Best Answer

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.


Why supercritical boiler are drumless boilers?

Answer to this question is very simple as the meaning of pressure is force on unit area, so more units of area or simply more area of a vessel containing a pressurized fluid in it exerting force on its walls, means, this vessel is more likely to burst than a vessel which has less diameter thus having less surface area for pressure to create damaging affect for a particular wall thickness. i don't think so Friends Cause .drum wall thickness is also sufficient or more as in comparison to the water walls .thickness main reason behind that in sub-critical boiler we have water and steam mix..inside the drum and we r separating vapour from water in that so for separation we using the boiler drum ..but in super-critical unit ..at critical pressure water is directly converted in to steam so there is no need to using of boiler drum to separate the mixture .and not need to recirculate the water into the wall circuit's also its known as once-through boiler
