Abstract
A hole through each of opposed walls of a combustion chamber of a glass melting apparatus and piping interconnect the chamber atmosphere to an oxygen analyzer. A sample of the chamber atmosphere is continuously moved through each of the holes and piping to the analyzer by the biasing action of the positive pressure differential between the chamber atmosphere and the ambient atmosphere.
Claims10
A method of monitoring atmosphere of a combustion chamber having a regenerator at each of opposed chamber walls with each regenerator communicating with chamber interior by at least one port, wherein pressure differential between chamber atmosphere and ambient atmosphere is positive, comprising the steps of:
- providing at least one access hole through each of the opposed chamber walls to move under the biasing force of the positive pressure differential a portion of the chamber atmosphere defined as a sample through each of the at least one access holes;
- determining oxygen content in the sample;
- and
- controlling oxygen content in the chamber atmosphere in response to said determining step.
A method of monitoring atmosphere of a combustion chamber having a regenerator at each of opposed chamber walls with each regenerator communicating with chamber interior by at least one port, wherein pressure differential between chamber atmosphere and ambient atmosphere is positive, comprising the steps of:
- providing at least one access hole through each of the opposed chamber walls to move under the biasing force of the positive pressure differential a portion of the chamber atmosphere defined as a sample through each of the at least one access holes;
- determining combustion products in the sample;
- and
- controlling combustion reactants in response to said determining step.
An apparatus for monitoring atmosphere of a furnace including a combustion chamber;
- regenerating means at each of a pair of opposed chamber walls;
- and at least one port at each of the opposed chamber walls to provide communication between the regenerating means and chamber interior wherein during furnace operation the pressure differential between the chamber atmosphere and ambient atmosphere is positive, comprising:
- means mounted at each of the opposed chamber walls for passing a portion of the chamber atmosphere defined as a sample from the chamber interior to the chamber exterior, said passing means includes the positive pressure differential and at least one hole through each of the opposed chamber walls;
- means for analyzing oxygen content in the sample;
- means for interconnecting said passing means and said analyzing means;
- and
- means fors controlling oxygen content in the chamber in response to said analyzing means.
An apparatus for monitoring atmosphere of a furnace including a combustion chamber;
- regenerating means at each of a pair of opposed chamber walls;
- and at least one port at each of the opposed chamber walls to provide communication between the regenerating means and chamber interior wherein during furnace operation the pressure differential between the chamber atmosphere and ambient atmosphere is positive, comprising:
- means mounted at each of opposed chamber walls for passing a portion of the chamber atmosphere defined as a sample from the chambers interior to the chamber exterior, said passing means includes the positive pressure differential and at least one hole through each of the opposed chamber walls;
- means for analyzing combustion products in the sample;
- means for interconnecting said passing means and said analyzing means;
- and
- means for controlling input of combustion reactants into the chamber in response to said analyzing means.
