Introduction of WNS gas / oil fired steam boiler:

WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.

Technical advantages:

1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.

2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.

3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.

4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

What is the difference between ID fan and FD fan? - Quo

Oct 03, 2016· ID fan is basically mentioned here for Induced draft fan and ID fan is always located between dust collector and chimney. ID fan will take the hot flue gases from furnace via dust collector (dust separation system or Fume Extraction system) and wi

ID Fan Design Considerations • FG

ID fan is one of your plant most important items. It permits you to exhaust flue gases to the atmosphere from your kiln, boiler, etc. An effective design will permit you to operate your ID fan in a good efficiency range so, don’t be too conservative in designing ID fan, because can cost you extra money in two ways:

Induced Draft (ID) Fan Lubrication System Design Revi

problems caused from the induced draft (ID) fans since initial commissioning. The ID fan problems have arisen from the bearing lubrication system which provides oil recirculation to the induction motor bearings and fan main shaft bearings. Consequently these issues have caused half-load unit (225 MW)

what is the difference between id fans and fd fa

Normally both fans are used in thermal power plant. FD fan is used to draw the air from atmosphere to boiler that will create positive pressure inside the boiler. But ID fan is used to evacuate the flue gas from boiler to atmosphere via ESP ,chimney and that will create negative pressure inside the boiler..

Efficient & Durable Industrial Fans | Air Handling Solutio

Our rugged industrial fans are designed for longevity and efficiency in air, gases, dust and materials handling applications and are fabricated from materials including Hastelloy, ASTM 36, high strength carbon steels – A514/A517 and exotic alloys to endure long-lasting use in high temperature, high pressure, corrosive environments.

Boiler-Tuning Basics, Part I - POWER Magazi

In any coal-fired boiler, airflow demand is a function of the boiler firing rate or boiler demand (Figure 3). Gas- and oil-fired boilers have lower O 2 requirements at higher loads. 3.

How FD and ID fan control the air flow - Answe

File Size: 877KB FD or Forced Draft Fans supply combustion air to the boiler. Different combustion controls demand a supply of combustion air in different ways but what they have in common they control the FD fan

ID Fans - Primasonics International L

ID fan imbalance; ID fan imbalance is caused when either particulates and fluid build up within hollow compartments of the ID fans or when an uneven layer of build-up accumulates on the fan’s blades. The delicate procedure of balancing involves the adding or removing of weight, in order to move the weight center towards the axis of rotation.
