How high can steam pressure achieve?
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.
Why did early auto makers focus on gas and power engines instead of steam engines?
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.
How does the rotary steam engine work?
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.

What if the steam engine hadn't been invented?
Then the industrial revolution would not have happened and we would all still be living in an agrarian economy.
What negative impact did the steam engine have by James watt?
One negative impact of the steam engine developed by James Watt was the acceleration of industrial pollution due to increased coal consumption. This led to environmental degradation and health issues for workers and surrounding communities. Additionally, the steam engine contributed to the displacement of skilled laborers as machines could often perform tasks more efficiently.
What problem does steam engine solve?
The steam engine helped to power the Industrial Revolution. Before steam power, most factories and mills were powered by water, wind, horse, or man. Water was a good source of power, but factories had to be located near a river.
When does one change their steam boiler?
Some steam boilers can make it to 40 years. Always check the condition of the doors, brickwork, burners, and controls. If there is excessive rusting or leaks, the steam boiler needs to be replaced.
Is the vessel African queen diesel or steam?
Commander L G Dennis, Marine Superintendent (Lakes) (East African Railways and Harbours) in his book "The Lake Steamers of East Africa" 1996 Runnymede,P152-3 writes that it was a railway Marine petrol driven motor boat of 14hp, built in 1930s, 28 ft in length. It was fitted with a mock-up steam boiler and funnel made in the (Butiaba) Marine workshops and that oily rags were burnt to create smoke.
In an interview Daily Press, Norfolk, Va June 06 1997, James Hendricks Snr was reported as explaining that "It really is a vintage African boat,built in 1912 for a British railway company that used it on a lake in Uganda. She originally had a diesel engine--".
Yes it was a motor boat,originally possibly petrol, later diesel, most likely built in the Marine workshops in Butiaba. It appears from a photo in Hepburn's book that a second very similar boat was sectioned into two to create fore and aft situations for close-ups. This sectioning was necessary to allow access for the very large technicolor cameras of the time.
So, it is pure invention to claim African Queen was a steamboat built by either Lytham Shipbuilders or by Abdela & Mitchell
When did thomas newcome build the steam engine?
Thomas Newcomen built his first steam engine in 1712. This engine was designed primarily for pumping water out of mines and marked a significant advancement in engine technology during the early Industrial Revolution. Newcomen's work laid the groundwork for later developments in steam power, including those by James Watt.
What powered transport before the steam engine?
Before steam engines came into use, travel on land was mostly powered by horse. On water, it was mostly powered by wind.
What is uncombustion gases in steam ejector?
Incondensible gases, are gases that do not condense and do not dissolve readily in hot water. Steam ejectors are used to remove these gases from a condenser.
How did the steam engine change transportation in the America?
