Physical testing of fuel briquettes

Evaluation of some optimum moisture and binder conditions for coal fines briquetting

“…According to Richards (1990), the most important physical properties of briquettes are resistance to crushing, impact, abrasion, and water penetration. These properties are all heavily dependent on the development of strong and durable bonds between particles during the agglomeration stage.…”

“…Four laboratory tests are recommended to monitor the physical strength properties of briquetted fuels either during process development or commercial production. These are a drop shatter test, a crushing resistance test, a tumbler abrasion test, and an immersion water resistance test (Richards, 1990).…”

“…According to Richards (1990), 'Impact resistance testing is considered to be the best general diagnostic of briquette strength'. …”

Synthesis on research results of FGD gypsum briquetting

“…The speed rate of the upper plate was 0,001 m/s. The test for compressive strength, the crushing load (in N) was measured on 10 briquettes from each batch and the average value converted to compressive strength (in MPa) according equation [5,6] …”
