Thermax Opticor® reduces emissions by 20% from ESP without equipment replacement

Project overview

A leading sugar manufacturer in Thailand was experiencing a gradual decline in electrostatic precipitator (ESP) performance after more than a decade of operation.

With tightening emission norms and the need to maintain efficiency in a biofuel-fired boiler environment, the customer sought a solution to improve ESP performance without replacing existing equipment.

Challenges

Declining ESP performance due to ageing electronic controllers and outdated spark regulation.
Risk of emissions exceeding permissible limits over time.
Difficulty in maintaining emissions below 30 mg/Nm³ in biomass-fired boilers with high moisture and fibrous fuel content.
Requirement to improve performance without complete ESP replacement.

Solution

Installed Thermax Opticor® advanced voltage controllers across both ESP units.
Enabled real-time digital spark and voltage control with improved pulse energy regulation.
Enhanced mA/kV delivery to ESP fields, improving dust charging and collection.
Provided high adaptability to varying fuel compositions and load conditions.
