High-pressure steam locomotive - Wikipedia

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction

For hand fired boilers the grate is 1.8 metre long and is made in two lengths of fire bars resting on a dead plate, on centre bearers and on the bridge supports. The rear wall of the combustion chamber is flat but slopes slightly forward in order to allow the steam bubbles forming on the plate to disengage themselves instead of creeping up the plate.

pressure water boiler reactor brand

While water is kept under low pressure of around 7 MPa, it would boil in the core at about 290 ∘ C [3] so that is why it is called a boiling water reactor. The steam is then fed directly to the steam turbine, so that the coolant acts as a working fluid as well (see Fig. 12.7 ).
