It is of great significance to reduce the consumption of fuel oil for pulverized coal fired boilers in China. Minimal-oil ignition technology is an effective solution to save fuel oil. The principal, system components and industrial applications of the minimal-oil ignition technology are introduced in this paper. The concretely adopted schem involves that the small gasified oil gun is adopted to replace the starting-up oil gun, and the concentration device is arranged to realize the concentrationstaged combustion of pulverized coal, without any influence to the boiler's performance. The numerical simulation and experiment results indicate that the minimal-oil ignition technology can be applied in startup, stopping and aided combustion in low load condition of pulverized coal fired boilers. The average fuel oil consumption after retrofit is reduced by over 90%. The minimal-oil ignition system is simple, operation convenient and little maintenance is needed. Its extensive application can bring prominent economic and environmental advantages.
