Operation and consumption optimization method based on boiler safety analysis

Abstract

The invention provides an operation and consumption optimization method based on boiler safety analysis. The operation and consumption optimization method is characterized by comprising the following steps that main parameter values in main load working conditions are used as target values of consumption calculation; data required by the consumption calculation in the operation of a boiler is collected, and the consumption calculation is performed in accordance with the target values, so as to obtain coal consumption indexes caused by the fact that main performance parameters deviate from the target values; a prediction model is established to predict optimized consumption; influencing factors which greatly influence parameter deviation are found out; parameters related to boiler safety are determined and monitored, if the parameters are within a safety range, a safety factor is 1, and the cost-benefit ratio of optimization operation is calculated; and when the cost-benefit ratio is less than 1, the optimization operation of the cost-benefit ratio is performed. The operation and consumption optimization method has the advantages that boiler safety analysis is introduced into the research of optimizing operation and consumption, economy and safety are combined together, and in consideration of actual conditions of the boiler, optimization operation which conforms to the actual conditions is adopted to the boiler.

Description

technical field [0001] Based on the research on the consumption difference of the boiler safety and optimal operation, on the basis of the unit consumption difference, the safety analysis is introduced into the research on the causes of the consumption difference. Through the safety analysis, the combination of the consumption difference, safety and optimal profit ratio is used as the optimization judgment Indexes, to obtain the real reasons that affect unit parameters and coal consumption and the effective optimization measures that can be taken, belong to the technical field of thermal power generation units. Background technique [0002] Affected by various factors, there is a gap between the operating parameters of the thermal power plant and the design parameters, which affects the thermal economy of the power plant. The one-sided pursuit of thermal economy challenges the safe operation of the unit and affects the stability of the unit operation. When configuring appro...

Problems solved by technology

[0004] The domestic power consumption optimization system does not take into account the safety analysis of the power plant, which makes the economic index of the power consumption target often out of touch with the safe operation of the power plant. In fact, the deviation between the operating parameters and the design value is not because the operators do not know, but is restricted for some reason
