摘要： An additive injection pump has a rolling diaphragm mounted between a reciprocable assembly and a cylinder to create a secondary fluid pumping chamber in the lower end of the cylinder. The reciprocable assembly has an internal one-way flow passage between the pumping chamber and an opposite end portion of the assembly having an outlet. The selective positioning of a valve member at the bottom of the reciprocable assembly establishes a predetermined quantity of secondary fluid supplied through an inlet at the bottom of the cylinder. When the cylinder is attached to a housing having a primary fluid stream and the assembly is reciprocated by a fluid motor in the housing, secondary fluid in predetermined doses is injected into the primary fluid stream.

摘要： Operation of a system for injecting a predetermined amount of a secondary fluid into a primary fluid stream uses a liquid additive injection pump driven by a fluid powered motor driven by the primary fluid stream can be selectively suspended by an on/off switch mechanism. The fluid powered motor includes a housing enclosing a differential pressure piston assembly having a piston movable within a housing between upstroke and down stroke positions; a valve mechanism establishing a differential pressure within the housing to produce movement of the piston; an over-center mechanism coupled to the valve mechanism to toggle the valve mechanism between open and closed positions; and an actuating shaft coupled to the over-center mechanism, the actuating shaft including a piston upstroke stop that causes toggling of the valve mechanism at an upstroke position of the piston during normal reciprocating movement of the piston. The on/off switch mechanism axially displaces the actuating shaft relative to the housing such that the piston upstroke stop assumes an offset position when the on/off switch mechanism is in the “off” position whereby the piston upstroke stop can not be engaged to cause toggling of the valve mechanism when the piston reaches its upstroke position. In the “on” position, the on/off switch mechanism positions the actuating shaft relative to the housing such that the piston upstroke stop can be engaged to cause toggling of the valve mechanism when the piston reaches its upstroke position.

摘要： A liquid additive injection pump for injecting a predetermined amount of a secondary fluid into a primary fluid stream wherein a fluid mixing chamber is disposed within the pump housing assembly. A gasket having at least one one-way valve is positioned between the pump assembly components and mixing chamber thereby allowing a primary fluid to pass through the pump assembly and into the mixing chamber where the introduction of a second fluid occurs. The mixed fluids are then discharged through an outlet. The one-way valve gasket assembly acts to prevent the mixed and/or secondary fluid from passing upstream of the gasket assembly and into the pump assembly.

摘要： An inline backwash, flushing filter assembly comprising a header assembly, a rotatable valve assembly, and a filter element assembly disposed within a filter housing assembly. In operation, the controller moves the turn knob of the rotatable valve assembly a one-quarter turn which results in the reversal of fluid flow through the assembly to periodically back flush the filter utilizing fluid from the system inlet. Debris removed from the filter element during the backwash process are immediately discharged from the system through a drain port. Simultaneously, the hydraulic shearing mechanism of the backwash process dislodges and drains debris which may have accumulated on the screen and at the bottom of the lower filter assembly during normal filter operations. The controller then returns the filter assembly to filtration operation by a reverse one-quarter turn of the turn knob of the rotatable valve assembly.

摘要： A reciprocating primary fluid driven motor has a stepped piston in a housing having a center hanging actuator rod which extends into the piston to periodically cooperate with an axially shiftable connector member in the piston which operates valves which establish the reciprocating stroke of the piston by opening and closing valve members on the larger and smaller faces of the stepped piston. A block member with compression spring drivers pivotally mounted inside the piston slides on the actuator rod during movement of the piston. The drivers are compressed in response to spaced stops on the actuator rod during continued movement of the piston until a sudden over-center movement of the block member shifts the connector to operate the valve members to cause reciprocation of the piston. Quiet operation during shifting is provided by shock absorbers. No sliding seal with the actuator rod is necessary. Provision for bleeding air from the housing chamber facilitates startup. The stepped piston is connected to a secondary fluid additive pump to inject metered amounts of secondary fluid into the primary fluid stream.

摘要： A particulate trap regeneration system is provided, which may include a particulate trap having a filter medium configured to remove one or more types of particulate matter from an exhaust flow of an engine and a regeneration device configured to reduce an amount of particulate matter in the particulate trap, as well as a radio frequency-based particulate loading monitoring system configured to determine an amount of particulate matter trapped by the filter medium. The particulate loading monitoring system may include at least one radio frequency transmitting probe configured to transmit radio frequency signals of predetermined magnitude and predetermined frequency toward the filter medium and at least one radio frequency receiving probe configured to receive and measure the magnitude of received radio frequency signals that pass through the filter medium. Further, the system may include a temperature sensing device configured to take a temperature measurement indicative of a temperature of the particulate trap at the time the radio signals are received by the receiving probe and a controller, which may be configured to determine, based on the measured magnitude of received radio frequency signals, a particulate loading value indicative of the amount of particulate matter trapped in the filter medium. The controller may also be configured to perform a temperature compensation including modifying, based on the temperature measurement, at least one of the following: the measured magnitude of the received radio frequency signals that pass through the filter medium or the particulate loading value.

摘要： A power plant with efficient emission control and high turbine inlet temperatures is disclosed. The power plant includes a combustor for the combustion of carbonaceous sulfur-bearing fuel. The combustion of this fuel produces a hot gas with SO.sub.x and NO.sub.x contaminants. This gas is conveyed to a refractory heat exchanger where some of the heat from the gas is transferred to a pressurized air stream. The gas is then conveyed to a fluidized bed reactor. The fluidized bed reactor includes a central chamber with a fluidized bed positioned at the base of the chamber. Heat exchangers are positioned within the fluidized bed. These heat exchangers preheat the pressurized air stream which is then conveyed to the refractory heat exchanger and later conveyed to a turbine assembly. The fluidized bed reactor also includes circulating particulate matter, such as CaO. Ammonia may also be injected into the fluidized bed reactor. When operating at a temperature of at least 1,500.degree. F., the fluidized bed reactor facilitates chemical reactions between the CaO and the SO.sub.x contaminants. The fluidized bed reactor also facilitates chemical reactions between the ammonia and NO.sub.x contaminants. These reactions significantly reduce the contaminants originally found in the hot, dirty gas.
