350Kw 700Kw Oil Fired Hot Water Boiler Horizontal Automatic Running
Features of Efficiency Industrial Hot Water Heater Boiler
1. All the electrical elements have the CE certification to make
sure the boiler safety and long live.
2. Each group electrical heating elements focus on type of flange
connection to make the structure simple, safe and easy to repair.
3. With large steam space and good quality steam.
4. Electrical control cabinet separated from boiler body can make
heat emission easily and many sets of parallel.
5. PLC control systeIn order to optimize the user experience of
Yuanda boiler, in the service process,Yuanda boiler has always been
user-oriented.
Superial designs of WNS hot water boiler
1. Adopt domestic and foreign advanced large furnace design
Increase the diameter of furnace on the basis of original
traditional design.expand the surface of radiant heat exchange. So,
mainly center on radiant heat exchange ,reduce the heat exchange
burden during the second and third return,and make the fuel burning
efficiently,reduce the harmful gas production. Besides,the spiral
hearth in the high temperature area not only increase the area of
radiant heat exchange, but also make a resistance to the smoke
movement.have a obvious effect about radiation heat exchange.
2. The spiral furnace design
Increase the overall strength of the furnace,make compensation for
the heat exchange and shrinkage automatically,avoid the
in-perfection of welded sew crack due to the change of tube plate
heating stress.Therefore,boiler has strong adaptability about
various of fuel,for example,heavy oil,light oil,natural gas,city
gas.
3. Improve heat transfer technology
Apply the technology of heat transfer from “the light of Harbin
institute”.Adopt the design of efficient heat transfer screw thread
pipe and optimize the smoke speed.The output and heat efficiency of
boiler don’t decrease with the extend of operation time,thus
achieve a compact structure with 10% overload capacity.
4. Climate compensation, on-demand heating technology
Considering to the outside temperature and users’ heat
demand,boilers could control the water temperature in the support
of heat source efficiency automatically so that we achieve the goal
of on-demand heating and energy-saving heating.
