Alumina steam production and elimination interlocking method

The invention relates to an alumina steam production and elimination interlocking method, and solves the problems of massive steam waste, low pulverized coal combustion efficiency and high ton alumina production cost caused by lack of relevance of steam production and consumption data of each procedure in the existing alumina production process. According to the alumina steam production and elimination interlocking method, through interlocking of the steam consumption in technical sections such as high-pressure dissolution, pre-desilicication, mother liquor evaporation, desulfurization, boiler self-use, coal gasification and the like in the alumina production process and the boiler steam yield, interlocking of boiler steam production and crude fuel and interlocking of crude fuel and a power device, an online production and elimination interlocking relation of alumina production is established, so that the coal consumption in the boiler combustion process and the steam demand in the operation process are reduc
