Prioritize maintenance to maximize your cogeneration efficiency.
Cogeneration/trigeneration efficiency allows you to save on energy costs and reduce carbon emissions. Maintenance activities are critical for ensuring continuous safety and longevity in your cogeneration facility.
By following these five steps, you can maximize the advantages provided by your facility:
Step 1 – Protect the Gas Engine with Periodic Maintenance and Service
Periodic maintenance of the gas engine and auxiliary equipment, which are the main components in cogeneration facilities, involves defined activities performed at regular intervals.
Preferably, inspect the entire cogeneration facility daily and check for any oil or water leaks or unusual noises. Regular routine servicing is essential and should be carried out by trained engineers and technicians. Maintenance and service generally include:
- Checking and replacing spark plugs
- Changing oil/sampling and safely disposing of waste oil
- Replacing oil/air filters
- Calibrating the engine and adjusting valve settings
- Checking battery status
- Verifying emission test settings
Step 2 – Enhance Safety by Monitoring Parameters and Performance
Install control and measurement devices in your cogeneration system to enable live monitoring and record critical system parameters. These include:
- Temperature, Pressure, Flow
- Fuel consumption
- Electricity production
- Useful heat utilized
- Operating hours
You can’t measure what you don’t monitor. By measuring performance, you can extend the benefits and service life of your system. Monitoring also provides early warnings related to necessary maintenance activities. Performance monitoring is also essential to demonstrate compliance with quality requirements under the CHPQA program.
Step 3 – Use Live Monitoring Techniques to Prevent Major Issues
Utilize a web-based platform for remote monitoring to detect any potential problems in advance. Use the data to make adjustments in the operation and schedule maintenance visits. By adopting a preventive maintenance approach, you can optimize system performance and maximize production. Live monitoring provides maintenance input, can extend the life of components, and reduce downtime during operations.
Step 4 – Plan Your Maintenance Program
Maintenance begins during the design phase of a project, where good access for servicing and repairs is crucial. The efficiency of a cogeneration system running at partial load will decrease, and maintenance costs will increase. Therefore, maintenance is essential for ensuring overall cost-effectiveness throughout the system’s lifespan.
When planning, ideally schedule maintenance outages during times when energy demand is below normal. Maintenance and repair of the machine are best performed during the summer when heat demand is lower. Alternatively, maintenance can be performed simultaneously with other specific equipment inspections, such as boiler checks.
Step 5 – Define the Right Maintenance Package
Achieve established performance guarantees and warranties by servicing cogeneration units in accordance with the manufacturer’s instructions.
Expert firms offer comprehensive maintenance and service plans that include:
- Routine servicing
- Remote performance monitoring and fault diagnosis
- Equipment repairs
- Guarantee of CHP availability during operation
Operation and maintenance packages that cover the entire operating system are also available to ensure maximum performance of cogeneration operations.
Key Considerations:
- Periodic inspections and servicing are vital and should be conducted by trained engineers.
- Expert suppliers have the necessary knowledge about design and maintenance to provide the best after-sales service.
- Cogeneration operations should be monitored for conditions and performance using remote monitoring.
- Performance reports are required for compliance with quality management systems.
- Major maintenance outages are best planned during periods of low operational demand.
- Ensure you have the right maintenance package for your system to maximize the benefits of cogeneration.
