Representative Projects:
Circulating Fluidized-Bed/Bubbling Fluidized-Bed (CFB/BFB)
- Southern Illinois University, Circulating Fluidized-Bed Boiler, Carbondale, Illinois
This project consisted of installing a 100,000 lb/hr circulating fluidized-bed boiler. Steam is generated at 650 psi and passes through a new back-pressure turbine generating 3,100-kW. The project also included a new boiler enclosure, control room and locker room, distributed control system, deaerator and boiler feed pumps, demineralizer and condensate polisher, extension of existing coal handling system, and a new 480-volt power center. Upgrades to the existing heating plant included a new single baghouse on two 80,000 lb/hr traveling-grate boilers, interconnecting breeching, refurbishment of one traveling-grate boiler with new pressure parts, economizers, ID fans, demolishing stack, 480-volt power center, and boiler control systems. The first campaign was to prove this biomass material can be processed and conveyed into the boiler without any deleterious impacts on the unit, its performance, or its emissions.
- University of Missouri, Bubbling Fluidized-Bed Boiler, Columbia, Missouri
This project included demolition of an existing coal-fired circulating fluidized-bed boiler, new 150,000 lb/hr bubbling fluidized-bed boiler firing 100% biomass, and new material handling equipment and storage silos for coal and biomass.
Co-Generation
- University of Missouri, Gas Turbine/HRSG Addition, Columbia, Missouri
This project consisted of the installation of gas turbines and heat recovery steam generators. The addition adds an electric generating capacity of 27-MW and steam generating capacity of 250,000 lb/hr of 950 psig steam. In addition, the project includes a new 24,000 square-foot building, control room, boiler feed pumps, gas compressors, chillers, cooling tower, and chilled water pumps for the new equipment.
