Difficulty: Easy
Correct Answer: Yes
Explanation:
Introduction / Context:
Briquetting converts fine coal or coal dust into larger agglomerates for easier handling, transportation, and combustion. The definition focuses on forming under pressure, often with binders.
Given Data / Assumptions:
Concept / Approach:
Briquetted coal refers to densified, shaped products (briquettes) produced from fines. The essence is mechanical compaction (and sometimes thermal curing) with or without a binder to achieve strength and durability.
Step-by-Step Solution:
Identify raw material: coal fines unsuitable for direct use.Apply compaction/moulding under pressure (with/without binder).Product obtained: briquetted coal — easier to store, transport, and burn.Hence, the statement matches the standard definition.
Verification / Alternative check:
Industry practices (roller presses, piston presses) produce pillow or oval briquettes consistent with this definition.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing “briquettes” with “coke” (destructive distillation) or “pellets” from ore fines; processes and products are different.
Final Answer:
Yes
