CEMS Functions

SpectraView was designed specifically for CEMS data acquisition, management, and reporting by experts with over 12 years of experience in the CEMS industry. It provides a logical and economical approach to the management of CEMS information and incorporates functions to simplify the CEMS operator’s tasks.

Special displays and summaries notify the operator of CEMS alarm conditions and emission exceedances. Reason codes and corrective action data can be entered and stored for each exceedance. Daily calibration error tests are summarized and reported, including alarms and flags for out-of control conditions as defined by the EPA. A missing data substitution routine enables strict conformance to 40 CFR 75 specifications. SpectraView was one of the first Part 75 data acquisition systems to achieve EPA verification.

Audit logs track the date and time of all CEMS functions and operator activities. Maintenance activities can be recorded in audit logs or on customized maintenance screens. Trending graphs and lists enable clear display of real-time and historical data. A RATA (Relative Accuracy Test Audit) routine simplifies data collection during CEMS testing.

The SpectraView report library includes all reports required by 40 CFR 75 and 40 CFR 60, including hourly and daily reports, excess emission summaries, and quarterly reports. Reports can be viewed on line, printed to hard copy, disk or tape, and transmitted electronically to regulatory agencies. Custom reports are easily developed for state and local agency requirements or customer needs.

SpectraView can also satisfy the needs of gas and oil-fired plants that use the Part 75 Appendix D and E options to calculate emissions. The necessary parametric data, such as oil flow rate, sulfur content, operating load, and heat input, is efficiently collected, calculated and reported. A virtually unlimited range of data manipulation is possible, including statistical analyses and predictive modeling.

SpectraView Architecture

Almost any system configuration is possible with SpectraView. A typical system includes a SpectraView terminal, located in the CEMS building, that interfaces with Spectrum Systems’ Data Acquisition System (DAS) programmable logic controllers (PLCs), or other dedicated controllers. The DAS, PLC, or controller serves as the front-end data collection device that receives signals directly from the CEMS and other equipment. The SpectraView terminal provides an operator interface, display, and reporting capabilities.

Each SpectraView terminal can be linked to a plant and/or corporate computer that collects, stores, displays, and reports data form one or more locations. SpectraView is flexible enough and powerful enough to allow you to build almost any kind of network you need to make data available wherever and whenever it is needed. SpectraView supports an impressive range of platforms, tools, networks, and data base structures so that it can seamlessly interface with any company network structure.

The capability of SpectraView to rollup data from multiple sites enables a whole range of management possibilities from centralized maintenance dispatching and coordination of CEMS quality assurance testing to development of cost modeling data for fuels versus emissions.

Phone modem communications enable our engineers to troubleshoot your system or provide software updates without the time or expense of an on-site service call in most cases.

Program Structure

Because SpectraView is a UNIX-based system, it provides multi-user, multi-tasking capabilities and real time data handling. The system continuously collects and stores data in the correct units of standard while simultaneously providing and operator interface, printing reports, writing data to disk or tape, or performing other system functions.

SpectraView uses a logical data dictionary file structure and a standard Graphical User Interface that enables efficient data integration and export of data to industry standard applications such as dBase, Lotus, Excel, Auto-Sketch, and others. Once stored in SpectraView, data is easily examined, sorted, and manipulated.

On-line functions and displays are presented in an intuitive and uniform Windows format. SpectraView satisfies the needs of novice users and experts alike.

New data points, alarm set-point modifications, special report formatting and other operational revisions are made without changing program code using SpectraView’s straightforward configuration tools.

Spectrum Systems CEMS

SpectraView is an integral part of Spectrum Systems’ complete line of CEMS and is also available as a stand-alone or retrofit system. Spectrum’s Model 300 Dilution Monitoring Systems provide reliable monitoring of SO₂, NO_x, CO₂, volumetric flow, and other parameters to meet EPA requirements. Combined with Model 300, SpectraView sets the standard for CEMS data acquisition in a wide range of applications, including coal and oil-fired boilers, waste incinerators, hazardous waste and hospital incinerators, pulp and paper plants, cement plants, petrochemical plants, gas turbines, and co-generation facilities.

The SpectraView stand-alone version can be used to interface with your existing CEMS. The retrofit version upgrades your data acquisition capabilities with the reliability and power of SpectraView and can even use your existing PCs in many cases.

Spectrum Systems, Inc. is built on a foundation of expert service and quality. Each spectraview system includes Spectrum’s complete support from documentation and training to on-site and factory service. Our technical assistance center is staffed around the clock, 365 days per year to provide customer assistance. Because we’ve been providing CEMS service for over 15 years, we have the knowledge and experience to deliver the support you need.

Parametric Monitoring

When it comes to parametric monitoring, almost every supplier will tell you they can do it. Spectrum Systems’ engineers can tell you they’ve done it.

Using the powerful and versatile SpectraView™ program, Spectrum has designed and installed parametric monitoring systems that are working now to satisfy 40 CFR 75, Appendix D, Appendix E, and Appendix G requirements.

Using the defined protocols, plus fuel data, process parameters, and unit efficiency data, SpectraView enables qualified facilities such as oil and gas-fired utilities, combustion turbines, peaking units, co-generation facilities, and others to take advantage of less costly emission monitoring. It can be used to satisfy the requirements for parametric emission monitoring, alternative monitoring, and predictive emission monitoring systems.

Our data acquisition and handling systems have demonstrated reliability, accuracy, and timeliness in parametric monitoring applications.

Within a sophisticated, yet user-friendly framework, SpectraView provides:

• Real-time collection of parametric data
• SO₂ emission data calculations using mass flow or volumetric flow
• NO_x emission data calculations based on electrical output, heat input, unit efficiency, and fuel factors
• CO₂ emission data calculations using 40 CFR 75, Appendix G specifications
• Easy-to-use entry screens for fuel analysis data
• Hourly, quarterly, and annual data averaging
• Quarterly electronic reporting in compliance with EPA specifications
• Data display and editing functions
• Efficiency plots and graphic displays
• Provisions for missing data substitution in accordance with EPA specifications
• Scheduling and configuration displays

SpectraView provides true multi-tasking, multi-user operation, plus flexible networking configurations.
