Abstract

The invention provides a multi-in and multi-out feeding system of a micro-coal atomization boiler stokehole. The system comprises multiple sets of stokehole coal feeding systems; each set of stokehole coal feeding system comprises a stokehole coal bin, a weighing coal feeder and a medium-speed mill connected in sequence; and the medium-speed mills in the multiple sets of stokehole coal feeding systems are respectively connected with multiple layers of combustors in a micro-coal atomization boiler through pipes. The system further comprises a coal powder mixing and distribution device; multiple feed ports of the coal powder mixing and distribution device are respectively connected with the medium-speed mills in the multiple sets of stokehole coal feeding systems; and multiple discharge ports of the coal powder mixing and distribution device are connected with the multiple layers of combustors in the micro-coal atomization boiler. The coal powder mixing and distribution device can directly feed powder to all layers of combustors, so that the stokehole pipe arrangement space is saved, the complicated degree of stokehole powder feeding pipes is greatly simplified, the equipment failure rate is reduced, and safe and stable operation of the micro-coal atomization boiler is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-efficiency pulverized coal furnace power generation, and more specifically, to a multi-inlet and multi-outlet feeding system in front of a micro-coal atomization boiler. Background technique [0002] Micro-coal atomization boiler is a kind of high-efficiency pulverized coal power boiler, which refers to a new type of coal-fired power pulverized coal boiler with "coal pulverized combustion technology" as the core. The fuel coal is ground to coal powder with a fineness of 200-250 mesh by a medium-speed mill or steel ball ink, and the impurities are fully removed during the grinding process. The particle size of the coal is very fine, easy to ignite, and the volatile content is high, which can improve the burnout rate. The combustion efficiency of the micro-coal atomization boiler can reach 96% to 98%; the boiler burns fully, and the incomplete combustion rate q4≤1%. The order of magnitude reduction of...
