Furnace

A furnace is an enclosed structure in which fuel is burned to create heat, typically used for industrial processes like smelting metals, glassmaking, or heating buildings. Modern furnaces often employ electricity or gas as fuel sources, and are designed to efficiently control temperature and air flow for specific purposes. Their core function involves generating and containing extreme heat to achieve desired results through thermal processing.

Furnace meaning with examples

• The blacksmith stoked the coal furnace, eagerly anticipating the molten metal needed to forge the new plow. The intense heat inside, built up over hours, allowed the steel to soften and become malleable, perfect for shaping. It was essential to the trade and vital for making tools.
• During the winter months, the central heating furnace in the basement roared to life each morning, warming the entire house. The gas furnace provided comfortable living, keeping the house warm during long nights.
• Scientists used a high-temperature furnace to test the heat resistance of new ceramic materials used for aircraft. Monitoring the furnace allowed them to collect data and determine if the new parts were safe.
• The smelter's furnace, a colossal, brick-lined structure, played a crucial role in the gold extraction from the ore. The intense heat was necessary to separate the precious metal, thus increasing its value.
