4t Horizontal Coal Fired Water Tube Steam Boiler (DZL)

Technical Description:DZL series quick-installed steam boiler is a kind of horizontal,three returns, water-fire tube, chain grate boiler, using middle bituminous coal and anthracite,etc as fuel. The boiler with a single drum is placed horizontally.In the drum, we use threaded tubes to enlarge the heating surface. The drum and two-side water wall tubes compose radiation heating area.The celectric controller realizes the grate speed stepless change, the alarm system for the limit parameters and the interlock protection.
Advantages of DZL series water-fire tube steam boiler:1. Strong output and keep steadyAs adopting the threaded tubes and reasonable structure design, the boiler's actual output is generally more 10-15% than what the data plate says.Due to the exact tube size and reasonable fume speed,there is few ash and abrasion in the tubes.So the output is steady when the boiler works.2.Small dimension leading to a low investment to the boiler house3. No need special protection when power failure happens suddenly
4. High net efficiency
5. Fasting Heating-up
6.Lower dust consistence than state standardThe big firepot, new type boiler arch and dust separation turning room, all of the three, ensure the fuel is burned fully and the dust consistence is lower than state standard.7. Short installation time and low cost8.Strong water adaptabilityAs using new rising tubes in the structure, it raise the flow rate of rising water.That lead to the strong water turbulence at the bottom of the drum.So it can avoid much deposit and incrustant in a long time. Comparing to other boilers,the boiler's water adaptability is strong.Specifications& ParametersModelSZS4-1.25-Y(Q)ASZS6-1.25-Y(Q)ASZS8-1.25-Y(Q)ASZS10-1.25-Y(Q)ASZS10-1.25-Y(Q)DSZS15-1.25-Y(Q)ASZS20-1.25-Y(Q)ARated Evaporation Capacityt/h46810101520Rated Steam PressureMpa1.251.251.251.251.251.251.6Rated Steam Temperature°C194194194194194194204Rated Feeding Water Temperature°C105105105105105105105Heating AreaRadiation Aream 222.526293237.150.2472.1Convection Aream 274.7106138170114.5193.25261Economizerm 226.1639.4241.8452.3/52.3270Air Heaterm 235.79455157.68/65.65/Fume Temperature°C161160161163180153.45180Heat Efficiency (Gas-fired)%>90%Available Fuel/Light oil, Heavy oil, Nature gas, City gas, Liquefied gas, Coal gas/<1Overall SizeLengthmm8500900092001000074001150012900Widthmm3500400040004000500040004000Heightmm4520452045204520350045204520Main Steam Valvemm100150150150150200200Safety Valvemm50 5050 5080 8080 8080 80100 100100 100Drain Valvemm40404040404040Water PumpModel/DG6-25x7DG6-25x7DG12-25x7DG12-25x7DG12-25x7DG25-30x5DG25-30x7HeadH175175175175175150210Flow RateQ6.36.312.512.512.52525Motor PowerKW7.57.51515152230Motor Model/Y132S2-2Y132S2-2Y160M2-2Y160M2-2Y160M2-2Y180M-2Y200L1-2Pump Inlet Diameter/φ40φ40φ50φ50φ50φ65φ65Model of Dust Collector
