A boiler is a closed vessel in which water or other fluid is heated to generate steam or hot water.

• Boilers are used in various industries such as power generation, heating, and manufacturing.

• They can be fueled by various sources such as coal, oil, gas, or biomass.

• Boilers can be classified based on their design, fuel type, and application.

• They require regular maintenance and safety checks to prevent accidents.

The percentage of voltage plus or minus in 3 phase is typically 5-10%.

• Voltage fluctuations in 3 phase systems are common due to various factors such as load imbalances, voltage drops, and harmonics.

• The percentage of voltage variation can range from 5-10%, depending on the specific system and conditions.

• Voltage regulators and stabilizers can be used to mitigate voltage fluctuations and ensure stable power supply.

The equipment of transformer includes core, winding, insulation, tap changer, cooling system, and bushings.

• The core is made of laminated steel sheets and provides a path for magnetic flux.

• The winding is made of copper or aluminum and carries the current.

• Insulation is used to prevent short circuits and breakdowns.

• Tap changer is used to change the voltage ratio of the transformer.

• Cooling system is used to dissipate heat ...read more

The color of silica gel used in boiler is usually blue or orange.

• Silica gel is used in boilers to absorb moisture and prevent corrosion.

• Blue silica gel indicates that it is dry and orange indicates that it is saturated with moisture.

• The color changes as the silica gel absorbs moisture.

• Silica gel is also used in packaging to keep products dry.

Power consumption will be less if the fan runs at low speed.

• The power consumption of a fan is directly proportional to its speed.

• Reducing the speed of the fan will reduce the power consumption.

• This is because the motor will require less energy to rotate the blades at a slower speed.
