What might you see and what could happen if steam seal on a steam turbine temperature is incorrect?
Asked by Wiki User
Of steam seal on a steam turbine temperature in incorrect could cause damage. This could cause it not to work right.

What is the speed of an steam engine?
Asked by Wiki User
It is the number of strokes (forward and back) the piston makes in one minute. For radial (turbine) and rotary steam engines, it is the number of revolutions per minute.
How high can steam pressure achieve?
Asked by Wiki User
Steam pressure can be raised as high as the rating of the steam generator. Some super-critical steam generators actually operate at over 15,000 psi. Critical pressure/temperature for steam is 3206 psia, and 705^F. This is the point at which steam and water are indistinguishable from one another. All critical and super-critical steam generators require forced flow, (the water/steam is pumped through the generator). The temperature or the pressure can be raised above critical values, with the use of specialized equipment. Generally speaking, non-forced flow boilers can only achieve about 1500 psia, as the density of the steam approaches the density of the water, preventing natural circulation.
How does the rotary steam engine work?
Asked by Wiki User
The rotary steam engine has two identical lobed gears inside a tightly sealed casing to which each lobe of each gear is sealed often with a sliding vane to prevent slippage. One gear may be free spinning, it imparts its power to the other gear, the second gear (or both) drives a shaft which is often connected to a pump or pumps. The steam enters the engine at one side between the gears, it causes the gears to rotate and the steam moves outward around the periphery of the casing, expanding [due to the shape of the casing] as it pushes the gear lobes around to the exhaust side of the engine, where the steam is exhausted either to the atmosphere or a jet condenser, for reuse. Steam power fire engines typically used rotary steam engines.

Why did early auto makers focus on gas and power engines instead of steam engines?
Asked by Wiki User
They are smaller and lighter in weight than comparably powered steam engines, however, most Auto-makers did build steam carriages. White, and Stanley are two of the more well known steam powered automakers.
