Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
The first step consists of grounding the coal blocks evenly to fine fragments, and placing them in a furnace that is attached to a water boiler. After undergoing heating and combustion, the water boils, and the resultant steam is used to drive the turbines to generate electricity.
Both diesel engines and gasoline engines convert fuel into energy through a series of small explosions or combustions. The major difference between diesel and gasoline is the way these explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

What Is the Difference Between PSI and PSIG? PSI and PSIG are both units of measurement for describing the amount pressure a gas or fluid is exerting. However, PSIG specifies what the measurement is relative to, whereas PSI does not.
Natural gas is mostly methane while propane is just propane. Natural gas is delivered via gas mains or pipes while LPG-propane comes in a gas bottle, cylinder or tank. CNG comes in heavier natural gas bottles. There are many other difference as well, including energy content, storage, density and chemical formulas (formulae).
boiler use many type of working fluids like water, mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers
If the shaft of a centrifugal pump is turning at the same revolutions per minute, a pump will pump to the same height regardless of what type fluid. The only difference is the amount of power
The coolant inside a radiator can become boiling hot after the engine runs for a relatively short time. The cap on a hot radiator is under a lot of pressure and is holding back a lot of steam and hot fluids. The radiator won't "explode" if you remove that cap, but it will spew steam and hot fluid everywhere.

The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil.
Gasification as incomplete combustion Gasification is most simply thought of as choked combustion or incomplete combustion. It is burning solid fuels like wood or coal without enough air to complete combustion, so the output gas still has combustion potential. The unburned gas is then piped away to burn elsewhere as needed. Gas produced by this method goes by a variety of names: wood gas
Jan 22, 2005 · A steam generator usually has forced (pumped) water circulation through a series of tubes and is kept under higher pressure to prevent steam formation in the tubes. Ultimately, the pumped water goes into a steam seperator where the pressure is reduced somewhat and some of the water flashes into steam.
Steam and feedwater together is called working fluid. The name “steam generator” is also still called “boiler,” but modern steam generators in the supercritical class do not involve the “boiling” phenomenon. The fuel-firing equipment of a steam generator should completely burn the fuel used in the furnace to release as much energy
