MHI has long been engaged in low NOx combustion R&D and put them into practical use. Recently, MHI has developed the compact advanced-pollution minimum (A-PM) burner for coal firing boilers, which has excellent compactness and improved combustion performance. By combining this burner with our in-furnace NOx reduction Mitsubishi advanced combustion technology (A-MACT) and the Mitsubishi rotary separator (MRS) pulverizer, we have completed an excellent coal combustion system that, for instance, enables the existing boiler to be retrofitted to make up for installation limited space. This technology was applied to the 300MW coal-fired boiler of the Talin power plant, Taiwan Electric Power Company and excellent combustion performance was confirmed. Improved operability and maintenance were simultaneously also confirmed.
