|Project: Boiler Conversion CFD Modeling|
Scope: Lipten has provided engineering support for many boiler conversions, including 3D modeling and Computational Fluid Dynamics (CFD) modeling of the boilers. This work ensures the final design has proper air side heat distribution and velocities.
|Project: 210,000 lb/hr Boiler Coal to Gas Coversion|
Client: GM Wentzville
Scope: After converting two similar boilers at the GM Wentzville facility, Lipten was awarded another contract for the conversion of a third 210,000 lb/hr boiler.
|Project: Coal to Natural Gas Conversion|
Client: Nexteer Automotive
Scope: Lipten converted two coal-fired boilers to fire natural gas. The work included demolition of existing grates, stokers, coal and ash hoppers. Lipten then installed new draft fans, furnace floors, support plates and a structural steel system required to support the new vertically fired burners. The project also included providing all new Burner management and combustion control systems along with variable frequency drives to control the speed of the FD and ID fans.
|Project: St. Mary’s College Coal to Natural gas Conversion|
Client: St. Mary’s College
Scope: Lipten was contracted to provide full Design & Build Turn-key Coal-to-Gas Conversion, and powerhouse renovations. Lipten converted two 50,000 pph field erected coal boilers to vertically up-fired natural gas with fuel oil backup. In addition, a new 30,000 gallon fuel oil storage system, a new diesel generator backup system and a new deaerator system were installed.
Lipten’s scope also included a re-furbished triplex softener system, a new power distribution system, three new burner management & combustion control systems, a plant master system and a dual PLC based plant monitoring system. An entirely new instrumentation control valve and control device package was also included. Lipten provided engineering, project management, start-up, training and commissioning.
|Project: 420,000 lb/hr Boiler Coal to Natural Gas Conversion|
Client: General Motors
Scope: Lipten converted 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.
|Project: Ford Motor Company, Cleveland|
Client: Ford Motor Company - Dearborn, MI
Scope: Demolition of existing grates, stokers, coal and ash hoppers and combustion fans. Installed furnace floors, support plates and a structural steel system required to support the new vertically fired burners.
|Project: GM Service Parts Operations - Swartz Creek|
Client: General Motors Corp. - Pontiac, MI
Scope: Converted three 45,000-pph field erected coal fired boilers to front wall fired low NOx natural gas fired burners, FD fans, VFD and control on ID fans, fuel trains, extensive tube repairs and modifications, spray-tray deaerator system with feedwater pumps, duplex softener system, chemical feed system, blowdown heat recovery system, three burner management and combustion control systems, boiler plant master control system, PC-based plant monitoring system.
Lipten also provided full Design, Engineering, Project Management, Site Management, Startup and Commissioning services for the systems as well as operator training. Local skilled trades were utilized for Demolition, Asbestos Abatement, Cement Work, Boilermakers, Pipe Fitters, Mechanical Rigging & Installation, Electrical Installation, Painting and Insulation. Two Rental Boilers, a Feedwater Trailer and tie-ins were included to allow for complete powerplant shutdown during the conversion
