102. PC-Based Windows NT Integrated Operating System for Electrostatic Precipitators Lakshmanan R., Arunachalam S., Kesavan V. (BHEL Journal, December 2003, pp. 52–58). Abstract Electrostatic Precipitator (ESP) is the most widely used device for particulate emission control. This paper presents the design and development process of PC-based Windows NT Integrated Operating System (NT-IOS) for electrostatic precipitator. In the technology-driven market, it becomes mandatory to upgrade the ESP's IOS to the state-of-the-art technology. In this process, the existing IOS has been re-designed for the Windows NT platform to meet customers’ stated and implied requirements. This paper explains the development life cycle of this project, starting from requirement specification to commercialization. NT-IOS is a master, which controls and monitors all the ESP controllers from UCB/ESP control room. The web server running in this package serves the ESP status to all the authorized users through their enterprise local area network. The latest software tools like VB6.0, Graphic server and Winhelp Office were used for this development. After a thorough lab test, the software was tested at Mettur TPS and Ramagundam STPS successfully. Customer feedback during these site trials was incorporated, and this system has been commercialized in Satpura and Kothagudam projects. All future contracts would be supplied with NT-IOS. Top Keywords IOS, BAPCON, RAPCON, Transformer-rectifier, Visual basic, Graphic server, Tomcat server, ROBO-help, MSComm, MSFlexGrid, V-I curve, Opacity monitor, Boiler load, Analog and digital add-on card, RS232/Current loop converter.
