Nozzles should not prevent the formation of the water jet, and to create a uniform flame from 1. 5 to 2 meters, breaking the water into droplets, which should not exceed 2 - 3 mm in diameter. Each nozzle has a nominal pressure, which contributes to the proper distribution of water.
Modern requirements for the spray nozzles in the cooling tower part saving energy and water distribution uniformity of sprinkler can be formed as follows: they must ensure developed torch spraying water with a radius of 1. 5 - 2 m at 5 - 30 kPa and not subjected to clogging at the concentration of suspended solids in the recirculating water of about 100 - 150 mg / l in the presence of mechanical impurities (scale, corrosion products of steel and m. p. ).
