Vertical + level combustion tester - quality inspection report
"Vertical flame calibration:
1, place the burner vertical, ignite the gas purity is not less than 98% methane/gas) to adjust the needle valve that the flame is inner flame height of 40 + 2 ㎜, outer flame 125 plus or minus 10 ㎜, poor light observation, the flame is stable combustion for at least 5 min, the state"
2, adjust the burner flame tube mouth make copper block is situated on the upper part (55 + / - 1) ㎜, thermocouple suspension point to at least 75 ㎜ copper block bottom. Φ copper specifications: diameter (9.0 + / - 0.01 ㎜), bottom taper (45 + / - 0.5 °), the weight of the embedded thermocouple before for g (10.00 + 0.05)
3, determination of copper (initial temperature should be < rose from 100 + 2 ℃ to 50 ℃) the time needed for 700 + 3 ℃ (3 times) should be 54 + 2 s
