SZL series steam boiler coal fired boilers Introduction
SZL water tube quickly installed (assembled) steam boiler has 2 vertical steam drums, and the innovative horizontal cyclone-fired combustion chamber, which could effectively enhance the thermal efficiency and reduce the flue gas emission concentration. The flue gas emission concentration is lower than 100 mm/nm3, the flue gas blackness is lower than Ringeman level 1 .which enables the boiler to be used in the first-class environment protected area. The boiler installs one cast iron economizer at its back body, the grate applies the chamber-separated ventilation structure, which is easy to adjust. The separate-layer coal supply device could be chosen according to the customer requirement. Advantages of such boiler are strong power，high thermal efficiency，110% overload capability, compactly designed f small floor area. Customers appreciate its safely operated, investment conserved, and broadly fuel adapted.
Our oil/gas fired boilers can be divided into DHS series angle tube boiler,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.
The three series are designed with large furnaces, the thermal efficiency is over 98%, and the NOx emissions are as low as 30mg/Nm3. The front and rear smoke boxes are all equipped with a unique sealing structure to ensure that the smoke box does not leak smoke. At the same time, it has the characteristics of fully automatic and safe operation.
