With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.Get Price
Boiler water oxygen scavengers do just that; they are products that can be added to the boiler water that help to remove oxygen and so reduce the problems associated with corrosion. Oxygen scavengers There are several types of oxygen scavenger: organic and inorganic, the difference being that inorganic products add dissolved solids to the water.Get Price
