Boiler Island Equipment: Beyond the Stea

The most common economizer design is the bare tube in-line type, as shown in Figure 1. The tubes are horizontally placed in-line, or right on top of each other, to allow the flue gas to flow freely down around the tubes. The use of economizers with steam-generating boilers goes back to the earliest boiler designs.

Steam Boilers - Performance Heating, L

The cooler water travels through the down-comers to the mud drum, where the water will be reheated. Fire tube boilers are designed with gases traveling through numerous tubes immersed in water. The hot gases heat up the tubes which heat up the water, in turn generating steam. Generally, fire tube boilers cannot produce steam at very high pressures.
