ABSTRACT:
A temperature-controlled exhaust particulate collection system used with a high temperature material processing facility has a serial arrangement of devices in the form of a spray cooler, spark arrester and dust collector which receive the particulate-laden exhaust gas flow from the facility and operate to separate and collect the particulates from the gas flow before venting to atmosphere. The collection system also has control devices in the form of temperature sensors or thermocouples, valves and dampers whose respective functions are to monitor and control operations of the collection system. The thermocouples sense temperatures at strategically located points in the exhaust gas flow, and the valves and dampers regulate operation of the facility and the spray cooler, spark arrester and dust collector in response to the temperatures sensed by the thermocouples to maintain the temperatures at or below predetermined limits and to protect the latter from temperature-induced damage.
