CE , BV 5Tph Low Pressure Dual Fuel Steam Boiler Automatic Control System

1. Features of WNS model boiler

WNS series gas/oil fired steam boiler is horizontal three pass fire tube wet back full automatic steam boiler. It normally suitable for 500kg to 20ton/h capacity, use all kinds of gas and oil fuels,such as natural gas, lpg,lng,cng,city gas,biogas, diesel oil,heavy oil.

a. WNS series oil Gas fired steam boiler realize high efficient heat transfer, sufficient burning with brand burner, environment protection
b. Adopted international latest technology for big volume combustion room design, and use brand burner machine
c. Corrugated furnace design make large heat transfer area and protect furnace
d.Using spirally corrugated tube , 1-2 faster heat transfer efficiency and remove hidden danger of welding cracks
e. Adopted wet-back structure that can reduce faults rate and maintenance cost
f. Equipped with protection devices for overheating, overpressure, lacking water, leak detection, flameout etc

3. Advantages of WNS boiler design 

1. You will cost less fuel consumption and improve thermal efficiency.

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. You could use different fuel, we design kinds of available fuel for burning.
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,with this case, boiler thermal efficiency improved, save your cost.
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.
