A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near C: = Circulating water in m³/h. The "Lime- stone FGD Scrubbers: User's Handbook" is intended for use by utility project managers and project engineers. It provides guidance in selection, installation, and operation of a limestone FGD system, covering all phases from inception of the project through design, procurement, operation, and maintenance of the system.

With the higher sulphur content fuels, corrosion of the gas-side surfaces is a danger: where the surface temperature drops below the dew point of 60°C, water will condense out, which in the presence of acid (°C dewpoint), will rapidly corrode steel and cast iron. The main aim is to maintain the inner-skin temperature of the chimney above the acid and water dewpoints of the flue gases. The highest practicable gas outlet temperature also aids natural draught and the thermal-plume height achieved for dispersal of the products. All fuels which could be used over the life of the chimney should be considered. You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them. Dirty gas applications would generally have a smaller fin density in order to provide allowances for tube cleaning. If the design criterion is such that cold-end corrosion could occur, these sections are designed for recirculation or bypass in order to maintain tube wall temperatures above the exhaust gas acid dew point.

Sulfuric Acid Today United States Published since , Sulfuric Acid Today is a biannual (Spring/Summer and Fall/Winter) trade magazine exclusively covering the sulfuric acid maintenance. The presence of sulfur trioxide (SO3) vapor and HCl also suggests low temperature corrosion problems due to their low acid dew points. Flue gas pressure in waste heat boilers is typically atmospheric or a few inches of water column (in. WC) above or below atmospheric pressure; however, there are applications such as the use of a reformed gas.
