Reliability, Availability, and Maintainability of the Heat Recovery Incinerator at Naval Station Mayport.
Abstract
The heat recovery incinerator (HRI) at Naval Station Mayport, Fla. was studied to determine the expected long-term performance of the HRI. The data, which were collected from October 1980 to August 1983, were analyzed for reliability, availability, maintainability, waste incineration rate, thermal efficiency, and steam cost. Actual results for incinerating waste to produce steam were: reliability 58% (75% of design); availability 82% (91% of goal); maintainability 0.10 man-hr/ton (100% of goal); thermal efficiency 48% (87% of goal); incineration rate 1.75 tons/hr (105% of goal); and cost of steam $6.05/MBtu. The HRI was expected to save $26,600/yr from landfill reductions and $102,320/yr from energy savings. The principal reasons for the shortfalls in performance were shortages of solid waste, and failures in the crane, feed rams, ash conveyor, front-end loader, feedwater equipment, and induced draft (I.D.) fan. Corrections have been made in HRI operation to improve performance of the ash conveyor. Recommendations are made on additional maintenance procedures, and on equipment design criteria to improve plant operation and for future plant design. (Author).
