At present

there is a common phenomenon that the actual coal consumption is out of line with the designed coal type in power plants in China. There are more than ten kinds of coal from some power plants. Due to the different coal quality characteristics of different coal

which will inevitably affect the safe and economic operation of the boiler

it is necessary to mix and burn the actual coal to meet the stability of boiler combustion and reduce the cost of coal combustion. In determining the proportion of coal blending

if only manual calculation is too large

and it is difficult to achieve the optimal formula to minimize the cost of coal blending. Using computer to optimize the coal blending scheme can make full use of the advantages of fast computing speed of the computer

and find the optimal formula which can make the cost of coal blending of power plant the lowest and the best economic benefit in a short time. However

the coal handling mode in coal yard is manual operation

which has disadvantages of low efficiency

high labor intensity and bad working environment. It is of great significance for thermal power units to improve the efficiency and efficiency of fuel management by improving the automation and intelligence level of coal blending.
