RJM conducted a detailed review of the Furnace Protection System at a down-fired coal power station, AES Mong Duong II, Vietnam. One of the works included in this project incorporates the review of the current Loss of Flame Protection system against the NFPA 85 Code.
Site testing results have shown that the flame detectors failed to perform according to its intended safety functions, due to the equipment positioning, which required the detection of individual burner flames as seen in most front-wall fired power stations. RJM has successfully completed the development of a new Master Firing Trip Functional Design that will replace the existing system and allow the plant to operate significantly safer.
Furthermore, RJM is experienced in the Management of Change processes and is currently on-track to implement the identified safety enhancements to the plant. Historical combustion upgrades in this plant have yielded significant improvements on furnace stability in AES Mong Duong II, resulting in reduced frequency of boiler trips, leading to reduced start-up and shut-downs which contributes to increased plant availability.
