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.

Steam Purity - boiler-wrba.o

File Size: 258KB Trouble shooting poor steam purity •Monitor closely the boiler water chemistry to make sure it is within recommended limits. •Monitor the saturated steam for proper chemistry limits. •If NO online monitoring equipment then monitor the saturated silica conductivity values of the saturated steam and super heated steam (if sampling is available).

Steam Superheater in Boiler: Role, Benefits, Typ

File Size: 1MB Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the

Superheated steam - Wikiped

To produce superheated steam in a power plant or for processes (such as drying paper) the saturated steam drawn from a boiler is passed through a separate heating device (a superheater) which transfers additional heat to the steam by contact or by radiation. Superheated steam is …

Technical Guidance Document: Steam Purity for Turbi

Boiler in which steam (generated in heated evaporator tubes) is separated from water in an unheated horizontal pressure vessel (drum). The liquid phase is recirculated to the evaporator. Feedwater Water that is pumped into a boiler or HRSG to balance the steam production

Steam Quality – Plant Operations Require High Steam Quali

May 11, 2011· As the saturated steam acquires more energy from the boiler combustion process, the steam achieves a high quality, as represented on the chart by moving left to right, from points B to C. The increase in energy gained by the steam from points C to D goes toward the superheat of the vapor.

Steam Calculators: Boiler Calculat

(Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Properties of Saturated Steam - Imperial Uni

File Size: 1MB Vacuum steam is the general term used for saturated steam at temperatures below 100°C. Example Stress in Steam Boiler Shells from Boiler Pressure - Calculate stress in in steam boiler shells caused by Wet Steam Quality and Dryness Fraction - Introduction and definition of steam quality and dryness fraction including calculating wet

superheat. Steam quality ranges from 0 to 100% and is defined as the ratio of the amount of saturated steam vapor to the total steam amount (which may consist of both saturated steam vapor and liquid). A 100% steam quality translates to zero amount of saturated steam liquid and, in this condition, the steam is termed to be “dry.” 4.

Boiler Systems: Strive for steam quality - Plant Servic

The criticality of steam quality varies by application. The greatest threats to industrial steam quality are maintenance and lack of knowledge of how the system is supposed to be running correctly. Industrial and utility boiler systems alike are under increasing scrutiny for steam quality. Steam quality plays a significant role in boiler performance and efficiency, production reliability, and the longevity of the …

Cleaver-Brooks | Reference Center | Boiler Basics | Ste

The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.

Boiler Efficiency and Steam Quality: The Challenge

In some circumstances, steam demand increases are so disruptive to boiler operation that boiler life as well as steam quality suffers. In some cases, the external water level indicator shows the water level as satisfactory, yet the actual level of the water/steam mixture in the boiler may be filling the steam space and water may be literally pouring into the steam lines by steam demand syphoning.
