Selective
Non-catalytic Reduction
The inside of the Crystal-Air™ combustion chamber burns
between 1500ºF and 2200ºF, depending on fuel and air settings.
The operation of this type of chamber is such that in the
hottest zone is in the middle of the chamber. It is hot enough
to break down all compounds that flow into this super heated
zone. The super-heated zone is caused by two or more (patented)
helical stators on the inside of the combustion chamber tube.
The
helical stators cause the gases to slow down and rotate while
passing through the combustion chamber and are therefore delayed
in what is known as 'dwell time'. The dwell time, at the operating
temperature inside the chamber, is long enough to cause total
combustion of all organic compounds. Time and temperature
both play a significant part in how much of the pollution
will be reduced. On the other side of the super heated zone
the gases are cooled sufficiently to reform again into compounds.
Water is one of the components that reforms from the combustion
gases.
The system is dynamic and can function between approximately
34% to 100% fuel input to the chambers – this is a true
variable fuel system and not an 'On-Off' operation. Crystal-Air™
is highly energy efficient in that the majority of all of
the fuel injected into the combustion chamber is consumed;
with heat and water some of the main by-products. The conversion
of fuel to heat produces the required temperatures for re-burning
the engine exhausts. Furthermore, Crystal-Air™ chambers
have no moving parts and require no maintenance.
Crystal-Air™ will be mated to the engine exhaust port
and the exhaust will be directed into the combustion chamber.
There is over 50% less NOx and CO in the exhaust stream compared
to the amounts that enter the Crystal-Air™chamber from
the engine. A further 50% reduction can be achieved using
the additional urea/ammonia dosing module.
Crystal-Air™ requires some fuel for operation which can
be the same as the fuel used by the engine. In proportion
to the amount of fuel being used by the engine, the Crystal-Air™
fuel requirements are very small.
Perhaps
Crystal-Air™ seems too good to be true. This is a real
Selective Non-catalytic reduction system that has already
been built, 'proof of concept' tested and measured, and found
to exceed expectations.
