XCM for Multiple Boilers. These XCM's are the same as the XC Systems, except they are
provided with a flow control valve manifold and a sample cooler. Each XCM should be
associated with only one feed tank and its make-up line and all of the boilers connected to
that feed tank. All of the boilers must operate at approximately the same pressure. Consult
the factory for possible exceptions. From each boiler, connect a separate blowdown line to
each strainer and flow control valve. The blowdown must enter the side of the flow control
valve and discharge at the bottom. These flow control valves are intentionally installed
backward for longer service.
