NTNN Quest Engineering Private Limited Nungambakkam, Chennai, Tamil Nadu

NTNN has acquired an unrivalled reputation in the field of supply of Replacement Parts for Electrostatic Precipitators, for both Dry & Wet designs. To bring comprehensive facilities offering ESP parts to customers, a pioneering initiative has been taken for the first time that we offer replacement parts for all makes & types of both Wet & Dry ESPs under one roof. We, at NTNN,started our facility with manufacturing parts for just for Dry types of ESPs. But subsequently we are equipped to supply O&M spares for Wet Electrostatic Precipitators(WESP).

a. Hopper Heaters: The fly ash from the flue gases passing through the ESP fields are collected in the hoppers below and then carried by ash handling system. Due to moisture content and low temperature inside hoppers, choking & accumulation of fly ash occurs frequently affecting the performance of ESP. Heaters are provided on all 4 sides of hoppers to maintain temperature inside hoppers for effective flow of fly ash to ash disposal system. High Temperature Hopper Heaters are manufactured from incoloy for ESP application for long life. These are designed to withstand Shock & Vibration and when installed on the sides of Hopper and insulated, they provide a blanket Heat Coverage effect. b. Insulator Heaters: For optimum performance of the ESP the temperature inside the ESP should be maintained suitably. The air ingress through the insulator openings are to be kept hot and for this purpose, heating elements are provided on the Insulators.

NTNN offers replacement Emitting / Discharge Electrodes for many Precipitator designs. The standard Emitting Electrode is designed for longer life with a high tensile strength. For Discharge Electrodes of Alstom style ESP’s, the shrouded hook ends of Electrodes are manufactured with the Electrode wire inserted through the shroud prior to forming the hook, thus eliminating the requirement for crimping. We manufacture different designs of Discharge Electrodes to OEM standards, using varieties of raw materials. There are many more designs & shapes of Discharge Electrodes, which are part of our product range, but not displayed below. Please contact us for all your requirements of Discharge / Emitting Electrodes.

Collecting Plates / Electrodes are manufactured in our groups’ facility.
