Furnace wall water cooling – eliminates refractory and related maintenance. Gas-tight setting membrane – inhibits dew-point sulfur corrosion and outages caused by gas leaks. Rugged steel-based frame – supports boiler and allows jacking and skidding. Outer lagging – galvanized, weather-tight for outdoor installations. Drum internals – ensure positive circulation, low …Get Price
Dec 21, 2020 · Water Tube Boiler Components. Here is a review of the water tube boiler parts and functions.. Boiler Shell: This shell is the external cylindrical part of a pressure container.

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.Get Price
