Qx L-Series New High-Capacity Compound Circulating Water-Tube Hot Water Boiler

1The front and back water cooled wars and arc tubes all adopt backwater forced injection equipment,so as to guarantee that water speed in heated pipes of these circulation loops can far exceed the minimum security speed during operation ,thus ensuring safety of water circulation during power outage.
2The side water wall tube and convention bank adopt forced circulation ,so as to make sure that water speed in this series of tube scan far exceed the minimum security speed ,wash away sediment at the lower part of the cylinder body ,and completely eliminate the possibility of water wall tube explosion .if water outage happens during running ,the side water wall tube and convention bank will automatically form natural circulating loop, thus fully ensuring operation safety of the side water wall tube and convention bank.
3The boiler furnace is covered in the inner side of convention heating surface ,as flue gas temperature in flue pipes on two sides and forepart convention heating surface is low.so the heat preservation effect is remarkable and skinning radiation loss is now.
4The front and back arches adopt diversion design ,the back arch is low ,long and of high coverage ,combustion of high temperature flue gas can sweep past coals afire and rush to the front arch with the aid of the back arch ,coal newly added into types ,complete combustion and high boiler heat efficiency.
5the boiler body is of frame structured ,and adopts parallel composite structure of the side water wall tube and convention bank as supporting component of the entire boiler .under operative mode ,heating surface of the boiler can carry out thermal expansion upward freely ,which eliminates thermal stress and makes the structure stable and reliable ;
6Convention heating surface of the boiler all adopt flue gas cross-flow scrubbing mode,which not only leads to high heat transfer efficiency of heating surface large output and fast speed in temperature rise ,but can also reasonably devise and fix up soot door and access door in flues of convention heating surface ,which is quite convenience for operation management and overhauling also extremely import for operating high-capacity hot water boiler with great amplitude of running load variation.
7Compared with boilers with other furnace profiles and same capacity ,due to the use of water-tube heating surface and lower supporting entity structure ,the new high-capacity compound circulating water-tube hot water boiler is about 15%-35%than others, and the higher the capacity is ,the larger the amplitude of height reduction will be which will greatly reduce cine-construction cost of boiler room and lower investment of users;
8The adoption of inertia isolation technique of smoke and dust within furnace renders the initial dust emission concentration of the boiler greatly lower than the requirements in GB13271emission standard of air pollutants for boilers .
Note;It is preferable to adopt high-temperature running and to-eradicate long-term running with outlet temperature of 70ºC
