TEST REPORT FOR HY-C COMPANY, LLC Report No.: 104415176MID-002AR2 Date: 11/09/21
The total heat output during the burn shall be calculated as the sum of all the heat outputs over each time interval, as follows:
E d = ∑ (E t ) for t = t 0 to t final
Where: E d
= heat output over a burn, kJ/h (Btu/h)
E t
= heat output during each time interval, kJ/h (Btu/h)
The efficiency shall be calculated as the total heat output divided by the total energy input, expressed as a percentage as follows:
Efficiency, % = 100 × E d /I
Where: E d
= total heat output of the appliance over the test period, kJ/kg
I = input energy (fuel calorific value as-fired times weight of fuel charge), kJ/kg (Btu/lb) SECTION 9 TEST SPECIMEN DESCRIPTION The model SF1000E Solid Fuel Air Furnace is constructed of sheet steel. The outer dimensions are 50.5-inches deep, 42-inches high, and 25.5-inches wide. The unit has a fueling door located on the front. SECTION 10 TEST RESULTS DESCRIPTION OF TEST RUNS: RUN #1 (9/16/20): The furnace was set to draw a category 4 output rate. The test load weighed 30.61 lb. and utilized a 7.5 lb. coal bed. The average Btu/hr. output was 46,435. Burn time was 2.93 hours. The kg/hr. burn rate was 3.94. RUN #2 (9/17/20): The furnace was set to draw a category 2 output rate. The test load weighed 35.58 lb. and utilized a 6.6 lb. coal bed. The average Btu/hr. output was 21,540. Burn time was 5.82 hours. The kg/hr. burn rate was 2.31. RUN #3 (9/18/20): The furnace was set to draw a category 1 output rate. The test load weighed 37.19 lb. and utilized a 5.3 lb. coal bed. The average Btu/hr. output was 15,727. Burn time was 6.57 hours. The kg/hr. burn rate was 2.11.
