Steam Engines

Horses were a logical choice for comparison as they were the most commonly used source of power in the 1700s.

John Schulyer did not invent the steam engine, but rather ordered it to pump water out of his copper mine. This engine and the crew that built it originate from london.

The first successful steam engine was Watt's pumping engine.

The first sucessful steam locomotive 'The Puffing Billy' was called such because the puffing sound it made going uphill (under load) reminded people of a puffing billy goat.

A steam engine uses water, steam, and heat.

A vacuum breaker is a check valve installed on the exhaust casing of a turbine. It opens to prevent the collapse of the exhaust hood when the turbine cools and the condensing steam produces a vacuum.

Actually, the steam part is not actually steam, but water vapour. If you look closely at a boiling kettle, there is a clear space between the spout and the actual (steam). That clear space is the steam, which is invisible. What appears afterwards is water vapour.

Children who care. Too many of our elderly are forgotten, shunned, and ignored by their own children because they are too busy to care for them.

Boiler

The early steam engines were atmospheric: they used steam pressure to raise a piston in a cylinder and then by condensing the steam used air pressure to push the piston back down to repeat the cycle.

To condense the steam cold water was injected into the cylinder; not only did this condense the steam but it also cooled the cylinder down. When steam was re-introduced energy was taken from the steam in reheating the cylinder; this resulted in a large amount of wasted energy which translated into the engine requiring lots of fuel. This was improved by using a separate condenser so that the cylinder was kept hot and the separate condenser was kept cold, resulting in a dramatic reduction in the amount of fuel needed.

Also the seals on the cylinder were not perfect so that steam was lost and air leaked in during the cycle (again reducing its efficiency).

With the improvement in cylinder seals and high pressure boilers, later steam engines were able to push the piston in both directions, delivering constant power on both halves of the cycle.

Travel by train was much less expensive, and more reliable, than travel by horse-drawn carriage.

So we can see how much the water is up to so if we know if it is high or low approximately how much it is compare to the steam iron.

Find something you enjoy doing, are curious to learn more about, and think you can contribute to. Also ask to join an employee who already does what you are going to study at work so you can see if this is something you can enjoy doing repetitively for years.

because if the steam is not superheated the remaining water droplets reduce efficiency and can cause corrosion and pitting.

Nearly! Saturated steam, as non-superheated steam is called, is really only steam at the pressure and temperature in the boiler. Once it starts to expand as a gas in doing its work, the pressure and temperature fall and condensation will set in, leaving less and less useful water-vapour to act as a gas. Hence, as you say, the efficiency falls.

yes it did

Most typically it is due to an obstruction in the discharge piping, or air collecting in the top of the pump. Less obvious would be interstage seal leakage, casing leakage, low pressure seal leakage or suction line air induction. Or if a cross connected labyrinth ring is used in the stuffing box this line could have gotten plugged, allowing air to seep in. Improperly positioned suction head could also reduce output, for hot feedwater applications, a D/A or feed tank should be positioned to maintain a positive pressure sufficient enough to prevent steam flashing in the eye of the pump. Seal rings on the impellers could be worn as well.

Check to make sure the suction and discharge valves are fully open, calculate the suction head and compare it to the needed suction head to prevent steam flashing, (Pressure/temperature columns in the steam tables). For instance a 250 F water temperature requires a suction head of, at least, +80 feet ( 20 psig) to prevent flashing. If the suction pressure is too low, increase it or cool the water to a reasonable temperature.

Open the casing vent slowly to expel any air in the pump. If this doesn't work, check for leakage or damaged pump parts, this may require disassembly.

110 - 130 Scfn is what in psi

In Great Britain. By James Watt I believe, who also has the universal unit of power named in his honour

The first Steam engine was invented by Thomas Newcomen in 1710.

Usually, a furnace filled with coal and wood will heat up a tank of water, which will cause it to evaporate and expand. Since water vapor takes up more space, it will quickly travel down a pipe and through a turbine, causing the turbine to spin. And the spinning is what creates energy.
