Unicon Electrostatic Precipitators

• UNICON has a credential record of success in designing, engineering, fabricating, supplying, erection and commissioning of electrostatic precipitator (ESP).

Lower emission

• Designed to reduce the emission rate to as below as 10 mg/Nm³ emissions.

Easy maintenance

• The electrode system is so designed that approach to any level is possible for inspection and maintenance.

Engineered for longevtiy

• High performing and long lasting electrostatic precipitator with a lower cost modules

• Proven Particulate Matter Removal <10mg/Nm³
• High Availability
• Low Maintenance
• Reduced breakdown
• Most Economical Design
• Lower Operating Cost
• Optimum Performance under Varying Load Conditions

Our ESP design will incorporate CFD for even distribution of gas inside ESP to ensure the complete utilization of collecting area Spiral/Rigid Electrodes with Tumbling Rapping System We offer Spiral/Rigid Emitting Electrodes to ensure the proper Corona generation inside the ESP for better collection efficiency. Individual Collecting electrodes are suspended from top to form a curtain. This also ensures that the Collecting system is not bulky and thus ensures good rapping characteristics.

GD Testing

• Unicon is equipped to carryout GD testing of any make ESPs with more than 35 years’ experience in the field.
• Improve the performance of ESP
• Meet the emission legislation by increasing equipement collection efficiency.
• Drive down the operational cost with improved quality.
• Cost Effectiveness.
• Separate shutdown is not required for implementationReduce the shutdown time.

Test Procedure

• Air flow through the ESP chamber is established by running the ID, FD & PA air fans at suitable loadings. Once the flow is established by preliminary measurement, the loading of fans and furnace draught are recorded so that the same condition can be maintained for all subsequent tests.
• The velocity measurements are made inside and across the precipitator chamber, between the first and second field, using vane type anemometer. The measurement points are distinctly marked on the trailing edge of the collecting electrodes of the first field.
• The vertical space between the points is 1000mm, leaving a gap of 500 mm from top and bottom of the collecting electrode. The readings shall be taken at every alternate collecting electrode spacing.
• The test is conducted on a trial basis and hence more than one trial may be required before a gas distribution meeting the acceptance criteria is obtained. Adjustments if required will be carried out based on the tests, modifying the location of deflector/ throttling plates. The above is repeated till the desired distribution meeting the acceptance criteria is obtained.
• The acceptance criteria for gas distribution is that the coefficient of variation should be less than 20 %.

• Patented by Heavy Water Board, Department of Atomic Energy.

• Unicon is licensed partner of HWB for manufacturing, supply and installation of AFGC Systems.

• Unicon signed a MoU (Memorandum of Understanding) with HWB.

• This technology results in reduction of SPM emission drastically from a level of 600-700 mg/Nm3 to 20-70 mg/Nm3.

• The quality of coal, increased ash content, ash resistivity and many other factors result in the lower performance of ESP and consequent increase in SPM. Many technologies have been tried out for improving the performance of ESP but limited success. With Environmental Standards being continuously upgraded for cleaned air quality, time has come for upgrading and developing new technology for overcoming the above problem.

• The technology developed for flue gas conditioning to reduce the SPM emission level is extremely safe and the performance of the system is truly rewarding.

• The simplicity is that it can be integrated in the existing plants for reduction of SPM with minimum modifications and without shutdown time at low cost. This new technology is a boom to the existing equipments which were installed way back.
