Abstract:

Through calculating the calorific value loss in the storage period of lignite and the coal consumption loss in the mixed burning process, this paper converted the pros and cons after mixed burning of lignite into purchase cost of standard coal and compared it with common bituminous coal. After that, it analyzed the profit boundary point of mixed burning lignite from an economic point of view.
