There are 20 cells per arm. 10 of them are placed along the left-most lane while the other 10 are placed in the other three lanes. 80 cells in the whole intersection.
Read MoreIndustrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible. A stable, robust design is also essential – if a
Read MoreThe boiler-turbine unit control schemes have gone through several decades of evolution and, typ-ically, a cascade of PI/PID controllers based on single-input single-output control loops is designed in the plant to fulfill such tasks.6,7 The remain-der of this section

We know that electrical projects are used in many cases in our real life and they require more power when compared with electronics projects. Electrical project circuits use only passive components like capacitors, inductors, resistors, etc.

Its hardness should be below 0.2 ppm. 2. Its caustic alkalinity (due to OH- ) 3. Its soda alkalinity (due to Na2CO3)should be 0.45-1ppm. 4. BOILER PROBLEMS.
Read MoreHow an industrial boiler system works The heart of an industrial boiler system is a hot water or steam boiler operated with a certain kind of fuel. The boiler heats up or evaporates the water inside it, which is then transported to the consumers via pipe systems. In
