Abstract

The invention discloses a stratified combustion on-line optimization control system of boiler coal dust, comprising a gas sampling system and a data processing system, wherein the gas sampling system comprises a fume sampling probe and a fume component continuous monitoring system. The invention is characterized in that the fume sampling probe comprises a first fume sampling probe arranged at an opening of an A air preheater, a second fume sampling probe arranged at an opening of a B air preheater and a third fume sampling probe arranged in a boiler chamber; the data processing system comprises an industrial computer connected with the fume component continuous monitoring system and provided with a stratified combustion on-line optimization computation module; and DCS data of the industrial computer and a generator set are connected by a data collector. The invention utilizes a support vector machine theory by the method and the method to establish an on-line optimization model to carry out automatic training and optimization so as to obtain combustion optimization condition parameters to guide operation, thereby keeping high operation safety of the boiler, improving operation economical efficiency and reducing the emission concentration and totals of pollutants.

Description

technical field [0001] The invention relates to a boiler control method of a thermal power plant, in particular to an online optimization control system and an optimization method for boiler pulverized coal layered combustion, and belongs to the technical field of electric power and power engineering. Background technique [0002] The rapid growth of thermal power assembly capacity has resulted in a relative shortage of coal resources, complex coal sources for power plants, and large changes in coal quality, threatening the safety and economy of boiler operation. For this reason, layered combustion, a flexible and simple coal blending technology, can enhance the coupling between coal quality and furnace type. Layered combustion is based on the combustion mechanism to configure different coal qualities in different layer burners to adapt to the combustion characteristics of the boiler. [0003] The optimal working conditions of boiler operation are generally obtained through...
