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.
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.
To protect the integrity of the boiler and ensure it continues to produce good steam quality, it is important to properly treat the feedwater, or the water going into the boiler. A water treatment system will: • prevent deposits on boiler surfaces that weaken metal and cause heat transfer losses,
Losing water, but no leaks — Heating Help: The WallBoiler Not Keeping House Warm — Heating Help: The WallSteam system losing water.. a new question for an age oldSee more results Denbigh’s boiler would have operated with sea water. The salt in sea water would eventually cause scale and corrosion in the boiler and other compartments, but the salt would be retained within the boiler as the steam – pure water – was diverted to the engines. Once spent, this steam would be condensed and returned to the boiler.
The Importance of Water in Boilers A closed hydronic space heating system may only require chemical water treatment and periodic water quality checks, while the make-up demands of an open steam system may require a full water treatment system.
Jun 14, 2018· A water meter will allow youto determine how much water is being added to the steam boiler. This will also give you a heads up if there are any system leaks. Water meters are sometimes built into the automatic water feeder. Start-Up. Heat boiler up. Avoid making steam. Skim the boiler.
Boiler Logs Are Important. The majority of boiler accidents can be prevented. One of the most effective tools is the proper use of operating and maintenance logs. Boiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing.
File Size: 195KB Boiler feedwater. With the development of the marine steam engine, their boilers also required a continual supply of feedwater.. Early boilers used seawater directly, but this gave problems with the build-up of brine and scale. For efficiency, as well as conserving feedwater, marine engines have usually been condensing engines.By 1865, the use of an improved surface condenser permitted the use
It also makes sure that the pressure on the wet return where it enters the boiler is the same as the steam, which makes sure that the steam pressure -- if any -- in the boiler doesn't force the water out of the boiler into the wet returns. Bigger is better for headers, but there is a cost/benefit consideration.
Ultimately it can lead to tube failures. Water serves two main purposes in boilers. The first is probably obvious; its there to be made into steam. The second is more subtle. Water is a coolant in a boiler. You have a flame that may be as hot as 2
Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.
