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.

Superheaters - an overview | ScienceDirect Topi

The outlet pressure of the superheater in a subcritical drum boiler, for example, is for example at 18.6 MPa, while the outlet pressure of the reheater is only 4.0 MPa. When a supercritical boiler is operated under normal load, the heating surfaces of the reheater and superheater have to increase in order to meet the heat requirement for

Superheater tubes for boilers — Sandvik Materials Technolo

Sandvik superheater tube and reheater tube materials cover all types of fuel, such as coal, gas, oil, black liquor and biomass. The Sandvik program also includes composite tubes consisting of two different alloys fully bonded together.. Increased efficiency in coal-fired power boilers

However, the overall energy efficiency of the steam plant (the combination of boiler, superheater, piping and machinery) generally will be improved enough to more than offset the increased fuel consumption. Superheater operation is similar to that of the coils on an air conditioning unit, although for a different purpose. The steam piping is

Steam Superheater in Boiler: Role, Benefits, Typ

Boiler Superheater’s Manufacturing. Our superheaters are manufactured according to the IBR Regulations.Thermodyne manufactures both coil type and shell type superheaters depending upon the type of boiler and boiler capacity.. Coil type superheaters design generally consists of 180 o coils welded through the headers on both the sides. In a coil type designs steam is inside the coil and flue

Superheater - an overview | ScienceDirect Topi

Feb 10, 2011· The superheater outlet steam temperature may drop sharply due to water carryover from boiler and/or due to malfunction of the attemperator system. In either case, immediate action must be taken to reduce carry over and bring back steam temperature within specified limits.

Superheater and Reheater Temperature Control in Boile

The superheater temperature control can be done by many ways. Methods like desuperheating by water injection, flue gas flow diverting, burner tilting are few of the commonly adopted systems. In large capacity boilers the injection type desuperheating is adopted for superheater temperature control. Reheater in power boilers can also be technically classified as superheaters, however the type of
