POWER SECTORS
Cooling Towers are one of the most critical equipments in any power plant as these dissipate waste heat in the most efficient and cheapest way. Thus they play an important role in enhancing the overall efficiency of the power plant and also conserve the most precious natural resource, the water.
Cooling Towers for power plant capacities 500 MW and above are quite large in size due to large quantity circulating water and as a result require large space for their locations. Optimized sizing for design and planning for construction of the towers are crucial activities that demand considerable expertise in the field.
Over the years SPECTRUM has acquired the expertise in this field comprising of thermal, mechanical, hydraulic, civil and structural aspects. Presently, the following services in the field are offered:
‣ Design and Engineering of Natural Draught and Induced Draught Cooling Towers
‣ Design and Engineering of Counter flow as well as Cross flow Towers of Induced Draught Towers
‣ Design and Engineering of Towers with Film Fill (Cellular Types) and Splash fill ( Splash Grid, Doron V Bar, PSC Laths, Trickle Grid/Block, All Legacy Fills like Wooden Slats, Wedges, etc.)
We cover the entire systems of cooling towers and provide services from conception to commissFollowing is the list of our references: ioning through planning. Following is the list of our references:
