Generator
Boiler drum inclination is kept at 1:50 with the horizontal i.e. around 6 to 8 degrees.
I think you mean "perforated" baffles. The baffles provide a surface area to collect any entrained water in the steam. The perforations are simply holes to let the steam pass through. The velocity of the steam is relatively low in this section, preventing the water from being re-entrained from the wet surfaces of the baffles.
the difference between a drum kit and a drum machine is that a drum kit you perform naturally with your hands using sticks to change the pitch on whether it is high or low, and a drum machine is like a little electronic board where all you have to do is choose which percussion instrument you want and edit the way the rhythm sounds. personally i prefer the drum machine, much easier ;)a drum kit is an instrument that you can play. a drum machine is a computer that generates a drum track. drum machines are commonly used in techno and hip-hop.
Its origins lie between the Caribbean Steel Drum and the Swiss Hang drum but the Hapi was invented in the USA and is a recent invention.

The steam drum separated the steam from the water and stream mixture in the 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
Due to pascals law
In the steam drum, where steam exits and flows to the superheaters.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
This is due to steam seperation the silica remains in the drum water.
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.
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
Boiler drum inclination is kept at 1:50 with the horizontal i.e. around 6 to 8 degrees.
Steam drums are used on recirculating boilers that operate at subcritical pressures. The primary purpose of the steam drum is to separate the saturated steam from the steam-water mixture that leaves the heat transfer surfaces and enters the drum.
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.
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.
