The radiant waste boiler parameters, gasification index parameters, and gasification chamber parameters are used together as the target thermal information.

[0070] In this embodiment of the disclosure, the outlet temperature deviation value in the parameters of the radiant waste boiler can be compared with a predetermined temperature deviation threshold (usually 0.002 is selected in the experiment, and there is no limitation on this). If the outlet temperature deviation value is greater than the temperature deviation threshold, the actual average heat load of the radiant surface is used to replace the trial value of the radiant surface heat load in the initial data. Based on the replaced initial data, the parameters of the radiant waste boiler are iteratively calculated until the outlet temperature deviation value in the parameters of the radiant waste boiler is less than or equal to the temperature deviation threshold. The parameters of the radiant waste boiler, the gasification index parameters, and the gasification chamber parameters are used together as the target thermal information.

[0071] In this embodiment, initial data of the gasifier with radiant waste boiler is acquired.
