Abstract

This chapter describes the analysis process of flue and fuel gases. For flue gas analysis, the apparatus normally used for the routine analysis of flue gas is the Orsat apparatus. The gases usually estimated are carbon dioxide, oxygen, and carbon monoxide. The apparatus consists essentially of a water-jacketed gas burette, connected by a common line of coarse capillary tube and tapped connections to three absorption pipettes, containing, respectively, solutions of potassium hydroxide, alkaline pyrogallol, and ammoniacal cuprous chloride. A leveling bottle is connected to the base of the gas burette to enable readings to be taken at constant pressure and for use in transferring gas to and from the absorption pipettes. Fuel gases are best analyzed in the Haldane or Bone and Wheeler apparatus.
