How a steam boiler works | Viessmann

The way a steam engine works is extremely similar to a steam boiler. Instead of gas, coal was applied to a fire to produce lots of heat. A boiler full of water was located just behind the fire so the water would eventually heat and evaporate. This steam would rise and follow a pipe system into a cylinder. Within the cylinder there was a piston.

Water softeners and Reverse Osmosis systems help to prepare the water by removing dissolved solids like calcium and magnesium to reduce the potential for scale build-up within the boiler. Feedwater tanks are also a part of the water treatment as they use heat to reduce the number of dissolved gases within the water that can contribute to oxidation and corrosion within the boiler.

What Causes High Pressure on Steam Boiler — Heating …

31/10/2014 · A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
