Water Tube Boiler











he industrial watertube boiler typically produces steam or hot water primarily for industrial process applications and is used less frequently for heating applications. In the watertube design, tubes contain steam and/or water and the products of combustion pass around the tubes. Typically, watertube designs consist of multiple drums. A steam drum (upper) and mud drums (lower) are connected by the tubes, which form both the convection section and the furnace area. Packaged industrial watertube boilers are typically rated in pounds of steam per hour output at operating conditions and range from 10,000 to 150,000 lbs/hr. Industrial watertube boilers are noted for their fast steaming capability and high steam quality. Steam is generated very rapidly because of the relatively low water content, thus allowing quick response to changing load demands.

The industrial watertube boiler design makes it capable of generating either saturated or superheated steam. When applications dictate superheated steam, large or fluctuating steam loads, high pressures or high steam quality, an industrial watertube boiler should be considered.....
