Multi-Disc Rotary Generator (MDRG)
The MDRG-MK6-NGT is a turbocharged Brayton-cycle turbine generator. It burns raw wellhead methane continuously to spin a direct-drive permanent-magnet generator that puts out 75 kWe of 480 V three-phase power. An optional thermal module recovers heat to produce midgrade steam.
01
Fuel and Intake
Your gas enters at wellhead pressure, dewetted but otherwise untreated. Intake air is filtered through the front housing air cleaner insert.
02
Compression and Boost
A turbocharger compresses inlet air pressure ahead of the combustor to feed the combustion and system processes.
03
Continuous Combustion
Fuel and boosted air burn continuously in an annular combustor. The cycle absorbs variable gas composition and intermittent flow instead of stalling on them.
04
Expansion and Durability
Hot gas expands through our novel disc rotor assembly creating rotation and torque. Carry‑over moisture and particulate pass straight through.
05
Generation & Exhaust
A permanent-magnet generator runs on a common shaft. Output is conditioned to 480 V three-phase, and an optional thermal module recovers the exhaust heat for midgrade steam generation.
