The traditional method for determining the optimal coal blending ratio is generally determined through experiments. The test method comprises the steps of measuring related parameters to calculate the boiler efficiency of the unit through the co-combustion ratio of different coals under a certain stable load condition, and determining the optimal coal blending ratio according to the maximum target value of the boiler efficiency. The test methods only consider the influence of the boiler efficiency, but do not consider the change of the plant power rate of the boiler equipment caused by different blending combustion ratios, and the optimal blending combustion ratio of the coal cannot be objectively evaluated.
And the lowest power supply coal consumption is taken as a target value, the efficiency of the steam turbine needs to be considered, so that the determination of the optimal coal blending proportion is complex, and the analysis result of the optimal coal blending proportion is influenced by the efficiency of the steam turbine, the heat supply of a unit and other factors.
Meanwhile, due to the difference of fuel prices, the blending proportion with the lowest coal consumption is not the optimal blending proportion with the lowest cost, and the change of the fuel prices brings the corresponding change of the optimal blending proportion.
Therefore, a simple and accurate calculation method is needed to determine the optimal blending ratio of the coal.
