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： The present disclosure deals with the regulation of fluid flows in the presence of turbulence. The teachings thereof may be embodied in regulating a fluid in a combustion device. For example, a method for regulating a burner device may include: requesting a flow of a fluid through a feed duct; assigning the requested flow to a setting of a first actuator; transmitting a first signal to set the first actuator; generating a mass flow signal representing an actual flow through the side duct; correlating the second signal to an actual value of the flow through the side duct; correlating the requested flow through the feed duct to a required flow through the side duct; generating a regulation signal with the regulator for the second actuator as a function of the actual value of the flow through the side duct and the requested value of the flow through the side duct; and transmitting the generated regulation signal to the second actuator.

摘要： Systems and methods are provided for controlling temperature in a glass forehearth. In one implementation, a system includes at least one burner disposed in said forehearth, a manifold coupled to said burner, a combustion fuel supply coupled to said burner, a combustion air blower for delivering ambient air under pressure to said manifold, and a controller coupled to said burner for controlling operation of said burner. The system may include a temperature sensor operatively coupled downstream of the blower for providing to the controller a temperature signal indicative of temperature of air delivered to the manifold by the blower. The controller may be responsive to the temperature signal for controlling operation of the burner as a function of current temperature of air fed to the manifold. Operation of the burner may also be controlled as a function of an average air temperature over a preceding time duration.

摘要： A control apparatus for a gas-fired heating appliance having a burner is provided for sensing burner flame instability. The apparatus includes a sensor for sensing a flame and providing an output of a flame current signal, and a controller in communication with the sensor for sensing flame current. The controller is configured to receive the flame current signal and to detect the occurrence of a flame instability condition. The controller detects flame instability from flame current signal data that is measured and Fourier transformed into a frequency spectrum which changes from a stable to instable spectrum when flame instability is caused by an inadequate air-to-fuel ratio. The controller is configured to respond to flame instability by generating an output signal to increase the speed of a combustion air blower that supplies air to the burner, to thereby increase the air flow relative to fuel flow until normal combustion is attained.

摘要： A furnace control system for controlling a gas-fired induced-draft furnace having a variable speed inducer blower. A control apparatus, responsive to a signal corresponding to the magnitude of a pressure difference between an inlet and outlet of the combustion chamber, controls blower motor speed to maintain the pressure difference at a predetermined magnitude corresponding to a selected gas flow rate. Inducer blower motor speed is varied directly and precisely to maintain an optimal pressure drop across the combustion chamber. The control system can be used in multi-stage and modulating furnace systems and in furnace systems utilizing pressure- assist modulating gas values.

摘要： An apparatus for generating and collecting particulate matter derived from combusting a carbon-containing fuel in oxidising gas comprises a fuel burner with a nozzle housed in a container. The container has a gas inlet and a gas outlet; the gas outlet connects with a conduit for transporting the gas to atmosphere which is associated with means for forcing gas to flow from the gas inlet via the container and the conduit to atmosphere. Located within the conduit is a station for collecting particulate matter from gas flowing through the conduit. The gas flow-forcing means is controlled in response to a detected gas flow rate at the gas inlet to ensure the rate of gas flow at the gas inlet is maintained at a desired rate, thereby to promote particulate matter formation. A method for collecting particulate matter derived from combusting carbon-containing fuel is also disclosed.
