NITROGEN-FILLED EXTENSION TANK FOR BOILER

摘要

FIELD: heating.SUBSTANCE: nitrogen-filled extension tank for boiler is integrated in the boiler body to compensate for hydraulic hammer caused by thermal expansion of heat carrier circulating in the body. Nitrogen-filled extension tank includes nitrogen-filled vessel with heated water inlet and outlet devices and elastic chamber immersed in the vessel and designed to receive and displace heated water, with its volume changing uniformly according to heated water influx or discharge.EFFECT: compensation of water hammer caused by thermal expansion of heated water.3 cl, 6 dwg
