Induced Draft Cross-flow Towers for Power Generation, Large-scale HVAC and Industrial Facilities
They are especially well suited for heavy industrial applications in power plants, fertilizer plants, petrochemical complexes and petroleum refineries and the vast majority of new towers are constructed of fire retardant fiberglass because of its high strength and fire/corrosion resistive properties.
It’s an extremely versatile range considering the different request of layouts. An in-line tower is the standard layout for efficiency reasons, but parallel in-line, back to back, and round configurations are also options when the plot plan requires a different approach.
A round configuration may be the right solution for a limited site.
Constructing the tower in a linear way provides the arrangement with the least power consumption, including reduced fan energy consumption and lowest pumping head. Take in account of an efficient entering air access, the tower’s height and cost is minimized.
A back-to-back tower configuration can fit within site limitations when it’s impossible for an in-line layout. Comparing with the linear arrangement, the fan energy and pumping head both increased which will lead to a higher cost but lower thermal efficiency.
If it’s not possible to layout the towers in a single line, it’s ok to split and arrange the towers into two or more units arranged in a parallel in-line configuration considering following points:
