Two modern all-coal-fired 74700 dwt bauxite carriers built by Mitsubishi Heavy Industries for an Australian Shipowner employ a twin-boiler installation of V2M-9S design which fires solid coal by spreader-stoker system. A microcomputer-aided automatic coal-fired boiler combustion control system 'COAL MACCS' can control even delicate boiler load changes. The shipboard coal and ash handling operations also are fully automated. The high degree of automation and low manning level are comparable to those of the oil-fired marine steam generating plants, enabling the ships to meet Lloyd's register's unattended machinery space requirements. Comparative studies show the coal-stoker firing, as against the pulverized firing and fluidized bed firing techniques, to retain its predominance as the most reliable coal-firing method for some time to come.
