Air emission control services for energy production
Valmet’s service offering is designed to match your specific needs, whether it's enhancing plant availability, environmental performance, or both. Depending on your requirements, the service solution can be provided as a one-time delivery or as a longer-term partnership through service agreements. By working together, we can ensure maximized reliability and optimized performance of the production process.
High availability and supply reliability
Optimized and predictable operation cost
Sustainable operation by regulations
Increased equipment lifetime
Convert the existing Electrostatic Precipitator (ESP) into a hybrid filter to meet allowed particulate emission
Lower the particulate emissions and unburned compounds in the flue gas and ensure consistent performance by converting the existing Electrostatic Precipitator (ESP) into a hybrid filter. It’s a cost-effective solution that doesn’t require any major changes to the site layout and gives more efficient flue gas cleaning.
Improved capacity and equipment lifetime for electrostatic precipitators (ESP)
With the right service, we can increase equipment lifetime, and improve capacity and equipment availability. Whether you are looking to improve efficiency and reliability, or you want professional help for your shutdown management to minimize operational downtime, we have you covered. If you are looking to modernize your equipment, we offer refurbishments and upgrades to improve performance and adapt to new operational requirements. Our services are available for all ESP designs including other OEM equipment.

The flue gas scrubber service will extend the lifetime of your equipment and help you achieve performance targets such as efficiency, pressure drop, and power consumption. The service scope includes:
- Inspection of scrubber internals
- Troubleshooting, site audits, and process studies
- Maintenance and exchange of internal parts
- Renewal of washing pipes
- Repairs and modifications to flue gas inlet channels
- Maintenance of auxiliaries, such as water treatment and additive dosing systems
- Retrofits/Modernizations to maintain equipment reliability or align equipment with changed capacity or fuels
Improved plant efficiency through flue gas condensing and heat recovery upgrades
Flue gas condensing and heat recovery services will improve the condensing process and/or heat recovery, generate increased plant efficiency and lower condensing temperatures to meet stricter emission limits. A site audit and process study typically serve as the initial steps to understand the best and optimal solutions.
Different solutions are available for various needs:
- Improvement of scrubber packing structure for better heat capture from flue gases
- Installation of additional heat exchangers or extra plates in existing heat exchangers
- Addition of an absorption heat pump to the existing scrubber process to enhance heat transfer to district heating
Bag house filter service to meet emission limits
With in-house manufacturing of filters and extensive knowledge of the filtration process and fabric properties, we offer various materials for different flue gas conditions. The baghouse filter service helps you achieve emission limits, estimate the remaining lifetime of the bags, and minimize unplanned stops.
We also provide baghouse filter additive injection for capturing gaseous pollutants.
Our baghouse service offering includes:
- Inspection of filters and additive feeding
- Troubleshooting, site audits, and process studies
- Laboratory analysis for monitoring bag condition and estimating lifetime
- Exchange of filter bags and support cages
- Maintenance of auxiliaries like flue gas dampers or cleaning air pulsing system
- Maintenance of chambers and hoppers
- Design upgrades/new filter fields for changed operational conditions
Improved forecasting of maintenance costs with SCR services
Selective catalytic reduction (SCR) services assist in maintaining NOx or NH3 within the right limits, allowing for better forecasting of lifetime and maintenance costs. The service offering includes:
- Inspections
- Troubleshooting, site audits, and process studies
- Delivery, maintenance, and exchange of internal parts
- Installation of new catalyst blocks and laboratory analysis for monitoring catalyst condition and estimating lifetime
- Retrofits and modernization
