摘要： A method for producing an activated carbon material comprises the steps of producing a hot flue gas stream from a combustion process in a first reactor; routing a first part of said flue gas stream to a second reactor that is substantially vertical; routing a second part of said flue gas stream to eventual venting; injecting and suspending a carbonaceous starting material into said second reactor to devolatilize and activate the carbonaceous starting material to produce an activated carbon material; separating the activated carbon material in a separating device; and routing the gas stream from said separating step to the first reactor for incineration of the volatile contents released from said injecting and suspending step. The activated carbon material is suited for the removal of vapor phase air toxics, such as mercury, from the flue gas of a coal fired power plant. An apparatus for producing the activated carbon material for the same purpose is also described.

摘要： The current invention discloses a method and apparatus for production of hot water or steam in a 4-pass firetube boiler. A waste heat stream is passed through the first and second passes of the boiler, and then routed into a furnace tube (which is the third pass of the boiler) to help suppress the flame temperature and NOx emissions from the burner. The flue gas from the third pass is then passed through the fourth pass of the boiler to transfer the heat energy to the water in the boiler.

摘要： The present invention is directed to a pump and motor assembly assembled in a waterproof enclosure with external threaded connections for pump suction and discharge. The motor can be directly connected to a flexible coupling to a bi-rotational internal gear pump, having self-adjusting mechanical seals and cast iron housing. The pump and motor assembly can be mounted on a sliding base for easy access. Flex hoses can be used to connect pump suction and discharge to couplings attached to the pump enclosure. A discriminating leak detector can be installed at the low point of the pump enclosure to detect and annunciate the presence of oil and/or water.

摘要： The current invention discloses a method of controlling the flow rate of a heavy fuel oil in a fluid transfer apparatus having a point of use outlet to a boiler. It not only controls the flow rate of the fuel oil directly, but also indirectly control the viscosity of the fuel oil without measuring its viscosity. It relies on combustion curves established during the commissioning period using a typical fuel oil at a predetermined trim heater temperature. During normal operation, it sets the flow control valve according to the combustion curves, measures the flow rate and compares to the flow rate target. Instead of using the flow rate measurement feedback to control the flow control vale, it modulates the trim heater to vary the viscosity to arrive at the desired flow rate.

摘要： A system, method and apparatus for remotely installing a flange cover assembly on a fuel transfer tube fixed flange in a containment pit in a nuclear power plant is presented. In one example, the flange cover assembly includes J-bolt spring assemblies in which the feet of the J-bolt are rotated between a clamping and non-clamping orientation to engage with the rear face of the fixed flange. A tool frame is lowered into the containment pit to engage with the flange cover assembly to compress the J-bolt springs and extend the J-bolt foot toward and away from the flange cover. Dual acting cylinders move a spring compression frame on the frame tool to compress and relax the J-bolt spring assemblies.
