Water Tube Boiler Types

In general, the industrial boilers fall into two categories: watertube boiler and firetube boiler. The water tube boilers are very common in industrial application and utilities. The watertube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam.

Types of water tube boilers

SZS oil & gas D type boiler

SZL chain grate water tube boiler

Circulating fluidized bed boiler 

Waste Heat recovery boiler
