ANDRITZ SIR (Switched Integrated Rectifier) models

The SIR (Switched Integrated Rectifier) reduces the particulate emission level and improves overall ESP performance without a need for costly extensions. ANDRITZ provides a robust and reliable technology with the highest expertise and service capabilities in clean air technologies. A wide range of its advanced, high-voltage power supplies for electrostatic precipitators are now available from ANDRITZ.

SIR4 180

We proudly present SIR4 180 – the largest in our family. There are three versions, with 380, 400 and 480 V input voltage. This model is designed for larger precipitators to deal with a higher current charge and consists of three power electronics units.

• 70kV/2500mA

• 85kV/2100mA

• 100kV/1800mA

SIR4 25,35 & 60

These are the smallest models and are designed for smaller precipitators. These models will replace our SIRE model, which has been discontinued. They consist of only one power electronics unit.

There are four models available, with a selection of input voltages 380, 400 and 480 V:

• 85kV/400mA

• 85kV/700mA

• 70kV/800mA

• 60kV/1000mA

• 100kV/250mA

SIR4 102/120

The mid-range and our most popular models. Comes in three versions, for 400, 480 and 500 V. These models have two power electronics units.

• 70kV/1500mA

• 85kV/1200mA

• 70kV/1700mA

• 85kV/1400mA

• 100kV/1200mA

Features:

Limited free space needed, no cabinet space required.
Installation and commissioning time reduced to half a day compared to several days for a conventional T/R and its control cabinet.
SIR loads the 3-phase mains symmetrically.
An SIR typically uses approximately 65% of the kVA required by a conventional T/R and can still provide the same kW to the ESP. This feature has an impact on operating cost savings by consuming less kVA.
SIR has an efficiency of more than 95% and up to 97 % with our SiC model. Its smaller-sized cables result in cost savings for cabling material
Ease of installation (due to smaller size and weight) and less cabling reduce installation time (and potential rebuild costs when upgrading).
Robust and proven design solutions.
Modular design where the structure remains on the roof during maintenance.
Minimized downtime in the event of component failure (less than 1 hour) thanks to standardized spare parts.

Fabric Filters (FF)

The Fabric Filter (or baghouses or bag filters) uses a filter media to separate Particulate Matter (PM) from the flue gases. The Particulate Matter are deposited at the surface of the fabric filter which may be made of different materials depending on the flue gas physical and chemical composition. The dust is removed periodically when cleaning the bags.

Hybrid Filters

Hybrid Filter is a combination of ESP and FF with several configurations (in serie and in the same casing (integrated) or in separated casings in serie or in parallel (separated)).

EKP Unit 2 - ANDRITZ Wet Electrostatic precipitator (WEST)

Wet Electrostatic Precipitator (WESP)

As for the dry ESP, the wet ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by flushing water.

Dry Electrostatic Precipitator (ESP)

The ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by a knocking action.
