The report summarizes the second year's operation of EPA-owned mobile test units. Unit use divides into two principal areas: (1) three units (baghouse, electrostatic precipitator (ESP), and wet scrubber) are designed for use in the field to study the applicability of different methods for controlling fine particulate emitted from a wide variety of sources; and (2) a fourth unit (energy van) is designed to demonstrate the feasibility of unconventional energy supply systems to support residential and commercial buildings. Results from baghouse tests on a kraft mill lime recovery kiln indicate an overall, integrated collection efficiency of 99.98+ wt %. Based on collection efficiency alone, a high level of control can be afforded by a baghouse on lime kiln particulate emissions. However, based on projected operating problems due to high moisture content of the gas, baghouse control of a lime recovery kiln is not recommended. Mobile scrubber unit operation during the year was confined to startup field testing and correction of mechanical and operating difficulties. The ESP unit is still under construction. The newly acquired energy van has not yet undergone testing.
