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.

Vacuum Deaerators | Veol

Vacuum deaerators are used primarily on water streams to remove dissolved gases including oxygen, nitrogen, carbon dioxide and volatile organics that can produce corrosion, scaling and plugging of piping and injection systems.

Pressurised Deaerators | Spirax Sar

Steam flowrate to the deaerator (m_dot - body text.jpgs) has already been calculated at 334 kg/h. In this example the maximum water flowrate (the ‘actual’ capacity of the boiler) to the deaerator is 9 311 kg/h. Water valves are sized on volume flowrates, so it is necessary to convert the mass flow of 9 311 kg/h to volumetric flow in m3/ h.

Deaerator - Wikiped

Deaerators are commonly used to remove dissolved gases in feedwater for steam-generating boilers. Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (like rust).

Deaerator | CleanBoiler.o

Deaerators are typically elevated in boiler rooms to help create head pressure on pumps located lower. This allows hotter water to be pumped without vapor locking should some steam get into the pump. Reason to Deaerate. The most common source of corrosion in boiler systems is dissolved gas: oxygen, carbon dioxide and ammonia.

Deaerator working principle, Types and Process Contr

Aug 09, 2019· Deaerator solves the aim of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before going in boilers. Most of the deaerators are designed in such how that the dissolved oxygen content within the outlet water is regarding7 ppb by WTC.

Chapter 10 Boiler Feedwater Deaeration | SU

Vacuum deaeration is used at temperatures below the atmospheric boiling point to reduce the corrosion rate in water distribution systems. A vacuum is applied to the system to bring the water to its saturation temperature. Spray nozzles break the water into small particles to …

Installation and Operating Instructions - Precision Boile

A deaerator consists of a pressure vessel in which water and steam are mixed with controlled velocities. This raises the water temperature, thereby liberating the dissolved, non-condensable gases. The effluent may then be considered free from corrosive gases. Their removal by the deaerator protects the boiler, feed pumps, and the entire

Evaluating Deaerator Operation | HPAC Engineeri

When properly installed and controlled, deaerators are designed to provide continuous boiler operation, incurring significant load changes without operator involvement. Variability in pressure, temperature, or water level in a deaerator can cause water hammer, auxiliary-equipment malfunction, and boiler operational anomalies.

Steam Boiler: Deaerator Type for Boil

Deaerator Type for Boiler Deaerator is one of equipment in power plant. Deaerator is used to eliminate corrosive gasses such oxygen in feedwater before supplied into steam boiler.

Innovative Responses Today to Tomorrow’s Challenges Industrial Steam is the leading manufacturer of .005 cc/l pressurized and atmospheric deaerators. Along with the time-tested proven spray-type and tray-type designs, Industrial Steam manufactures a unique line of dual compartment systems that provide 100% guaranteed performance that is unmatched in the deaerating industry.

Deaerator Working Principle and Types - Mechanic

Jan 19, 2017· Vacuum Type Deaerator. The vacuum type deaerator consists of three main components, they are vacuum deaerator, a vacuum pump unit and a boiler feed water pump unit. Deaerator construction is Normally the deaeration tank is made up of galvanized steel or stainless steel.
