Natural draught

TERMINAL POSITION NATURAL DRAUGHT FANNED DRAUGHT... [Pg.271]

On the large scale, air and water are brought into countercurrent contact in a cooling tower which may employ either natural draught or mechanical draught. The water flows down over a series of wooden slats which give a large interfacial area and promote turbulence in the liquid. The air is humidified and heated as i( rises, while the water is cooled mainly by evaporation. [Pg.762]

In the design of natural-draught towers, a ratio of height to base diameter of 3 2 is normally used and a design method has been proposed by CHILTON(,0 Chilton has shown that the duty coefficient D, of a tower is approximately constant over the normal range of operation and is related to tower size by an efficiency factor or performance coefficient C, given by ... [Pg.766]

Estimate the height and base diameter of a natural draught hyperbolic cooling tower which will handle a flow of 5000 kg/s water entering at 300 K and leaving at 294 K. The dry-bulb air temperature is 287 K and the ambient wet bulb temperature is 284 K. [Pg.868]

Another former method for drying mercury fulminate in a warm air stream made use of a natural draught (Fig. 43). The fulminate is spread in thin layers over... [Pg.155]

The natural draught of the factory chimney was at one time found sufficient for the movement of the gases through the plant, but to-day suitable fans are commonly installed to aid the circulation. [Pg.153]

In the Minifos process of Fisons (now Hydro Fertilizers), ammonia and phosphoric acid (45 - 54 % P2O5) react at 0.21 MPa to give an N/P ratio of 1 (see Figure 12.2). The liquid product is flash-sprayed in a natural-draught tower, where the droplets solidify to form a powder with 6% to 8% residual moisture296. [Pg.287]
