20130099014 | System and Method of Controlling Condensing and Non-Condensing Boiler Firing Rates - Hydronic heating systems, controllers for such systems, and methods of using/operating same are disclosed herein. In one example embodiment, such a system includes at least one condensing boiler and at least one non-condensing boiler, and at least one controller configured for utilizing at least one PID control program to generate at least one signal for controlling firing rates of one or more of the boilers based upon sensed water temperature and temperature setpoint inputs. Depending upon the mode of operation, the at least one PID control program is a first PID control program dedicated to controlling only the at least one condensing boiler, or is a second PID control program dedicated to controlling only the at least one non-condensing boiler, or includes both the first and second PID control programs. Also, outside air temperature serves as a basis for generating the temperature setpoint inputs. | 04-25-2013 |
20130020078 | Oil Recovery Process - An oil recovery process entails recovering an oil-water mixture from an oil bearing formation and separating the oil-water mixture to produce an oil product and produced water. The produced water includes suspended and dissolved solids and is subjected to treatment which removes suspended and dissolved solids therefrom. The treated water is then directed to a forced circulation steam generator that includes a furnace having a burner, water cooled walls and an evaporator unit. The treated water is pumped through the water cooled walls and the evaporator unit. The water passing through the water cooled walls and evaporator unit are heated to produce approximately 10% to approximately 30% quality steam in both the water cooled walls and the evaporator unit. The steam is collected and separated from a water-steam mixture to produce high quality steam, on the order of 95% or greater quality steam. This steam constitutes injection steam which is injected into an injection well to facilitate the recovery of the oil-water mixture. | 01-24-2013 |
