Horizontal Boiler Feed Systems

Description

Lockwood boiler feed systems are packaged, atmospheric-pressure, storage tanks built for commercial or industrial steam systems. The storage tank blends makeup water, condensate returns, and water treatment chemicals before being pumped to the steam boiler. The tank is elevated over the feed water pump(s) to
provide sufficient NPSH for water temperatures up to 200°F. Vertical, multistage, centrifugal feedwater pumps are typically utilized since they perform well for low flow, high pressure, pumping applications.

Systems can be fully customized to meet each customer’s specific needs. Systems can be as simple or complex as desired. The storage tank can be made of carbon steel or upgraded to stainless steel for increased life. Makeup water controls can be mechanical, float/probe type with solenoid valve, or modulating via an electronic control valve. Steam preheat packages are typically utilized to elevate the water temperature before sending makeup water to the boiler. Other typical trim items include: thermometer with separable well, gauge glass, and pump suction piping with shutoff valve and strainer.
