Waterwall

Definition

A Waterwall is the furnace wall of a boiler where initial heat is absorbed from a coal fire. The wall is made up of tubes equally spaced with membranes in between.

Purpose

The purpose of a waterwall is to absorb heat from the combustion process in a boiler, transferring it to water or steam within the tubes. This is crucial for efficient boiler operation and heat exchange.

Examples of Use

• Power Plants: Waterwalls in coal-fired boilers absorb heat and generate steam for electricity production.
• Industrial Boilers: Used in manufacturing processes requiring large amounts of steam.
• Heating Systems: Central heating systems in large buildings or complexes use waterwalls in their boilers.

Related Terms

• Boiler: A vessel in which water is heated to produce steam or hot water.
• Heat Exchanger: A system used to transfer heat between two or more fluids.
• Combustion Chamber: The area in a boiler where fuel is burned to generate heat.

Notes

Waterwalls are critical components of boiler systems, ensuring efficient heat transfer and helping to maintain the desired temperature and pressure within the system.
