MoreSteam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment.
MoreSteam injectors are used to inject live steam into feedtanks to drive off the dissolved oxygen. Considerably reducing the amount of oxygen scavenging chemicals required. Maintaining high and consistent feedwater temperature to the steam boiler.
