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

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.
What is solid wall boiler setting in boilers?

What does DOE heating capacity MBH oil fired heating boilers mean?

What is the mechanical principle used by a boiler service system?
In modern boiler service systems today, many use a mechanical principle known as forced circulation. Boilers are forced to use this method as the pressure inside the boiler is very high, which means the boiler will have to manually force the water/liquid mixture to circulate so that any progress can be made.
Uses of boiler?
A boiler is primarily used for heating. Water is heated and forced through pipes to heating receptacles called radiators. Giant boilers are also used for electricity. Water is heated to turn giant turbines that produce electricity.

What are critical and super critical boilers?
critical boiler operating steam parameter 221.12bar and 375 centigrate . you can rise in pressure and temperatureabove the critical point. that is called supercritical boiler.
What is supercritical boiler?
The following extract taken from an article by Ingo Paul in Energy Issues No 19 April 1999 published by the World Bank [external link] briefly describes the difference between a subcritical and a supercritical boiler. "Supercritical" is a thermodynamic expression describing the state of a substance where there is no clear distinction between the liquid and the gaseous phase (i.e. they are a homogenous fluid). Water reaches this state at a pressure above 22.1 megapascals (MPa) The "efficiency" of the thermodynamic process of a coal fired power (sic) describes how much of the energy fed into the cycle is converted into electrical energy. The greater the output of electrical energy for a given amount of energy input, the higher the efficiency. If the energy input to the cycle is kept constant, the output can be increased by selecting elevated pressures and temperatures for the water-steam cycle. Up to an operating pressure of around 19 MPa in the evaporator part of the boiler, the cycle is sub-critical. This means, that there is a non-homogeneous mixture of water and steam in the evaporator part of the boiler. In this case a drum-type boiler is used because the steam needs to be separated from water in the drum of the boiler before it is superheated and led into the turbine. Above an operating pressure of 22.1 MPa in the evaporator part of the boiler, the cycle is supercritical. The cycle medium is a single phase fluid with homogeneous properties and there is no need to separate steam from water in a drum. Once-through boilers are therefore used in supercritical cycles. www.whizkris.com

What is difference between vertical and horizantal boiler?
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
