摘要： A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft{circumflex over ( )}2 deg F.). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit.

摘要： A gas-fired atmospheric pressure steam humidifier having high efficiency and ultra-low NOx(3) emissions is disclosed. In some examples, the gas-fired humidifier can have an efficiency of greater than 90 percent and a NOx(3) output of less than 20 parts per million (ppm). In one aspect, the humidifier includes a secondary heat exchanger having a first heat exchange section for pre-heating combustion air and a separate second heat exchange section for pre-heating make-up water, wherein the first and second heat exchange sections are in heat transfer communication with exhaust gases generated by the gas-fired burner and combustion blower assembly. In some examples, the first heat exchange section includes orifices for enabling flue gas recirculation.

摘要： A steam dispersion system includes a header defining a first end and a second end, a plurality of steam dispersion tubes extending upwardly from the header, a condensate drain outlet located at the first end, a hollow pipe positioned within the header, the pipe defining a length extending in a direction generally from the first end to the second end, the pipe defining a main humidification steam inlet located at the first end and a main steam outlet that is within the header. The hollow pipe is configured to receive steam flowing in from the main steam inlet toward the main steam outlet. The pipe may define a plurality of orifices along the length thereof for allowing steam flowing through the pipe to enter the header for distribution through the dispersion tubes. A steam re-direction structure directs steam flow leaving through the main steam outlet back toward the first end of the header.

摘要： With respect to atmospheric steam generating humidifiers, the present disclosure resolves the problem of end-users not adjusting the drain interval of the humidifier by using an electronic controller to automatically choose an appropriate drain interval without requiring any user input. The electronic controller accomplishes this by receiving input data from a sensor that measures a water quality parameter, automatically determining a drain interval based on the received data, and sending an output control signal to a drain water control valve to execute a drain event in accordance with the drain interval. In some examples, the electronic controller utilizes a look-up table correlating the water quality parameter to a total dissolved solids or cycles of concentration value.

摘要： A cycles of concentration (COC) control process and system for an evaporative media cooling system having a water storage tank in fluid communication with a drain valve and a refill valve is disclosed. In one step, the COC control process includes the step of executing a plurality of discrete refill events to maintain a level or volume of water within the storage tank. In another step, the COC control process includes the step of executing a discrete drain event, equaling the volume of a refill event, after a discrete refill event has been executed when necessary to maintain a target cycles of concentration value of the water within the storage tank. In one embodiment, a discrete drain event is executed when the number of refill events is greater than or equals a target cycles of concentration of the water in the storage tank.

摘要： A staging control process for an evaporative media cooling system having a plurality of media stages is disclosed. In one step, a leaving air dry bulb temperature setpoint for air exiting the evaporative media cooling system is received or defined. In one aspect, an expected media exit dry bulb temperature is calculated for each media stage based on a dry bulb temperature and a wet bulb temperature of air entering the media cooling system and based on a measured or assigned condition of the media. In another aspect, an estimated combined leaving dry bulb temperature is calculated for different combinations of activated and deactivated media stages. Once the estimated leaving temperature is known, the method can then activate the media stage(s) associated with the combination that has an estimated combined leaving dry bulb temperature that is nearest to but less than the leaving air dry bulb temperature setpoint.

摘要： A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.
