The Differences Between Water Tube Boilers and Fire Tube

A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler. Water tube boilers are used more for industrial
