There are basically two types of boilers one is the conventional boilers with a drum or shell in which water (obviously well treated water) is heated and as it is heated it produce stem. The steam occupy the top space and the bottom part is filled with water hot and pressurised. When the process requirements whether it is for steam turbine or for chemical process we need dry steam. If the water level is too high and or if the boiling velocity is too high the water droplets instead of leaving the boiler drum as steam some water droplets leave with the steam. This is no good for the process as we need steam but we are getting water. This water entering the system is called entrainment. If the boiler is highly rated i.e. we are heating too much and heating very hard then the top of the water face on the drum through which the steam leaves takes water drops as well. This is called entrainment.

Does high temperature affect air entrainment on concrete?
Of course it does. One thing can be said about air entrainment everything affects it in concrete. High temperature can lower the effectiveness of air entrainment products. Typically requiring a higher dosage of air entrainment to get the desired air content.

What is Auxiliary Boiler?
An auxiliary boiler is a secondary boiler used to support the main boiler in a steam power plant or marine vessel. It is often used when the main boiler is unable to meet the steam demands, providing additional steam capacity. Auxiliary boilers can also be used for heating purposes during maintenance or downtime of the main boiler.
