摘要： A system and method for calibrating flame current in a furnace is disclosed. The method includes initiating combustion within a combustion chamber by allowing flow of the fuel mixture to the combustion chamber; receiving, from a sensor, signals indicative of a flow rate of the air to the combustion chamber; receiving, from a flame rod sensor, signals indicative of a flame current of the combustion chamber; varying a flow rate of the air to the combustion chamber; receiving, from the flame rod sensor, responsive to varying flow rate of the air to the combustion chamber, signals indicative of a change in the flame current of the combustion chamber; and determining, based on varying flow rate of the air to the combustion chamber, and the change in flame current of the combustion chamber, a correlation between the flow rate of the air, and the flame current of the combustion chamber.

摘要： Various embodiments include a method for estimating a flow value for fuels of different compositions supplied to a combustion device using a mass flow sensor. An example method includes: recording a first temperature of the fuel using a first resistor element; determining a compensable value with a heat output signal of a heating element; and estimating a flow value for the fuel supply by compensation of the value compensable as a function of the first temperature and/or as a function of the fuel composition and/or as a function of the fuel gas composition on the basis of at least one saved mapping rule dependent on the first temperature and/or on the fuel composition and/or on the fuel gas composition and on the basis of a calibration characteristic curve saved for a reference gas.

摘要： A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

摘要： The present disclosure provides a tuning system for tuning the operation of a gas turbine. The system comprises operational turbine controls for controlling operational control elements of the turbine, including at least one of turbine fuel distribution or the fuel temperature. The system also has a tuning controller communicating with the turbine controls. The tuning controller is configured to tune the operation of the turbine in accordance with the following steps: receiving operational data about the turbine, providing a hierarchy of tuning issues, determining whether sensed operational data is within predetermined operational limits and producing one or more indicators. If the operational data is not within predetermined operational limits, the tuning controller will rank the one or more indicators to determine dominant tuning concern, and tune the operation of the turbine based on dominant tuning concern. Also provided herein are a method and computer readable medium for tuning.

摘要： Herein provided are methods and systems for detecting failure of a sensor in a control system for a gas turbine engine. A signal is received from the sensor. A high-pass filter is applied to the signal to produce a high-frequency component signal. A rate of occurrence of signal spikes in the high-frequency component signal is determined. The high-frequency component signal is compared to a component signal threshold which is based on at least one known healthy component signal and at least one faulty component signal. The presence of intermittent open circuits caused by the sensor is detected based on the comparing and on the rate of occurrence of signal spikes.

摘要： This paper presents a model predictive control (MPC) strategy for BioGrate boiler, compensating the main disturbances caused by variations in fuel quality such as the moisture content of fuel, and variations in fuel flow. The MPC utilizes models, the fuel moisture soft-sensor to estimate water evaporation, and the fuel flow calculations to estimate the thermal decomposition of dry fuel, to handle these variations, the inherent large time constants, and long time delays of the boiler. The MPC strategy is compared with the method currently used in the BioPower 5 CHP plant. Finally, the results are presented, analyzed and discussed.
