Boiler Drum Level Measurement

Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. 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.

Damage to the steam drum, the boiler, and the turbine can result from inaccurate drum level control. If the drum level falls below set-point, there is a risk of the boiler running dry. If the level is higher than set-point, there is a risk that wet steam could carry over to the turbine, causing damage to the turbine blades.
