Abstract

A method for forecasting the temperature of a municipal solid waste incinerator relates to the technical field of key parameter forecasting in the municipal solid waste incineration process, and is used for forecasting the temperature of the garbage incinerator through input variables such as the speed of each section of fire grate, primary air flow, secondary air flow and fan pressure to guide field operators to timely and accurately judge the change trend of the furnace temperature. The method mainly comprises the following steps: (1) designing a heterogeneous feature set for establishing a furnace temperature forecasting model of the municipal solid waste incinerator; (2) data preprocessing; (3) dividing a training set of a fire grate temperature base model based on the heterogeneous feature set in the step (1); (4) determining a training set of a furnace temperature secondary learning model based on the step 1; (5) initializing parameters; (6) constructing a fire grate temperature base model and a furnace temperature secondary training model by adopting a regularization random configuration network algorithm; and (7) carrying out anti-standardization processing on the output of the furnace temperature secondary training model.

Description

technical field [0001] The invention relates to the technical field of forecasting key parameters in the municipal solid waste incineration process, more specifically, the invention relates to a method for forecasting the furnace temperature of a municipal solid waste incinerator. Background technique [0002] Waste incineration power generation technology can realize the harmlessness, reduction and recycling of municipal solid waste. Therefore, this technology has become one of the main ways for us to deal with municipal solid waste. It is worth noting that, on the one hand, due to the influence of the components of domestic waste in my country and the living habits of the people, it is difficult to accurately predict the temperature change during the incineration process. On the other hand, due to the strong hysteresis of the incineration process, it is difficult for on-site operators to judge the change trend of the furnace temperature in time, which may cause the furnace...
