Abstract
The invention relates to a circulating fluidized bed boiler for a papermaking thermal power plant. The circulating fluidized bed boiler comprises a tail smoke well, a separator, a material returning device and a hearth, wherein the bottom of the hearth is communicated with the material returning device; the top of the hearth is communicated with the separator; the top of the separator is communicated with the tail smoke well; the bottom of the separator is communicated with the material returning device; the bottom of the hearth is provided with a raw coal port; the bottom of the side wall of the hearth is provided with a secondary air opening and the bottom of the hearth is provided with a primary air opening; the bottom of the material returning device is provided with a material returning air opening; and the bottom of the hearth is provided with a slag port. Medium and high multiplying power circulation fluidization technology is adopted, and the coal types have high adaptability and combustion efficiency; oxygen-poor combustion is performed in a dense phase region on the lower part of a combustion chamber so as to form a reducing atmosphere; oxygen-enriched combustion is performed on the upper part of the secondary air port so as to form an oxidizing atmosphere; and ideal combustion efficiency can be realized and the emission of sulfur and NOX can be greatly reduced.
