Abstract

The experimental procedure comprised four stages outlined below: Assessing certain physical properties of corn stalks - Chopped corn stalks utilizing a hammer mill at a cutting speed of 1600 rpm and three distinct moisture contents (8%, 9%, 10%). - Material was processed in a screw press machine at a pressure of 100 MPa and a temperature of 170-175ºC, with three moisture contents for corn stalks (8%, 9%, 10%). - Assessing various quality attributes of pressed briquettes, including durability, hardness, compression ratio, bulk density, calorific value, and resiliency.
The results obtained from this study can be summarized as the following: (Physical properties for corn stalks - Measuring some quality properties of corn stalks briquettes produced by screw press).
The results obtained during the experiment showed that the best moisture content to start the corn stalks pressing process under a temperature of 175^○C is 8%, as found that the resulting briquettes are more cohesive and when burned, they have a lower emission rate of CO₂ (1.1%), CO (0.0146%) and SO₂ (0.000%), and thus this treatment is the best environmentally friendly treatment, and it also gave the highest calorific value (16.80 MJ/kg).
