Abstract

The invention relates to an online coal quality database system for digital power plant construction, and relates to the field of digital power plant construction. The system is characterized by comprising the following steps: establishing an in-plant coal quality database; establishing an off-plant coal quality database; establishing a coal quality anomaly feature library; optimizing a blending model; optimizing a coal blending mode; evaluating combustion and blending combustion of coal as fired; detecting the carbon content; establishing a distributed database platform; establishing a coal quality analysis algorithm platform; and analyzing the platform. The high-performance parallel time sequence database system can complete high-performance calculation, access multiple data sources, clean, extract and aggregate data and store the data on the basis of a time sequence, and has a data dynamic updating mechanism. Through a data mining technology, a large amount of historical coal quality data is applied to correlation analysis of boiler combustion effects, and a boiler combustion guidance target is achieved by providing combustion evaluation data.

Description

technical field [0001] The present invention relates to a digital power plant construction system, more specifically, to an online coal quality database system for digital power plant construction. Background technique [0002] Changes in coal suppliers and fluctuations in coal quality have brought difficulties to the safe and economical operation of power plants, and different coal qualities will have different effects on combustion. If the volatile content is too high, it will easily cause the nozzle of the burner to burn out; if it is too low, it will be difficult for the pulverized coal to ignite, the furnace will not burn stably, or even a flameout accident; The wear and tear of the heating surface of the boiler is intensified, the air preheater is blocked with ash, and the furnace is slagging and other equipment damages. Contents of the invention [0003] In order to overcome the shortcomings of the above technical problems, the present invention provides an online ...
