steam is water
Steam boilers work by boiling water to generate steam. The steam then is used to heat the engine.
Well, it needs energy from somewhere, something to turn water into steam. Can be coal, can be firewood, etc.
Water is heated to produce steam. The steam is used to power the engine. The power from the engine does the work or powers other instruments that do the work.
Depends on how good you want it to work. The flow rates, energy contents ASO are very different between steam and water so you'd have a lot of tweaking to do to get it to work. But if there's no need to balance the system (no mix of radiators) then it should work, after a fashion.
A steam engine is a heat engine. A steam engine uses boiling water to produce mechanical work. It uses the steam from the boiling water as its working fluid.

You need to cool it down.
A steamboat requires a steam engine, which operates by heating water in a boiler to create steam. This steam then powers pistons or turbines that drive the boat's propellers or wheels. Additionally, a fuel source—such as wood, coal, or oil—is needed to generate the heat for the boiler. Finally, a water source is essential for producing the steam.
the steam cleaners heat up the water till it boils and the water steams it sends the steam through tubes the steam is way to hot for most bacteria and it kills them
Not enough information to answer. Water does not do work when transformed into steam. Once it exists as steam, work can be done as it converts back to water. You will always get less out than you put in. The energy you put in is called the enthalpy of vaporization, (delta H), is also called heat of vaporization or heat of evaporation. The energy required to transform water from a liquid into a gas at atmospheric pressure is 40.68 kilojoules per mole 2260 kilojoules per kilogram. Energy is the ability to do work. Creating steam requires energy. Water does not do work when transformed into steam. Steam, after it is created, can do work and in the normal steam engine, it is then converted back to water. That process involves a few basic issues such as pressure, temperature change and entropy which are not available with the data provided.
Coal or wood
You can turn steam back into water by condensing it, condensation is a process which changes a gas into water.
