|Project: 70,000 lb/hr Steam Boiler and Condensing Heat Exchanger|
Client: Food Manufacturing Company – Nebraska
Scope: This project involves engineering and installation of a 70,000 lb/hr steam boiler and condensing heat exchanger. Lipten designed the custom controls associated with the boiler and heat recovery system.
The condensing heat exchanger utilizes the exhaust gas from the boiler to heat makeup water for delivery to the Deaerator, thus reducing the fuel (steam) requirements of the Deaerator (boiler) to bring the water up to saturation temperature.
A typical boiler flue gas heat exchanger (known as an economizer) would be designed such that heat transfer would maintain the flue gas temperature above ~300°F so that the water vapor in the flue gas does not condense and ruin the stack, heat exchanger and boiler. Since this system is specially designed with stainless steel components it can transfer more heat to the make up water from the flue gas, thus increasing overall central utility plant efficiency.
|Project: New Central Energy Plant, Chicago, IL|
Client: Food Manufacturing Company
Scope: This project involves a turn-key steam and chilled water Central Energy Plant (CEP) for a food manufacturing company in Chicago, Illinois. The project also involves the demolition of an abandoned five-story refinery building, tank farms and warehouse. The new facility’s premium control systems provides a high degree of monitoring capabilities and controllability. Safety, reliability and efficiency are important aspects of all Lipten central energy plant projects.
Lipten’s 3-D model of the Energy Center includes the building, support steel, equipment, piping and instruments. The 3-D model creates a virtual energy center that enables Lipten Engineers and the client to “step-inside” and view the Energy Center prior to construction. This allows design modifications to be made at the engineering phase rather than after construction resulting in a much more desirable outcome at less expense to the client.
|Project: Custom Central Energy Plant Controls – Madison WI|
Client: Food Manufacturing Company
Scope: Lipten provided three (3)COMBUSTIONPAC™ boiler control systems and a balance of plant MASTERPAC™ control system. At this location two boilers can meet full steam demand and the third boiler is ready for stand-by. The boilers can be remotely sequenced such that equal operating hours of all three boilers can be achieved throughout the year. Lipten's custom controls allow the three boilers to share two heat exchangers. Flue gas and process water is directed such that optimal heat transfer is achieved regardless of boiler sequencing.
Lipten’s scope included new control systems as well as startup and training of the plant operators on the Lipten control systems. A comprehensive plant Standard Operating Procedure (SOP) with photos, equipment tags and step-by-step instructions was also developed by Lipten.
|Project: 1500 HP Firetube Boiler|
Client: Meat Processing Company
Scope: Lipten provided engineering, procurement and installation of a new Firetube boiler. In addition, Lipten provided an Economizer a PLC based Boiler and Combustion control panel and a balance of plant control panel. The fuel train was designed to accept Natural Gas or Tallow with an option for the addition of biogas.
|Project: Pulaski County Wood Fired Systems|
Client: Egg Production Facility
Scope: Renovation of wood fired air heater including new air-to-air heat exchanger, installation of new dampers, fabrication and installation of bypass stack, two exterior/interior ducting systems, and new PLC-based control system with seven variable frequency drives.
