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.
When you drain your hot water heating system to clean the supply tank or to perform other repairs or maintenance, you will need to add water back into the system. The process of adding water to a heating system involves keeping as little air as possible from entering and getting trapped in the system.
Jan 16, 2014· Preheating makeup water is a critical step to maximizing the efficiency of many boiler designs. In the case of a conventional fire tube boiler, a steam sparger is often engineered into the condensate return tank to maximize efficiency by making sure that the boiler does not have to work harder to transform cold water into steam.
Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser.
Oct 11, 2003· When this happens, it makes it difficult to inject water into the boiler. If a locomotive crew encountered this on their trip, it would be reported on the engine work report and corrected. The last thing one wants on a steam locomotive is to not be able to put water into a boiler. Steam locomotives were/are required to have periodic boiler washes.
98% of steam boilers die when the boiler block corrodes through. On steam boilers this always happens above the waterline. Therefore water does not leak out onto the floor (because a steam boiler is only half filled with water). Instead, steam exits the hole and goes up the chimney. In order to test we need to completely fill the boiler with water.
Jul 17, 2017· Adding Water to Boiler Pull the handle of the water feed valve back to allow water to flow into the boiler. Keep a close eye on the water level in your sight glass. When the water has reached an appropriate level, push the handle of the feed valve up to the closed position.
Mar 13, 2007· Pumps, called injection pumps, are used to force feed water back into the boiler. They don't have to be big, and usually are not. All the pump really has to do is to keep up with the amount of steam produced per hour. A little water, makes a lot of steam.
Mar 12, 2007· The steam and water mixture is then expanded, reducing velocity and increasing pressure to a point that it is greater than the boiler pressure. The steam and water mixture can then enter the boiler. Additional energy is also obtained from the enthalpy of the steam as it condenses on meeting the cold water from the inlet, which increases the
