Longitudinal Drum Steam Boiler

Boilers : Types and Classification

Longitudinal drum boilers range from 2250 kg/h to 3600 kg/h. 2. Cross drum boiler. The drum in this type is placed in cross to the heat source. The temperature obtained in this type of arrangement is more uniform. When the steam loads are high the upper tubes can become dry which cause them to fail.
