| description | The invention discloses a coal-fired boiler variable-load operation device and a control strategy, and belongs to the technical field of direct-current combustors. The method aims at effectively improving the variable load operation speed and stability of the coal-fired boiler. Comprising the following steps: S1, storing a strategy in a central processor; s2, a variable load instruction is issued to a central processor, and the variable load instruction, the current boiler load, the secondary air volume, the primary air volume, the feed water flow, the coal feed amount and the on-off condition of a combustor are received through a receiving device and transmitted to the central processor; s3, the central processor analyzes and outputs a proper control function to the control device; and S4, the control device controls the change of the secondary air volume, the primary air volume, the feed water flow, the coal feed amount and a burner switch, and variable-load operation of the boiler is achieved.
