Abstract: A method for combustion tuning, comprises collecting exhaust parameters indicating combustion status of a boiler by a sensor array; determining whether the exhaust parameters of the boiler match a preset optimization target; and optimizing combustion, if the exhaust parameters do not match the preset optimization target by selecting a model from a model repository based on a current boiler condition, wherein the model corresponds to a relationship between model input variables and the exhaust parameters; determining at least one optimized model input variable of the boiler for realizing the optimization target, based on the selected model; and adjusting actuators of the boiler according to the optimized model input variable.

Abstract: The present invention provides an elevating bed capable of detecting braking performance. The elevating bed comprises an elevating assembly, a driving motor connected to the elevating assembly and driving the elevating assembly to move, a brake device connected to the driving motor and a control module connected to the driving motor and controlling the driving motor to rotate, and connected to the brake device and controlling the brake device to be enabled or disabled; when the control module disables the brake device, the control module controls the driving motor to drive the elevating assembly to move for a first movement distance and calculates a first torque value of the driving motor; when the control module enables the brake device, the control module controls the driving motor to drive the elevating assembly to move for a second movement distance and calculates a second torque value of the driving motor, the control module determining whether the brake device is normal or abnormal according to a relationship between the first torque value and the second torque value.
