Dissipation rate test system and method suitable for large coal-fired power plant coal yard

Abstract

The invention provides a dissipation rate test system and method suitable for a large coal-fired power plant coal yard. The system comprises a coal pile sampling device, a test adjusting system and acoal dissipation rate model analysis system. The coal pile sampling device and the test adjusting system are arranged indoors, the coal pile sampling device is used for conveying coal and arranging the coal to form a coal pile, and sampling the coal samples of each layer of the coal pile; the test adjusting system is used for monitoring environment temperature and humidity data and gas concentration data, adjusting environment temperature and humidity and controlling ventilation, and simulating coal consumption conditions in different scenes; and the coal dissipation rate model analysis systemis used for acquiring and analyzing the coal sample test data, establishing a coal quality data model and a coal quality dissipation model, analyzing according to the coal quality data change beforeand after the test, and calculating the coal dissipation rate data. The coal yard dissipation rate can be accurately measured and calculated so that effective data support is provided for coal consumption and coal quality loss analysis work.

Description

technical field [0001] The invention relates to the technical field of coal yard management, in particular to a dissipation rate testing method and system suitable for coal yards of large-scale coal-fired power stations. Background technique [0002] In large coal-fired power plants, the coal cost accounts for more than 70% of the total cost. Therefore, the loss of coal quality and quantity has an important impact on the economic benefits of the power plant. During the storage process of coal yards in large coal-fired power stations, due to the influence of the external environment and its own characteristics, phenomena such as loss of coal volume, increase in moisture, decrease in calorific value, and spontaneous combustion of coal may occur. The important factors of coal quality and coal loss are also directly related to the production and operation benefits of thermal power plants. Therefore, it is the main work of the coal yard management of large coal-fired power stati...

AI Technical Summary

Problems solved by technology

Therefore, it is the main work of the coal yard management of large coal-fired power stations to do a good job in the analysis of coal consumption and coal quality loss, and to take good loss control measures to reduce the loss of coal consumption and coal quality. How to accurately calibrate the coal Field dissipation rate is an important issue to realize coal field management and control. At present, the acquisition of coal dissipation rate data still requires manual collection of coal quality and coal quantity change data under different environmental conditions and analysis and calculation, which takes a long time and is inefficient. low, room for improvement
