The Research & Development Department conducts research testing of
Coen products at its Woodland, California facility, currently under development.
Additional performance testing can also be performed at field locations
as necessary. Coen’s combustion test facility is over 10,000 square feet
in size and includes five furnaces, each designed and constructed to simulate
a different combustion application. Each furnace is instrumented to allow
all data to be logged by a data acquisition system. Combustion air can
be supplied to all furnaces with an indirect-fired air heater capable
of raising the air temperature to 500°F. A flue gas recirculation system
is installed in several of the furnaces to aid in low NOx emission burner
development.

Package Boiler Simulator
This test facility is 8 feet in diameter and 40 feet long. It has
the capability of firing both gas and oil, and both FGR and pre-heated
air (up to 500°F) can be supplied. The boiler simulator has been
fully instrumented to provide in-situ emissions and temperature measurements. |
 |
Up-Fired Test Facility
This smaller furnace has rectangular internal dimensions of 4-feet
wide by 4-feet deep by 12-feet tall. The facility can fire gaseous
fuels, and has been instrumented to make highly accurate in-situ measurements
of temperature and emissions. |
 |
Firetube Boiler Simulator
This test facility has the capability of firing either gas or oil
fuels, with the option for FGR. It is 31 inches in diameter and 167
inches long, and has been instrumented to measure emissions and temperature
in-situ.

Duct Burner Test Facility
This facility allows firing duct burner prototypes in the controlled
environment identical to actual applications. It includes a 900
hp firetube boiler, dilution air fan, flue gas recirculation and
water injection systems that together generate simulated turbine
exhaust gas (TEG) with wide range of variables such as mass flow,
oxygen and moisture contents and temperature. In addition, the NOx
level in simulated TEG can be varied from 2.5 to 25 ppm (corr. to
15% O2). The duct burner part of the facility is a 30 ft long furnace
lined with fiber refractory. The furnace expands in cross section
from 3.5 x 4 feet to 3.5 x 7.5 feet resembling a scaled down typical
duct between a gas turbine and waist heat boiler. The facility is
equipped with state of the art instrumentation, controls and burner
management system.

External Test Facility
This un-enclosed test stand can be used in some cases for testing
gas or oil-fired pilots and other small burners. Because of the visibility
it provides, it is the “employee’s favorite”. |
 |
Fan and
Register Air Flow Test Facility
This test stand is an actual Coen windbox and fan assembly, which
is used to provide highly accurate air flow conditions. This includes
both the windbox as well as burner registers. It is also used for
quality testing of certain fan wheels. |
 |
Firetube Boiler
This
boiler is a part of the duct burner test facility but can be also used for the purpose of testing new burners and combustion controls. State of the art combustion controls and instrumentation enable testing of the dynamic response and accuracy of different control schemes. |
