By most manufacturers' standards, high-quality steam is 99.5-percent dry saturated steam. For a boiler to provide an appropriate amount of such steam safely, efficiently, and at the correct pressure, the amount of water inside of the boiler must be carefully controlled. This article will discuss problems associated with high- and low-water-level conditions, the effects of steam pressure and ...
The steam rising out of nozzles with a great velocity drags air by the fuel bed, furnace, flue passage and then to the chimney. Here the steam jet is pushing or forcing the air and flue gases to flow through boiler hence it is forced steam jet draught. Advantages of
A pressurized system results in water boiling at a higher temperature. Hence, the more that steam pressure builds inside the drum, the boiling temperature of the water increases, resulting in a reduction in steam production overall. In essence, the boiler is self-controlled via the steam pressure it produces through its operation.

TYPES OF BOILER: Different types of boiler used in various industries for different purposes. Types of boiler depending on boiler capacity, steam pressure, and other parameters. Here types of Boilers can be classified as: 1. Types of Boiler according to contents in
According to the location, it is necessarily a convection-type of heat exchanger providing forced and once-through flow path of feedwater, effectively making it heater inside the boiler or steam generator.
Whatever type of boiler is used, steam will leave the water at its surface and pass into the steam space. Steam formed above the water surface in a shell boiler is always saturated and cannot become superheated in the boiler shell, as it is constantly in contact with the water surface.
Union Pacific steam locomotive No. 4014, the Big Boy, is in one piece again nearly two years after the behemoth was disassembled to begin its restoration. The Union Pacific Steam Team recently hoisted the Big Boy’s more than 250-ton boiler and rear engine into the air with two massive cranes and reconnected it to its front engine.
