Crematoria
Mercury Abatement must be fitted to half of all crematoria by
31st December 2012. Current equipment involves high levels of
expenditure, and may not be suitable for smaller crematoria.
Strict emissions limits also apply to Carbon Monoxide, Dioxins
and Furans.
Crystal-Air’s™
utilises patented technology to eliminate flue emissions and
incorporates 99.9% efficient Mercury Abatement. The system
offers a smaller footprint than most other products on the
market and can be fitted to existing cremators with no modifications.

The
Crystal-Air™ system is a 5 Stage Thermal Oxidizer using
Combined Staging being a series of external combustion
chambers of varying sizes and lengths that significantly reduce
emissions. It has its own on board auxiliary combustion system
which can use any type of liquid or gaseous fuel.
How
it does it
There are three chambers or cells.
 |
The
first chamber is called the 'Mixing Chamber'.
Inside this chamber, the gases rotate longitudinally;
something like a tornado would look like. This rotational
effect causes the combusting gases to reside or dwell
longer in the chamber.
The
second chamber or cell, is called the 'Combustion
Chamber' where the majority of the heat is produced,
this is the centre chamber. As the combusting gases
enter this chamber there is sufficient oxygen for continual
and intense combustion. As the gases reach the exit
end of the combustion chamber the oxygen content in
the chamber has been significantly deplete.
The
third chamber or 'Reaction Chamber' is where
the oxygen depleted gases enter and chemical reactions
take place. Upon reaching this chamber the gases are
now starved for oxygen because most of the available
oxygen has already been depleted from combusting all
carbon and hydrocarbons in the previous chamber.

What
makes it work?
The
gases working their way through start in the 'mixing chamber'
where air and fuel are mixed and ignited using the onboard
auxiliary burner unit. The gases then move into the 'combustion
chamber' where total combustion takes place. The temperature
in this chamber is the hottest of all of the chambers. Final
chemical reaction takes place in the 'reaction chamber'
and the gases are exhausted out of the end of the chamber.
The cooled gases pass through the mercury abatement system
which uses activated carbon as its medium, removing 99.9%
of mercury oxide.
Final
filtration uses the latest downward flow cartridge system
and advanced pulse cleaning technology before release to atmosphere
through the stack.
Heat
from the system can be recaptured and used for building services
or even power generation.
