In the incineration sequence, which step directly precedes drying and ignition combustion?

• A. Dumping Platform
• B. Storage
• C. Charging Hopper
• D. Gas Cooling

Answer: (C)

In the incineration sequence, the step that immediately leads into drying and ignition is the feeding stage where waste is moved from storage into the furnace in a controlled manner. The charging hopper sits between storage and the combustion chamber, serving as the metered feeder that delivers waste into the incinerator. This control is essential because drying and ignition happen once the waste is inside the furnace and exposed to heat and air; a steady, regulated feed ensures the material dries properly and ignites reliably.

Dumping platform is the initial handoff where waste is unloaded, and storage is simply holding waste before it’s fed. Gas cooling occurs after combustion, in the exhaust treatment part of the system, so it cannot precede drying and ignition.
