Our “Green” Solution
The “Green” Cooling Tower harnesses this hydraulic energy to drive a hydro-turbine, which turns a fan shaft and fan blades on the unit. A sufficient amount of air flow is generated by this mechanism to cool water flow supplied to the turbine to the optimal approach to the saturation (wet bulb) temperature of the air. This cooling is done by draining the return water out of the hydro-turbine into a spray nozzle assembly which distributes the water evenly across the section of film fill. The air flow generated flows upwards in a counter-flow fashion, exchanging heat with the water across the film fill. The water then drains back into the existing tower’s basin. Furthermore, by unloading water flow/heat loading from the existing tower, the existing tower achieves colder water with the same amount of air flow in summer months, thus reducing overall supply water temperature. The amount of reduction in water temperature achieved is dependent on the baseline performance capability of the existing tower and the number of “Green” Cooling Tower units applied. In winter months, air flow and hence electrical usage can be reduced on the existing Cooling Tower fans with the “Green” Cooling Tower supplying supplemental cooling capacity.
The “Green” Cooling Tower technology is an innovative means of adding supplemental cooling capacity to a Power Plant or any Industrial Process without adding additional operating costs in the form of electricity or requiring significant capital investment in engineering or infrastructure. The costs of implementing this technology are immediately recoverable in terms of reduced fuel costs and increased power output capacity in summer months, as well as reduced Cooling Tower electricity usage in winter months. Most importantly, the “Green” Cooling Tower operates with no supplied electricity, using instead the hydraulic pressure of the water supplied to the unit to generate air flow which cools the water.
The benefits to Power Plants, in particular, will be significant in terms of energy impact. This technology will significantly impact a Power Plant’s ability to produce maximum electricity at minimum fuel usage. This in turn directly reduces the carbon footprint of the Power Plant. Besides establishing a lower cost of operation in the peak power usage periods of summer months, Power Plants will also be able to export more Power to the grid, giving them more pricing power in unregulated markets, and reducing consumer pricing in regulated markets. The net result will be that Power Plants profits will increase through reduced costs and increased output capability, while costs to the consumer will decrease. Although money does matter, the most significant benefits may be our contribution to sustainable energy policy and minimizing the impact on the environment.
