CHAUDIERE A VAPEUR STATIONNAIRE A CIRCULATION MULTIPLE FORCEE

摘要

A stationary steam boiler comprises a drum (1) with a separate salt section (5), a superheater of the steam bleeded from the drum (1) and a surface-type attemperator (11) connected on the steam side to the steam superheater. The first evaporating stage is formed by a steam generating surface (9) and a circulation pump (7) connected through a closed circulation circuit to the clean section (3) of the drum (1). The second evaporating stage is formed by the surface-type attemperator (11) connected on the water side through a closed circulation circuit to the salt section (5) of the drum (1). The stationary steam boiler is intended preferably for the use in chemical industry for production of the weak muriatic acid.
