Method and device for determining efficiency of gas-fired boiler

Abstract

The invention discloses a method and device for determining the efficiency of a gas-fired boiler. The method comprises the steps that S1,obtaining operating parameters of the boiler under different loads; s2, determining input and output parameters of the artificial neural network; s3, carrying out normalization processing; s4, determining a to-be-trained artificial neural network; s5, selecting apreset number of operating parameters from the operating parameters corresponding to each load as training samples, and taking the rest operating parameters as test samples; s6, training the to-be-trained artificial neural network by using the training sample to obtain a simulation prediction model; and S7, substituting the test sample into the simulation prediction model to obtain a simulation test value, judging whether the difference between the simulation test value and an actual test value is within a preset allowable range or not, if yes, determining the simulation prediction model as agas boiler efficiency model, and otherwise, executing S5. According to the method, the boiler combustion efficiency model is established through the artificial neural network, so that a basis is provided for optimization and improvement of the combustion efficiency of the gas-fired boiler.
