Guest Lane Kadel Posted March 23, 2008 Report Share Posted March 23, 2008 The site is configured with two Lurgi multi-hearths, bubbling fluidized bed furnaces with numerous modifications. Post combustor, super-heater, then into the steam boiler. Boilers process the steam into a turbine, which operates the Alstrom 18 megawatt generator. The facility,commissioned in 1988, was designed to handle large volumes of cow manure (1200 tons/day) as a waste-to-energy plant. The existing site houses an agri-waste to energy facility consisting of a power generating station and support buildings. The 18-megawatt power generation facility is located in an industrially zoned region of the County and was initially developed in 1986-1988 with a Conditional Use Permit. The power plant facility is composed of a number of buildings and features. A large storage building on the east side, which was used to store fuel (manure). The main power generating portion of the facility is composed of (2) large furnaces, boilers, ductwork, baghouse, exhaust stack, turbine, generator, transformers, cooling towers water treatment fuel handling system, and ash handling systems. A small metal building containing offices, lab, control room, battery room, switchgear room and locker room facilities. A shop building for housing trucks and equipment. A raw water storage pond, septic and leaching systems and a storm-water runoff basin. The site is enclosed by chain link fence. All utilities are installed underground except electric transmission lines which are overhead. STRUCTURAL FRAMING & FOUNDATIONS The structural steel framing and miscellaneous steel components are in good condition, no scaling of the steel components were observed. All connections of the structural steel members were intact and in good condition. The contract construction drawings for the foundation indicated that the plant is resting on driven concrete piles with concrete pile caps and footings supporting the structure. The steel column base plates rest on concrete pedestals, which are connected to the pile caps. The concrete pedestals are cracking and sprawling, however, after chipping at the pedestals the concrete is loose only at the perimeter of the base plate and not below the ground surface. While chipping at the concrete pedestals, it was also observed under the face of the base plate was solid SYSTEMS INSPECTED Steam Turbine and Generator Multi‑Hearth Furnace A & B Compressed Air System Condenser System Baghouse Fuel Unloading and Direct Feed to Top of Furnace System Fuel Storage and Bucket Elevator Fire protection System Electrical Switchgear and MCC rooms have a Halon System installed System Control Room has a Halon System Installed Office building has fire sprinklers Plant area has ground level fire hydrants Water Treatment System The existing water treatment system was not used after a few years of operation, an outside company supplied a system and treated the water which is no longer on site. The existing water treatment system equipment is in good condition. System Controls Supply Water The supply of water is through a channel into an onsite lake. The condition on the lake appeared to be good condition. The pumps for the filling of the lake are in good condition and are being used. Fuel Storage Area There is a fuel storage area for diesel and gas tanks, the tanks and the concrete containment looks good. Emergency Fire Pump & Generator There is an emergency fire pump and generator located next to the lake. Both the pump and the generator are in good condition and were observed in operation.
