1.La-Mont boiler
2.Water tube boiler
Water tube blr –combustion products passes around de tube contain water
Tubes are interconnected for common header
So tat distbution ll be easy

3.Burner deponds upon de steam demand and boiler structure
Here circulatin of water is provided for large amt of stm production
Super htd steam
Forced water circulation

4.Semi flash type boiler
Small dia pipe
Closely spaced long tube
Emulstion of water and steam

5.smaller dia tubes offer a greater heat xcahnge
Heat evolved by burnin fuel to be more readily transmitted to the boiler water(for high evaporation rates)

6.Small amount of boiler reduces boiler wt along with tube thickness
Rapid circulation of water s reqd because high rate of heat transfer with thin tubes
Pure water circulation is required to avoid scale formation

7.scale formation leads to blockage and overhaeting
Thin metal gives little corr for the system.
