Anqing Petrochemical's coal distribution from "extensive" to "fine"

According to China Petrochemical News Network, Anqing Petrochemical Transportation Department has a large number of different types of coal coming into the plant, and the indicators of volatile content, calorific value and sulfur content are quite different.
No matter the volatile content and low calorific value of the coal coming into the plant, the data is the same as that of the coal entering the furnace.
The basic indicators are very different.
Uneven coal blending will directly cause fluctuations in the operation of the boiler of the thermoelectric department and even flameout.
Careful operation will increase the pass rate of coal allocation
.

Because there is no related equipment support in the coal blending process, the coal quality can only be estimated according to the parameters and operation mode of the coal stored at each coal source point, and then the coal quality can be checked by on-site personnel visually and hand-kneaded to check the coal quality.
Proportional control is difficult, and it is impossible to accurately and evenly blend coal into each coal bunker.
Coal blending has always been "extensive" management
.

In order to stabilize the coal distribution index and improve the quality of coal blending, combining thermal power production methods and boiler dry gas utilization, the Anqing Petrochemical Transportation Department started with strengthening the management of coal storage yards, mastering the quality of coal storage in the coal yard, and establishing coal storage in the coal yard.
The quality file card divides the railway coal shed and waterway coal yard into different areas.
The incoming coal is divided into different areas according to the source of the mine, the type of coal, and the quality characteristics.
All are unloaded from the source to the coal yard, reducing the direct supply rate and increasing the monitorability
.

At the same time, strengthen the management of coal blending in the furnace and formulate strict working procedures.
Before each batch of coal is blended into the furnace, a coal blending plan is formulated in advance, a coal blending record is established, and a coal blending file is formed
.

　　Ensure that the average value of the volatile component, the average value of the low calorific value, the average value of the volatile component and the average value of the low calorific value of the sample data before the LIMS information is released, and the average value of the volatile component and the average low calorific value of the coal mixed sample data are basically consistent with the predicted data calculated before the blending to ensure the thermal power boiler installation Safe and stable operation, realizing the gradual transformation of coal blending from "extensive" to "fine" management
