Embodiment 1
[0025] This embodiment relates to a method for testing the calorific value of an oxygen bomb of corn stalks, the method comprising the following steps:
[0026] The first step is to select about 10 corn stalks from a certain corn field in Qili Village, Gangyan Town, Chongming County, Shanghai, using the scientific distribution method, peel off the stems and leaves, air-dry them, and then crush them through a 40-mesh sieve. The sieved corn stalks were dried at 45°C and 105°C, and the measured moisture contents of the corn stalks at 45°C and 105°C were 1.82% and 9.14% respectively. 0.4357%;
[0027] In the second step, use a small medicine spoon to add 1.235g of sample to the feeding hole of the tablet press to the uppermost edge of the feeding hole, then press the tablet, and use a clean white paper to pad the bottom of the feeding hole of the tablet press until the sample falls A cylindrical pressed sample is obtained;
[0028] The third step is to take out the sample that h...
Embodiment 2
[0031] This embodiment relates to a method for testing the calorific value of an oxygen bomb of corn stalks, the method comprising the following steps:
[0032] In the first step, about 10 corn stalks were selected from a certain corn field in Yichun City, Jiangxi Province by the scientific distribution method, the stems and leaves were peeled off, air-dried, and then crushed through a 60-mesh sieve; the crushed and sieved corn stalks were placed in Drying at 45°C and 105°C, the measured moisture content of corn stalks at 45°C and 105°C were 0.35% and 5.80% respectively; the H element content was 5.999%, and the S element content was 0.351%;
[0033] In the second step, use a small medicine spoon to add 0.883g of sample to the feeding hole of the tablet press to the uppermost edge of the feeding hole, then press the tablet, and use a clean white paper to pad the bottom of the feeding hole of the tablet press until the sample falls A cylindrical pressed sample is obtained;

Embodiment 3
[0037] This embodiment relates to a method for testing the calorific value of an oxygen bomb of corn stalks, the method comprising the following steps:
[0038] The first step is to select about 10 corn stalks in a certain corn field in Mengcheng County, Anhui Province by the scientific distribution method, peel off the stems and leaves, air-dry them, and then crush them through a 60-mesh sieve; the crushed and sieved corn stalks Dried at 45°C and 105°C, the measured moisture content of corn stalks at 45°C and 105°C were 0.02% and 3.63% respectively; the H element content was 6.334%, and the S element content was 0.417%;
[0039] In the second step, use a small medicine spoon to add 0.586g of the sample to the feeding hole of the tablet press to the uppermost edge of the feeding hole, then press the tablet, and use a clean white paper to pad the bottom of the feeding hole of the tablet press until the sample falls A cylindrical pressed sample is obtained;
[0040] The third s...
