Stainless steel pipelines are commonly used for transporting hazardous chemicals due to their corrosion resistance and durability.

• Stainless steel pipelines are preferred for their resistance to corrosion from hazardous chemicals.

• PVC pipelines are not suitable for hazardous chemicals as they can degrade and leak.

• Carbon steel pipelines can be used for some hazardous chemicals, but may require additional coatings or linin...read more

To calculate the steam of a boiler, you need to know the boiler's efficiency, steam flow rate, and specific enthalpy of steam.

• Calculate the energy input by multiplying the mass flow rate of steam by the specific enthalpy of steam.

• Determine the energy output by dividing the energy input by the boiler's efficiency.

• The steam flow rate can be measured using a flow meter, and the specific enthalpy of steam can be obtained f...read more

The module of a coal fired hot air generator typically includes a combustion chamber, heat exchanger, fan, and exhaust system.

• Combustion chamber where coal is burned to produce heat

• Heat exchanger to transfer heat from combustion gases to the air

• Fan to circulate the heated air

• Exhaust system to remove combustion byproducts

Types of alignment in mechanical engineering include shaft alignment, coupling alignment, and gear alignment.

• Shaft alignment ensures that the centerlines of connected shafts are in the same straight line.

• Coupling alignment involves aligning the coupling halves to ensure smooth power transmission.

• Gear alignment ensures proper meshing of gears for efficient operation.

• Other types of alignment include belt alignment, pulle
