Upgrading a precipitator can be an economically attractive possibility if:

1. the mechanical or electrical equipment are worn out
2. the production is increased,
3. the emission requirements are made more rigorous,
4. there has been a change of fuel or raw material.

In order to ascertain a qualified conclusion of the degree of upgrading needed, we will recommend a careful professional investigation, thereby enabling us to find the most qualified solution for you.There are four main areas to be investigated:

1. Precipitator design and operating data
2. Flue gas characteristics
3. Dust characteristics
4. Operating Conditions

The precipitator size in form of volume and plate area may be judged to be:

- Adequate to give the desired dust emission
- Too small to give the desired dust emission

In the first case there is no need to change the physical dimensions. Depending on the age and condition of the precipitator improvements may be achieved by: Replacement of internal mechanical parts:

 
The above images shows splitting up large fields into smaller separate fields.

Digital controllers are fast reacting and can implement sophisticated control strategies. Upgrading the control system is an inexpensive method for reduction of precipitator power consumption, and improvement of precipitator performance.

• Replacement of automatic control system.
• Installation of pulse generators.
• Water conditioning or upgrading of existing conditioning tower.
• Flue-gas conditioning.

For further details regarding electrical re-builds kindly see our product presentation: ESP High Voltage Control Systems.

Installation of Pulse COROMAX on ESP all makes, either on the ground or on the ESP roof, depending on either design or strength of roof.

In the second case there is a need to change the physical dimensions of the installation, involving  the following solution:

New precipitator in series with the existing one.
New precipitator parallel to the existing one.

We have with success installed our Coromax Pulse systems on existing precipitators and achieved the expected emission reduction - often without modification of the precipitator itself. The down time of the production line can be limited to a day or two.

In Pohang Iron and Steel Works in South Korea, we have upgraded large existing precipitators to the given performance guarantees which was followed by repeat orders - an acknowledgement of the clients satisfaction.

Whether it is new precipitator installations or upgrading of existing units, we have the complete expertise of analysing the given situation and the product range to meet this demand as well as the skill and knowledge to implement the system with a minimum of disturbance to the production.
