A total of 66 coke oven pushing plumes have been sampled using a specially designed mobile laboratory for characterizing the plume parameters of temperature, velocity, shape, and particulate emission. Temperatures were measured with two iron/constant and thermocouples at the end of the boom. A cup anemometer provided plume velocities and particulate samples were taken at a rate of approximately 43 scfm through 8 multiplied by 10 inch glass fiber filters.
