Bowman’s ETC Technology
Bowman’s ETC systems comprise a turbo charger, turbo generator and power electronics unit. These components work together in order to either increase the efficiency of your genset or increase the power output.
Through recovering the exhaust gases from the turbo charger, a turbo generator produces power which is cleaned by the power electronics in order to be clean and grid quality.
How the TG works
-Waste heat energy (exhaust gas) feed through TG inlet
-The force of the exhaust gas causes the TG wheel to spin at >30k RPM, unused energy is feed back to main exhaust stack
-The TG wheel is directly coupled to High speed electrical machine (alternator)
-The alternator produces a non stable AC current, which is exported to the Power Electronic unit (PE)
The ETC system consists of a turbo generator (TG) and a power electronics (PE) unit.
ETC1000 Axial flow, horizontal axis turbo generator
-Lubrication and cooling integrated with host genset
-Built-in-bypass provision (rotor lock)
-3 turbine variants for broad applicability
How the PE works
-The AC current produced by the Alternator enters the Power electronics’ module.
-This AC input current is converted to DC before the final conversion to a 3 phase AC grid standard (50/60Hz) output.
ETC 1000 Power Electronics
-110kWe, 220A rating
-400V/50Hz or 480V/60Hz operation
-Broad grid code compliance
