PLANT FOR FIRE FIGHTING WITH SUPERHEATED WATER AND STEAM

摘要

FIELD: fire fighting under conditions of subzero temperatures with icing-up and freezing of pressure hoses. SUBSTANCE: water supplied through hose line is heated in the main heat exchanger, then, it is fed to steam generator for steam separation which passes further through hose line to fire seat. Steam generated in steam generator is additionally heated when passing the hose line through coil of additional heat exchanger due to heat of superheated water fed to coil of additional heat exchanger from the main heat exchanger. Water formed in heat generator is returned to the main heat exchanger through diverter. EFFECT: higher efficiency.
