Abstract

The invention relates to the technical field of boiler combustion, in particular to a circulating fluidized bed boiler operation optimization method and system. The method comprises the steps of obtaining an optimal curve set of the circulating fluidized bed boiler; the optimal curve set comprises a unit load-optimal lower bed pressure curve, a unit load-optimal economizer outlet flue gas oxygen content curve and a unit load-optimal primary air proportion curve; and controlling the operation of the circulating fluidized bed boiler according to the optimal curve set. The boiler efficiency can be improved, the power consumption of the fan motor can be reduced, and the power generation cost of the circulating fluidized bed boiler can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of boiler combustion, in particular to a method and system for optimizing the operation of a circulating fluidized bed boiler. Background technique [0002] The circulating fluidized bed boiler is a new type of boiler developed in the past 30 years. Compared with the traditional pulverized coal boiler, it has the characteristics of wide adaptability of coal types and low emission of combustion pollutants. Advantage. The circulating fluidized bed boiler has a large number of materials with a particle size of 100-300 μm placed at the bottom of the furnace. When the boiler is running, a high-pressure fan is used to blow and fluidize the material from the bottom of the material. In the axial distribution of the furnace, the furnace is divided into two regions: the lower dense phase zone and the upper dilute phase zone. In the dense phase zone, the high-temperature material and coal are blown by the high-speed ...
