Page 7 of 16 RUN #2 (May 10, 2016). The furnace was set to a category 2 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 44.09 lbs. and utilized a 4.6 lb. coal bed. The average Btu/hr output was 29,008. Burn time was 6.75 hours. The kg/hr burn rate was 2.41. RUN #3 (May 11, 2016). The furnace was set to draw a category 4 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 38.15 lbs. and utilized a 7.6 lb. coal bed. The average Btu/hr output was 64,070. Burn time was 2.50 hours. The kg/hr burn rate was 5.63. RUN #4 (May 11, 2016). Test run #3 resulted in a slightly lower output than expected, so the client wanted to perform a second category 4 test. The furnace was set to draw a category 4 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 41.18 lbs. and utilized an 8.2 lb. coal bed. The average Btu/hr output was 70,603. Burn time was 2.57 hours. The kg/hr burn rate was 5.91. Test runs #3 and #4 will be averaged together. RUN #5 (May 12, 2016). The furnace was set to draw a category 1 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 44.03 lbs. and utilized a 4.5 lb. coal bed. The average Btu/hr output was 25,777. Burn time was 6.92 hours. The kg/hr burn rate was 2.33. This run has been determined to be invalid as the deviation between the two sample trains is greater than 7.5% and more than 0.50 g/kg. RUN #6 (June 22, 2016). The furnace was set to draw a category 1 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 44.17 lbs. and utilized a 5.9 lb. coal bed. The average Btu/hr output was 28,632. Burn time was 6.10 hours. The kg/hr burn rate was 2.59. This run has been determined to be invalid as the fan wheel on the combustion blower was found to be loose, which reduced the amount of combustion air to the firebox. RUN #7 (June 23, 2016). The furnace was set to draw a category 1 draw rate. The combustion blower was turned on to maintain the desired heat rate. The Test Load weighed 43.24 lbs. and utilized a 4.9 lb. coal bed. The average Btu/hr output was 25,586. Burn time was 6.90 hours. The kg/hr burn rate was 2.30.
