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.

Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
Why boiler drum in cylindrical shape?
because in cylindrical shape stress concentration is less so it can withstand at high pressure also.
What is sagging in boiler?
Sagging in a boiler refers to the downward displacement or deformation of boiler components, particularly in the drum or headers, which can occur due to excessive weight, thermal expansion, or structural weaknesses. This condition can lead to misalignment of piping and fittings, increased stress on materials, and potential failure of the boiler system. Monitoring and maintenance are essential to prevent sagging, as it can impact boiler efficiency and safety. Regular inspections help identify early signs of sagging to mitigate risks.
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.
Why boiler drum manhole in 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.
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.
