When existing dedusting systems are no longer able to achieve the required exhaust gas emissions, either because of existing equipment design limitations or due to increased plant capacity, it is necessary to consider upgrading or completely replacing the existing dedusting plant.
BoldEco has carried out several dedusting plant upgrades and has acquired extensive know-how in the study and execution of such projects.
When considering such upgrades or conversions, not only must the ultimate plant efficiency be taken into account, but also the time required for conversion and integration with existing equipment due to short kiln shutdown requirements.
Reverse gas or shaker to pulse jet
Modifications to gas distribution
Application of various filtering media
ESP to pulsejet fabric filter
Conversion to hybrid design
Redesign of inlet gas distribution section
Replacement of water atomizing lances
Replacement of regulation control system
This is a gallery of a recent Electrostatic Precipitator (ESP) to Pulse Jet Fabric Filter (PJFF) project carried out for a cement customer. The customer had a need to complete the tie-in within 2 weeks. The tie-in actually took 1 week, providing the customer 1 additional week of production.
The project had the following requirements:
1. 2 week shutdown
2. Re-use existing materials handling system
3. Replace Fan
4. Install new PJFF housing with walk-in plenum
5. Upgrade existing Spray Tower to air assist sprays
6. New electrical components to be pre-tested
The customer was able to reduce a 2 week planned shutdown to a mere 7 days as a result of our modified design.
