Method And System For Determining Mass Temperature In A Hostile Environment
US Patent:
4617638, Oct 14, 1986
Filed:
Jun 1, 1984
Appl. No.:
6/616520
Inventors:
Richard H. Krause - Lansdale PA
Thomas J. Pfeiffer - Bethlehem PA
Vincent V. Horvath - Bethlehem PA
Thomas J. Pfeiffer - Bethlehem PA
Vincent V. Horvath - Bethlehem PA
Assignee:
Bethlehem Steel Corporation - Bethlehem PA
International Classification:
H03K 1302, G01K 712
US Classification:
364557
Abstract:
Production-worthy method and system comprising two computer-based subsystems for determining temperature of an irradiant mass movable through process means in a hostile environment exemplified as coke guide and coke oven in a battery of ovens. System is usable in other industries such as at cement kilns and the like. First subsystem which is carried by a movable coke guide/door machine, includes one or more coke guide pyrometers arranged vertically, each with a sighting window monitor to detect optical errors, an onboard computerized and cooled electronics package for acquiring and processing temperature data and automatically detecting same for pyrometer drift and optical errors, and automatically correcting for these errors, and further including a plug-in portable terminal with a printer. The second subsystem stationed in a central office having a base computer package with various computation and storage capabilities including a CRT control terminal for operator interaction with the entire system, a line printer and a printer/plotter. Two-way data communication between the two subsystems is exemplified by a two-way radio link.
Pyrometer With Sighting Window Cleanliness Monitor
US Patent:
4435093, Mar 6, 1984
Filed:
Dec 8, 1981
Appl. No.:
6/328769
Inventors:
Richard H. Krause - Bethlehem PA
Thomas J. Pfeiffer - Bethlehem PA
Vincent V. Horvath - Bethlehem PA
Thomas J. Pfeiffer - Bethlehem PA
Vincent V. Horvath - Bethlehem PA
Assignee:
Bethlehem Steel Corporation - Bethlehem PA
International Classification:
G01J 504, G01J 526
US Classification:
374129
Abstract:
Coke guide and coke oven infrared pyrometer degrading is minimized to continuously permit better accuracy and reliability in hostile environment of coke mass and heat, dust and/or dirt present in many coke plant areas. These benefits are obtained using production-worthy pyrometer equipment having a purged pyrometer with any of three window cleanliness monitors to determine errors and automatically correcting for same through self-calibration.
