A written Guarantee of 10% Bunker fuel savings.
That’s exactly what Green Framework is offering with the NG1 Cyclonic Exhaust system. The NG1
system has been shown to deliver 15-18% savings over millions of hours in real
world use on both rail and road transport.
Supercomputer design work on the gas flow through the
exhaust system has allowed very precise placement of spiral fins inside core of
the NG1 unit. CFD (Computational Fluid Dynamics) have been devised such that
the gas is spun as it passes the fins. This gas in accelerated and a pumping
cyclone develops which draws the gas away from the engine much faster than it
would normally flow, allowing turbo chargers to spool up and admit more air for
better combustion.
Now ship scale units are available through a partnership
between the NG1 TechFlow and Green Framework. Units to handle engines as large
as 18 Mw are available. Large units are already being fitted to marine engines
in power production and auxiliary roles.
“To have a guarantee of performance is a very comforting
thing”, says Tomas Rodriges “But also to have a drop in the CO2 and other
emissions ahead of whatever is coming in the form of regulation can’t but help
too”.
Green Framework CEO Barbara Dutton-Weingarten points out
that the NG1 system is almost maintenance free and can be tuned to peak
performance in about an hour. “The great thing about these units is that they
are on and working hard as soon as the engine is running, you don’t need to be
at sea or up to speed unlike hull coatings, ducts, fins or Boss caps for
instance, they just save fuel from the get go”
A 10% fuel saving is nothing to be sneezed at when the shipping
industry is scraping around trying to get 2% or 3% from efficiency hardware. With
less than a year to recoup the cost of installation in most cases and short
installation time the NG1 from Green Framework is likely to be a big hit with
the continually squeezed owners and charterers alike.
