John has worked on my projects as a boiler specialist. We have hired John and Lipten two times, and are in the process of developing a third project. Both times John has provide valuable advice and service to help us to convert boilers from coal to natural gas, to engineer a new economizer for an existing boiler, and to help us develop a plan for a boiler at the end of it's lifecycle. John's attention to detail, and timely advice has made Lipten our supplier of choice for boiler systems. John has provided complete lifecycle support from capital planning to execution of replacement systems. —Project Manager, General Motors |

 |  | 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: 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: DaimlerChrysler World Headquarters
Client: DaimlerChrysler Corp. - Auburn Hills, MI
Scope: New 45,000,000 Btu/hr high temperature hot water generator with low NOx burner, forced draft combustion air fan, flue gas recirculation system, main and pilot gas valve trains, SLC-based combustion control and burner management systems, all required field instrumentation and a stack gas oxygen analyzer. |

 | | 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: NAO Facility
Client: General Motors Corp., Energy & Utilities Services - Pontiac, MI
Scope: Scope: Converted rail-spur storage facility to house two 100,000-pph D-type and one 100,000-pph O-type natural gas fired package boilers, deaerator system with feedwater pumps, surge tank with transfer pumps, chemical feed systems, burner management & combustion control systems, boiler plant master control system, PC-based plant monitoring system. Unique to this project: arranged transporation of two re-conditioned boilers from a GM facility in NY and brokered and arranged transport of a third boiler from another manufacturer's facility in Detroit. |
