Boiler - Wikipedia

Boilers can be classified into the following configurations: Pot boiler or Haycock boiler/Haystack boiler A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere.

High Pressure Boiler: What is it? Types & Characteristics

The boilers are able to heat the water used in bathrooms and use steam to heat the different rooms throughout the building, allowing them to become warm. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. High-pressure boilers …

High Pressure Boiler Manufacturers | IQS Directory

Apr 19, 2019 · By definition, high pressure boilers are built to a maximum allowable working pressure (MAWP) above 15 psig, while low pressure boilers are designed for operation at 15 psig or below. Low pressure boilers are most commonly utilized in heating applications and require less maintenance than that of a high pressure unit.

Understanding Boiler Pressure | Boiler

High pressure boilers use water-tubes since fire-tubes are not sufficient in regards to pressure or temperature, even if the boiler were larger and burned more fuel. In order for fire-tube boilers to create the same amount of pressure, the system would require thicker walls and bigger tubes but still would not be able to reach high enough

Pressure vessel - Wikipedia

Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness, and is the ideal shape to hold internal pressure. However, a spherical shape is difficult to manufacture, and therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end.

Boiler – level control, high and low water limitation | VEGA

High process pressures and a highly compressed vapour phase are the normal operating conditions inside boilers. The size of the steam generator is what determines the quantity of saturated steam that can be fed into a heat exchanger. Reliable control of the water level and limitation of high and low water levels are therefore extremely important.
