Etymology
炉 combines 火 (fire) with 户, which is a simplified form of 盧, likely contributing the sound and possibly the idea of a container. The modern form is a phono-semantic compound with a simplified phonetic.
Meaning mnemonic
The left side is fire 火, and the right side 户 looks like a door or enclosure. Picture a fire contained behind a door-like opening: a hearth or furnace.
Reading mnemonic
For ロ, imagine a low, roaring fire inside the hearth: low -> ロ, and the flames are contained within the furnace.
