Designing a steam power plant

[VelocityGirl]

Hey guys. I've been asked to design a steam power plant for a college assignment. I understand most of what I'm doing, but I was wondering what are general values for the minimum and maximum pressures and temperatures which can be handled by a typical boiler, condenser and turbine? Would be useful when choosing values.

 

Thanks.

I do not think there are "typical pressures". It is very dependent on the size.

 

Small boilers might not hold a very high pressure and if it is a hobby project, to build at home you definitely want to be on the safe side. For small table-top steam engines, you might just as well buy a complete kit at a local shop. That will come with a manual, and will tell you all about the safety.

 

Large scale industrial boilers can achieve hundreds of bars. Here's a link to a supercritical steam plant, operating at 280 bar, 600°C.
