as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.
What else can I help you with?
Boiler drum which chemicals are using?
chemical is used in sub critical boiler that is tri sodium phosphate added in durm. The main purpose is raise in pH value , salt is converted in to sludge form
What is entrainment in the boiler?
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. Regards Stephen Pathmarajah
Why shouldn't you store toxic chemicals in metal drum?
Because the drum could rust through and release the chemicals, or be contacted by electricity and cause a fire...if you need to store toxic chemicals in a metal drum, you put a drum liner in first, and pour the chemicals into the liner. A drum liner is a very thick plastic bag.
How are membranophones classified?
Membranophones are classified based on the type of membrane or drumhead they have, such as single-headed (like a tambourine) or double-headed (like a snare drum or conga). They can also be classified by shape, such as cylindrical (like a conga drum) or frame (like a tambourine). The material used to construct the membrane, as well as the method of sound production, also play a role in classifying membranophones.
Can you pressurize a 55 gallon steel drum to drum to another drum?
Yes, you can pressurize a 55-gallon steel drum to transfer its contents to another drum, but it must be done with caution. The drum must be designed to handle pressure, and appropriate safety measures should be taken to prevent accidents or leaks. Additionally, ensure that the contents being transferred are compatible with pressurization. Always follow safety guidelines and regulations when working with pressurized containers.
Why boiler drum manholes are elliptical in shape?
as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.
Why boiler drum in cylindrical shape?
because in cylindrical shape stress concentration is less so it can withstand at high pressure also.
What is the use of steam drum in boiler?
The steam drum separated the steam from the water and stream mixture in the boiler drum.
What is the purpose of boiler drum?
Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator

What will happen when boiler steam drum level goes down?
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.

What is Swelling and shrinking effect in boiler drum?
The swelling and shrinking effect in a boiler drum refers to the physical changes in the drum's volume due to temperature variations and pressure changes during operation. When the boiler is heated, the water inside converts to steam, causing the drum to swell as the pressure increases and the water expands. Conversely, when the boiler cools down or experiences a drop in pressure, the drum may shrink as the steam condenses back into water. This phenomenon is important to consider for the structural integrity and safety of the boiler system.
Why silica increase in boiler drum inspite of 02ppm silca im boiler make up water?
This is due to steam seperation the silica remains in the drum water.

What is drum boiler?
A drumless boiler is obviously a boiler without a drum. The steam is fed into a header, then into a turbine for making electricity. Quality control of the water used is of extreme importance. Since there is no water level in a drum to maintain, feedwater must be constant with no interruption of any kind. With a drum type, water feed can be interrupted for a very short time. Not so with a drumless type.
