Ecom introduces stationary engine emissions analyzer

Designed for stationary engine applications such as generator or compressor sets and boilers, Ecom America Ltd. has introduced a wall-mounted emissions monitoring and reporting system designed for unattended operation.

The new Ecom stationary engine emissions analyzer (SEEA) is designed to measure [O.sub.2], CO and N[O.sub.x] in the exhaust gas of up to four diesel or natural gas engines, as well as gas turbines or boilers at preset intervals.

Besides the standard system, SEEA is also available in a low N[O.sub.x] version capable of measuring single-digit N[O.sub.x] applications with 0.1 ppm resolution, said Drew Wilson, president of Ecom, Gainesville, Ga.

"The SEEA provides operators of stationary engine installations with a recognized means of automatically monitoring and recording the exhaust emissions of their engines," Wilson said.

The SEEA system is built around the Ecom A Plus analyzer, which has been tested under EPA's ETV verification program. Operators can program the system to periodically sample each of the four exhaust ports and temporarily store the emissions data in a spreadsheet until it can be downloaded to a host PC. The data can be retrieved via USB link, dial-up, or it can be automatically sent, via email, to a designated e-mail address The analyzer's NEMA 12 housing is designed to be mounted in a climate-controlled space in close proximity to the engines being monitored. The 0.25 in. sample lines are routed from each engine exhaust system to sample connections located on the top of the analyzer housing. The system is powered by 120 Vac 60 Hz and measures 20 in. x 20 in. x 10 in.

The test sequence begins with the SEEA turning on and initializing, and then selecting the first engine exhaust port. A sample of gas is drawn over a user-defined time and frequency. The SEEA then automatically switches over to the rest of the engine ports, repeating the sequence.

All of the data, Ecom said, is time stamped, and includes engine identification and location information for review and analysis. The system then goes into standby mode until the next measurement cycle. Specific measurement and cycle times are user programmable.

The system is designed for unattended operation and requires minimal periodic maintenance and calibration, Ecom said, with the calibration generally determined by the installation's specific operating permit.

The system has an alert lamp to provide visual identification of filter change or fault, and alerts are also available as part of the reports for remote notification of engine or analyzer problems
