Title:
BOILER COAL SAVING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/015466
Kind Code:
A1
Abstract:
A boiler coal saving control method, comprising a linear relation model creating step, an optimization target determination step, and a machine learning step; the linear relation model creating step is used for creating a multi-grade model grading mechanism and creating linear relation models accordingly, so as to fill an empty set in a data set; the multi-grade model grading mechanism comprises: taking three characteristic values, i.e. the boiler load, the coal quality, and the ambient temperature in boiler base conditions as grading indexes, so as to generate primary grading; and performing secondary grading on the basis of the boiler load; the optimization target determination step is used for determining a target to be optimized in a boiler, including a combustion efficiency of a boiler and the control of nitrate concentration in flue gas; the machine learning step is used for performing machine learning according to a data source, and comprising a model numbering sub-step, an ontology determination sub-step, and a target optimization sub-step. Said control method neither needs to change a combustion structure and principle of a boiler, nor needs to add additional detection nodes, but provides a safe and reasonable operation recommendation by means of a machine learning method, improving the combustion efficiency of a boiler, saving coal and improving efficiency.
