Problems solved by technology

In the past, the coal bunker emptying time could only be estimated from the coal bunker emptying curve, but when the coal supply changes, the curve becomes no longer instructive
Therefore, it is difficult to accurately calculate the amount of coal stored in the coal bunker

Embodiment Construction

[0019] Such as figure 1 As shown, the real-time measurement and calculation method of the coal volume of the coal bunker provided by the present invention calculates the volume of the coal bunker through the coal level of the coal bunker, and then calculates the coal storage volume of the coal bunker according to the volume of the coal bunker and the bulk density of the coal.

[0020] Such as figure 2 As shown, each coal bunker is arranged as a top cylinder 101 from top to bottom, an upper cone section 102 with a first inclination angle, a middle cone section 103 with a second inclination angle, and a lower cone with a third inclination angle body segment 104 . The inclination angle of each cone section is the angle between the side wall of the cone section and the horizontal plane. In this example, the first inclination angle a1 is 60°, the second inclination angle a2 is 65°, and the third inclination angle a3 is 76.88 °.

[0021] Extend the side walls of each cone segmen...

Abstract

The invention relates to a coal bunker amount real-time measuring and calculating method. One coal bunker is formed from top to bottom by a top cylinder, an upper conical section having a first inclination angle, a middle conical section having a second inclination angle and a lower conical section having a third inclination angle, wherein a relative upper virtual conical body is formed under the upper conical section; a relative middle virtual conical body is formed under the middle conical section; a relative lower part virtual conical body is formed under the lower conical section; height value of a coal bunker position can be input or measured; according to the coal bunker position, the coal bunker volume can be calculated; and coal bunker storage amount can be calculated according to the coal bunker volume and coal piling density. The coal bunker amount real-time measuring and calculating method has high calculating efficiency and coal charging accuracy can be improved.

Description

technical field [0001] The invention relates to a method for real-time measurement and calculation of coal quantity in a coal bunker. Background technique [0002] During the shutdown and operation of the unit, it is necessary to accurately monitor the amount of coal in the coal bunker. According to the shutdown time and method, control the coal level of each raw coal bunker to an appropriate position. If the unit is shut down for major repairs, the raw coal in the coal bunker should be emptied to prevent spontaneous combustion of coal stored in the bunker for a long time or to facilitate maintenance and inspection. During the shutdown process, due to the consideration of the steam temperature drop rate and load drop rate, the control of the coal volume in the coal bunker needs to be extremely precise, so as to accurately estimate the shutdown and empty bunker time. Generally, the coal level monitoring of the coal bunker must be given, and the raw coal bunker is generally i...
