DZL series fire tube boiler coal fired hot water boiler Introduction
The DZL series quickly installed hot water boiler is the most advanced water-fire tube boiler in China, which with high efficiency, small volume and long working life.The improved boiler takes use of the structure of wing type smoke duct, one-way threaded smoke tube, arch shaped tube plate, smoke and gas separation room and several other advanced technologies which have increased the water circulation speed and increased the safety factor.
This series boiler is well designed, compactly made up，quickly installed, monolayer, so that the civil engineering and the investment could be saved. These improvements has extends the boiler’s working life and make it the national energy saving product, which fills up the national margin.
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.
