Steam Pressure Control Control Loop In Boiler

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.
