More Information
Summary:The invention relates to a 300MWCFB boiler and a distribution method for oil shale for combustion. Implementation of upsizing of a circulating fluidized bed boiler for the oil shale for combustion becomes an important topic for technological development of the circulating fluidized bed boiler. The 300MWCFB boiler for the oil shale for combustion comprises a boiler body; a boiler cylinder (11) is arranged above a square hearth and along the center of the hearth; a slag cooler (9) and an under-bed start-up burner (10) are arranged below the square hearth; a water cooling screen (9), a high-temperature re-heater (6) and a high-temperature super-heater (7) are arranged in the center area of the upper space in the square hearth; steam and water separators (3) are symmetrically arranged at the two sides of the square hearth; the upper parts of the steam and water separators are connected with the square hearth via inlet flues (2); the lower parts of the steam and water separators are connected with the square heart
