Summary
Weyerhaeuser Company contracted to modify the Oregon State University experimental combustor during June and July 1978 to facilitate the combustion testing proposed by the Test Plan (included as Appendix E) for August and September 1978. The tests were a joint effort between OSU and Weyerhaeuser, with the results being reported to OSU in an Interim Report to expedite transfer of data and a final report to complete the transfer of analytical results. The objectives of the tests are stated as follows: (1) determine how much the underfire air/fuel ratio and excess air levels interact with fuel fluctuations; (2) determine whether/how much fuel mixing, sizing, or segregation would affect furnace combustion efficiency and stack emissions; and (3) determine whether/how much fluctuations in fuel feed rate affect combustion efficiency and stack emissions. Preliminary results allow conclusions as follows: (1) The underfire air/fuel ratio and excess air levels interact with fuel fluctuations to a small degree. The effect of step-changes in combustion rate appear to be reduced by decreasing underfire air rate. Excess air appears to decrease the effects of step-changes in combustion rate as excess air is decreased. (2) Fuel mixing, sizing, or segregation could affect furnace combustion efficiency and stack emissions. Abrupt changes from wetter fuel to dryer fuel appears to generate increased particulate emissions. Increased emissions as high as 25 percent may last for several minutes during intense combustion of excess fuel banked for drying by the wetter fuel. However, increases in particulate emissions during fluctuations in fuel conditions tend to be nullified by decreases in emissions during opposing fluctuations.
