SOLAR powered “ELECTRODIALYSER” for Boiler feed

Salient Features:Energy efficient

Online TDS monitoringAutomatic in working

Proposed model :

ELECTRODIALYSIS SYSTEM

The Aim is

p To Reduce the Power Plant operating Energy by introduction of the Renewable Energy (Solar PV ) to run the accessories (like feed water treatment plants for boiler) of the power plant.

n Calculation of energy savings due implementation of the Electrodialyser to avoid the frequent blowdown in conventional power plant boilers.(simulation of results by MATLAB and Experimentation by a Model)

È The turbidity of the boiler feed water is constantly monitored by the online TDS monitoring unit and results are reported to the control unit.

The control unit selects the capacity of current flow to the dialyzer and the accordingly the TDS is reduced into sludge form near the electrodes chamber of the Electrodialyser.

e The Electrodialyser is stopped working as soon the water’s turbidity is reduced to the soft water as required for boiler to reduce the scales.

s The online monitoring of the TDS gives the signals to the control-unit , for taking the suitable action to save the energy.

p Solar PV is supplying the power to the Electrodialyser.

e The Solar PV power is selected to feed the power unit only when the charge controller is giving a positive signal for the availability of solar power in the battery bank, otherwise the Electrodialyser would defautly run by the power generated by the Grid Power as backup.

The Controller unit is connected Grid power, so as ensure the tolerate the annual intermittent supply of the solar power should not affect the control of the Electrodialyser.

l The energy savings done by implementing the renewable energy is calculated and also the pay back period.

Designing Fabrication of the ELECTRODIALYSER

Designing and fabrication of the charge controller.

Designing and fabrication of the total setup of the demo model (INTEGRATION).

Simulation of the results of the energy savings.

Experimenting the results of the energy savings in the demo model.

Comparing the reports of simulation and the demo model.

This is a proposed time plan which is viable to changes as per the procurement of the objects and due to debugging the technical errors in fabrication of demo model
