Embodiment Construction

[0063] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0064] Technical scheme and process of the present invention are as follows:

[0065] 1. First establish a three-dimensional information model database of coal yard inventory, and use the data integration platform (which can be understood as an interface platform that supports data transfer between different systems) to obtain the quantity information of coal inventory from the coal yard inventory management system, which can be replaced by X, Quantity information should be subdivided into coal yard, segment number, level, etc., each with X n Instead; obtain the coal quality information of each coal type from the furnace coal quality inspection system, which includes calorific value Q, volatile content V, total moistu...

Abstract

The invention discloses a fire coal blending method of thermal power plants, which belongs to the technical field of thermal power generation and automation and includes: building a coal yard inventory three-dimensional information model database according to coal yard inventory information; building a boiler combustion standard information base according to requirements of each boiler on coal quality and boiler self influence factors; generating a constraint condition according to the boiler combustion standard information base and the coal yard inventory three-dimensional information model database, and building a fire coal economical objective function to obtain a fire coal blending model; and calculating all fire coal blending proportion schemes when the boilers consume standard coal with a set quantity according to the fire coal blending model, and selecting a scheme with topmost layer coal as the optimum scheme. The fire coal blending method is most economical, reduces unit energy consumption price and improves economic benefit of power generation enterprises under the premise of ensuring boiler safe combustion.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation and automation, and more specifically relates to a coal blending method for a thermal power plant. Background technique [0002] In my country's thermal power generation enterprises, fuel costs account for more than 70% of the entire generation cost of power generation enterprises. Therefore, how to reduce fuel costs is the main way for thermal power enterprises to improve economic efficiency. There are two main aspects to reducing fuel costs. One is to reduce the coal consumption of power generation, and the other is to reduce the price of incoming coal. The coal consumption of power generation can be reduced by improving the power generation efficiency of the unit. This involves a wide range of inputs and high costs, and the effect is also great. It is not very obvious; and reducing the price of coal into the furnace can be achieved by reducing the purchase price and coal blend...
