Engine Technology:

The original kinematic Stirling machine, developed over 200 years ago by Rev. Robert Stirling, did not attain significant technical or commercial success until the latter half of the 20th century. An increased focus on this technology over the last 50 years has led to significant recent breakthroughs in terms of operating concepts and supporting technologies. The principal “Stirling advantage” is that it is a closed-cycle external combustion engine, meaning the heat source is outside the engine and the inside of the engine can be sealed. Stirling engines also make use of a regenerative heat exchanger that allows them to re-use their heat. This regeneration feature is what makes the Stirling cycle efficient, in addition to allowing it at the same time to be powered by virtually any heat source (e.g., oil, gas, solar, wood, coal, nuclear, and other combustible material)
