Description
The small CoPilot module (approximately 6" square, and 8' long) is easily positioned within virtually any section of a flue gas duct. A catalyst sample is inserted within the module. An eductor, operating off of plant compressed air or steam, draws the flue gas through the catalyst. An injection grid is positioned before the catalyst, to provide ammonia, or any other liquid or gaseous additive, into the flue gas flowing through the module. A heater can be provided at the-inlet end, to give even greater versatility to testing parameters. A soot blower is also positioned at the inlet for cleaning the catalyst. Integrated sensors and probes for T, delta P, V, NOx, and NH3 are provided as standards. Other sensors and probes are available.
Installation and Operation is a Snap
The CoPilot is shipped with mounting hardware, or a gas-tight door, depending upon the intended use. Normally, the catalyst sample can be inspected, changed, or serviced, without an outage. The CoPilot is designed for simplicity, with no moving parts, and is precalibrated prior to shipment. A modular data reduction software is included. The program is customized to the specific application, so that the CoPilot package will arrive, ready to work, with the customers specific interface and optimization requirements.
Versatility
For NOx applications, the CoPilot will: predict catalyst performance (NOx reduction and/or ammonia destruction for existing, as well as anticipated, duct and catalyst configurations); evaluate catalyst wear and substrate pluggage; permit side by side comparative testing; provide valuable data for the effect of boiler modification on SCR/SNCR; aid in the study of the impact of SCR/SNCR on the balance of the plant, verify warranty performance; investigate catalyst poisoning situations, ascertain velocity limitations; obtain "early" answers by increasing flow through the test module; tune control parameters for SNCR and SCR interplay; and the like.
The CoPilot is not limited to catalyst evaluations, for example the CoPilot can also be used to investigate: the cause of air preheater element pluggage (substitute sample pack of heater elements instead of catalyst modules); soot blower or acoustic cleaning cycle parameters; and, with the addition of a nominally priced accessory to the basic CoPilot package, observe adsorption/desorption/regeneration efficiency.

Where to position CoPilot
CoPilot can be positioned in any number of locations, depending upon the use and data required, for example, at areas: |
"A" - for high temperatre applications
"B" - the normal insertion area for SRC applications
"C" - when investigating potential pluggage of air preheater elements
"D" - for low temperature catalyst, or for adsorption/description applications
Typical Users
A/E firms, fossil fuel burning energy producers, catalyst manufacturers, providers of SCR and SNCR equipment or services, and companies involved in VOC control.
