摘要:
A method and apparatus for humidifying residential and commercial buildings in which a flue gas generated by a residential or commercial furnace is provided to one side of a porous liquid water transport membrane and habitable space air is provided to an opposite side of the porous liquid water transport membrane in an amount sufficient to provide a habitable space air to flue gas volume flow rate ratio of at least 8.3:1. At least a portion of the water vapor in the flue gas is condensed, providing condensed liquid water which is passed through the porous liquid water transport membrane to the habitable space air side of the porous liquid water transport membrane. On the habitable space air side of the membrane, the condensed liquid water is evaporated into the habitable space air, producing humidified habitable space air which is provided to the rooms of the residential and commercial buildings. Beneficially, no supplemental water source is required for the humidification process.
摘要:
A method and apparatus for humidifying air in which the first side of a permselective water transport membrane is contacted with water vapor laden flue gas from a combustion process having a first water vapor partial pressure and a first temperature and at least a portion of the water vapor is condensed, producing condensed water. The condensed water is transported through the membrane to the opposite side of the membrane, which is contacted with an air stream having a second water vapor partial pressure, which second water vapor partial pressure is less than the first water vapor partial pressure, and having a second temperature, which second temperature is less than the first temperature. Upon contact with the air stream, the condensed water evaporates into the air stream, resulting in a humidified air stream.

摘要:
A heating system having a steam generator or water heater, at least one economizer, at least one condenser and at least one oxidant heater arranged in a manner so as to reduce the temperature and humidity of the exhaust gas (flue gas) stream and recover a major portion of the associated sensible and latent heat. The recovered heat is returned to the steam generator or water heater so as to increase the quantity of steam generated or water heated per quantity of fuel consumed. In addition, a portion of the water vapor produced by combustion of fuel is reclaimed for use as feed water, thereby reducing the make-up water requirement for the system.
摘要:
A combustion system having at least one wall enclosing a combustion chamber and forming a plurality of burner or burner nozzle openings. Disposed within each of the openings is a premix burner or burner nozzle, each of which has a premixed fuel/oxidant outlet proximate the combustion chamber and a fuel/oxidant inlet distal from the combustion chamber. At least a portion of the premix burners or burner nozzles are sized to produce different fuel/oxidant delivery disturbance response times in response to a pressure disturbance within the combustion system. Differences in fuel/oxidant delivery response times are achieved by using burners or burner nozzles having different internal dimensions, different volume flow rates, and, optionally, by varying the fuel/oxidant ratios of the mixtures flowing through the burners or burner nozzles.

A tire cornering power estimation and monitoring system may include a steering torque sensor, a steering wheel angle sensor, a yaw rate sensor, a lateral acceleration sensor, and a speed sensor. The system may further include at least one controller configured to receive signals from the steering torque sensor, steering wheel angle sensor, yaw rate sensor, lateral acceleration sensor, and speed sensor and send a notification if the signals indicate that one or more of the vehicle's tires need to be checked or serviced. The system may further include a notification system configured to receive a signal from the controller and indicate that one or more of the vehicle's tires need to be checked or serviced.
摘要:
A method for steering pull compensation to maintain a steering load below a predetermined threshold value. A straight line driving condition is verified through vehicle sensors and/or GPS, drive torque control is performed such that the steering load is kept below the predetermined threshold value. The steering pull compensation method may be disabled by a vehicle operator and is disabled in the absence of a verified straight line driving condition.

A magnetic memory unit includes a tunneling barrier separating a free magnetic element and a reference magnetic element. A first phonon glass electron crystal layer is disposed on a side opposing the tunneling barrier of either the free magnetic element or the reference magnetic element. A second phonon glass electron crystal layer also be disposed on a side opposing the tunneling barrier of either the free magnetic element or the reference magnetic element to provide a Peltier effect on the free magnetic element and the reference magnetic element.
