TITLE(s): FURNACE-COMBUSTION ANALYST (glass mfg.) alternate titles: combustion analyst

Tests temperature of glass melting furnaces and regulates gas and air supply to maintain specified temperature, using any of following methods: (1) Measures temperature of furnace sections, using optical pyrometer. Sights through opening of pyrometer into furnace opening and turns sleeve dial on pyrometer until color of wire filament matches luminosity of flames. Reads dial indicator to obtain millivolt reading and compares reading with temperature chart to determine if temperature is in accordance with specifications. Turns valves to adjust gas-to-air ratio and increase or decrease temperature within refractory. (2) Computes and plots averages of glass temperatures on graph paper from temperature charts, using pencil and template to draw lines and circles. Interprets graph to determine need for temperature adjustment. Turns valve to increase or decrease air and gas supply into burners. (3) Tests gas-to-air ratio of burned atmosphere, using gas analyzer. Inserts hose of gas analyzer into furnace and starts suction pump to withdraw sample of burned atmosphere. Observes dial indicator on analyzer to determine if gas-to-air ratio is in accordance with specifications. Turns valve to adjust gas-to-air ratio and control heat of furnace. Records tests, temperatures, and adjustments in log.
