Coal blending combustion method

The invention discloses a coal blending combustion method. The method comprises the following steps that a calculation scheme is carried out through a coal blending combustion model, the model is based on a power generation information automatic acquisition system, Data-link and Process book software are applied, mass unit data of a PI database is deeply developed and utilized, a coal price and a power supply coal consumption result are calculated, the optimal matched combustion scheme is selected through a matched combustion model, the matched combustion mode is determined according to the matched combustion model, and when the unit load changes, the matched combustion proportion of the economic coal type is changed through reverse grinding, so that the purpose of maximizing the matched combustion benefit is achieved. Through the effects of the coal blending combustion model and the automatic power generation acquisition system, it needs to be explained that the optimal blending combustion scheme can be rapi
