 |  | Project: GM Wentzville, MS - Coal to Natural Gas Conversion
Client: General Motors
Scope: Lipten is converting two coal-fired boilers to fire natural gas at the GM Wentzville assembly facility in Missouri. Lipten has converted many boilers from coal to natural gas firing; several of them at GM facilities.
The project includes installation of new vertical-firing natural gas burners. Vertical burners were chosen instead of horizontal burners for this application to provide: optimum flame geometry for the specific furnace configuration, improved water circulation patterns, improved thermal efficiency, better overall boiler performance, avoidance of flame impingement and simplified operation. The project also includes new forced draft fans, natural gas supply systems, electrical modifications, custom Programmable Logic Controller (PLC) control systems from Lipten’s Controls Division and additional system modifications required to convert coal boilers to fire natural gas. This project will be completed by the end of 2013. |
