Sampling and rejection device

摘要

A sampling and rejection device for a boiler or steam generating system is described. The sampling and rejection device receives the condensate or fluid and allows a volume of the condensate to liquefy or the fluid to build up in the interior of the sampling and rejection device. One or more conductivity, pH, and temperature sensors or probes are positioned in the sampling and rejection device to measure the condensate. The sampling and rejection device includes a collection vessel to hold and temporarily store the condensate. The sampling and rejection device includes an outlet or a return line (to a central boiler) and a drain line. If the sensor measures undesirable conductivity, pH, or temperature in the condensate in the collection vessel, then a valve to the drain line is opened and the condensate is rejected.

主权项

1. A sampling and rejection device for condensate from a boiler steam generating system, comprising:
a collection vessel defining an interior to hold a volume of condensate; the collection vessel comprising a bottom floor; an inlet in fluidic communication with the interior of the collection vessel to pass condensate to the interior, the inlet comprising an inlet nozzle; an outlet in fluidic communication with the interior of the collection vessel, the outlet comprising an outlet nozzle; a rejection outlet in fluidic communication with the interior of the collection vessel, the rejection outlet comprising a dump valve to control flow of condensate through the rejection outlet, and wherein the rejection outlet is positioned in the bottom floor to allow the condensate to drain from the collection vessel; the inlet and the outlet are positioned above the bottom floor of the collection vessel to allow the volume of condensate to build up in the collection vessel; one or more sampling probes in the interior of the collection vessel to measure physical or chemical characteristics of the condensate in the interior of the collection vessel, wherein the one or more sampling probes are positioned or spaced a distance from the bottom floor of the collection vessel; and, a controller in electrical communication with the dump valve and the one or more sampling probes, wherein the controller opens the dump valve based on the readings from the one or more probes.
