METHOD AND SYSTEM FOR DETERMINING MASS TEMPERATURE IN A HOSTILE ENVIRONMENT

摘要

PATENT APPLICATION OF RICHARD H. KRAUSE THOMAS J. PFEIFFER VINCENT V. HORVATH FOR METHOD AND SYSTEM FOR DETERMINING MASS TEMPERATURE IN A HOSTILE ENVIRONMENT 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 a 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 aquiring 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. Each subsystem logs both coke level data and coke vertical and horizontal temperature profile data and alarm messages. Tabular printouts of temperature and diagnostic data are provided by both the portable terminal printer in the onboard subsystem and the base computer printers. Graphical displays are also provided by the base computer system of coke level, temperature and summary data, oven push schedules and/or self-diagnostic messages of various process and measurement operations.
