Steam Accumulator Tank (Steam Accumulator)

Some businesses (EPS, glass, cardboard) need peak steam loads three to four times their average load. This peak demand lasts a few minutes.

To meet these heavy loads, sizing the steam boiler for the large capacity means, for most businesses, both a higher initial investment cost and higher energy cost than normal loads would require.

Boilers can meet fluctuations in steam demand to a certain degree. Energy is stored in boilers in the form of hot water at saturation temperature. If the process's steam demand suddenly increases, pressure inside the boiler drops. The steam accumulator tank meets the high steam demand.

Steam Accumulator Tank Design

A steam accumulator tank is designed as a cylindrical vessel that responds to steam accumulation as quickly as possible. With İtimat Kazan ve Makine Sanayi's 50 years of experience, we manufacture it at the required pressure, in horizontal or vertical form, cylindrical, dished-head and insulated.

The design is carried out in compliance with the PED 2014/68/EU European Pressure Equipment Directive. Steam accumulator tanks are manufactured and certified to the EN 13445 European standard.

The size of the steam accumulator is determined through thermodynamic calculations. The energy calculated from the enthalpy difference of the saturated water inside the accumulator is the most important input in calculating the steam quantity.

The stored steam pressure, steam temperature and tank dimensions are factors that affect the strength calculations.
