A method of controlling defects in a glass product produced in a tin bath furnace includes measuring at least one parameter of an atmosphere associated with the tin bath furnace, wherein the parameter is selected from the group consisting of dew point and density, correlating the measured parameter with defects in the glass product, and controlling the measured parameter in a direction corresponding to decreased defects in the glass product by controlling a flow rate of a process gas relative to the furnace wherein the process gas includes one or more of hydrogen and nitrogen.

System and method for synchronized oxy-fuel boosting of a regenerative glass melting furnace

A remote burner monitoring system including one or more burners each including integrated sensors, a data collector corresponding to each of the burners for receiving and aggregating data from the sensors of the corresponding burner, and a local transmitter corresponding to each of the data collectors for transmitting the data, a data center configured and programmed to receive the data from the local transmitters corresponding to the one or more burners, and a server configured and programmed to store at least a portion of the data, to convert the data into a display format, and to provide connectivity to enable receipt and transmission of data and the display format via a network including at least one of a wired network, a cellular network, and a Wi-Fi network.

Remote burner monitoring system and method

An oxy-fuel burner () with monitoring including a fuel passage () terminating in a fuel nozzle (), a primary oxidant passage () terminating in an oxidant nozzle (), one or more sensors including a nozzle temperature sensor () for sensing at least one of an oxidant nozzle temperature and a fuel nozzle temperature, and a data processor () programmed to receive data from the sensors and to determine based on at least a portion of the received data the presence or absence of an abnormal burner condition including a potential partial obstruction of at least one of the primary oxidant passage () and the fuel passage () based on an increase or decrease in at least one of the oxidant nozzle temperature and the fuel nozzle temperature.

Burner with monitoring

An integrated sensor system for use in a furnace system including a furnace having at least one burner and two or more zones each differently affected by at least one furnace parameter regulating energy input into the furnace, including a first temperature sensor positioned to measure a first temperature in the furnace system, a second temperature sensor positioned to measure a second temperature in the furnace system; and a controller programmed to receive the first and second measured temperatures, and to adjust operation of a furnace system parameter based on a relationship between the first and second temperatures, thereby differentially regulating energy input into at least two of the zones of the furnace; wherein the relationship between the first and second temperatures is a function of one or more of a difference between the two temperatures, a ratio of the two temperatures, and a weighted average of the two temperatures.
