Well balanced construction for maximum industrial capacity
The A-Type watertube steam boiler, with centered steam and two lower mud drums, offers a symmetrical and well balanced design. This configuration generates increased performance of up to 250,000 PPH.

The A-Type boiler design offers a large volume furnace ending on two convetion zones, one on each side of the furnace. Optional open bottom furnace is well suited for cogeneration and solid fuel firing.
