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.
Jun 05, 2019· TRANSFORMER LOSSES - Transformer losses have two sources-copper loss and magnetic loss. Copper losses are caused by the resistance of the wire (I2R).Magnetic losses are caused by eddy currents and hysteresis in the core. Copper loss is a constant after the coil has been wound and therefore a measurable loss.
It includes the power source, electrode cable, electrode holder (or TIG torch or wire feeder and gun), electrical arc, work cable and work clamp. Figure 3 illustrates the welding circuit. For determining proper welding cable size, you need to add together the full lengths of the electrode cable and the work cable.
May 31, 2020· Working Principle of Transformer. The working principle of a transformer is very simple.Mutual induction between two or more windings (also known as coils) allows for electrical energy to be transferred between circuits. This principle is explained in further detail below. Transformer Theory. Say you have one winding (also known as a coil) which is supplied by an alternating electrical …
Answer: Boucholz relay is a device which is used for the protection of transformer from its internal faults, it is a gas based relay. whenever any internal fault occurs in a transformer, the Boucholz relay at once gives a horn for some time, if the transformer is
File Size: 1MB The earthing is defined as the connection of the non-current carrying part like the body of the equipment or enclosure to earth. In grounding the current carrying part like neutral of the transformer is directly connected to the ground. For grounding, the black colour …
Well, there is a lot of difference between neutral and earth. In substations,Neutral wire carries the current back to the transformer neutral point that is grounded at the supplying transformer secondary side, Hence, a voltage drop on the neutr
Ignitor Kits and Electrodes We have ignitors, also known as electrodes, for many common oil burners. You will also find tune-up kits for Beckett, Carlin, Wayne and Weil-McLain burners, as well as a gauge to properly set your ignitors.
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a …
The Start-up Transformer is energized from an incoming transmission line rated at 230KV. This transformer is also a three winding transformer and can feed all four of the switchgear lineups. This transformer is used to power the plant equipment while starting the unit up from cold conditions (i.e. no fire in the boiler).
Bare copper is one of the more common types of copper wire that is used for grounding. Bare copper is sometimes just called grounding wire. This type of copper wire is not covered in any type of protective coating, making it completely unprotected, hence the name.
In section 250.64(E)(3) of the 2014 N.E.C. the code states that the bonding jumper for a grounding electrode conductor raceway or cable armor shall be the same size as, or larger than, the enclosed grounding electrode conductor. This is a code violation and a bonding jumper sized 3/0 AWG or larger should have been used.
