Listing ID #2483959

In Forced Circulation Evaporators water is distributed in tubes like a fine film layer on surface of tubes. Due to less wetting in surface and scaling, fouling materials will form a layer of insoluble scale that reduce its evaporation capacity. During evaporation, scaling materials such as calcium, magnesium & silica salts are forms quick and insoluble layer of scales. This will reduce heat transfer and affect system performance. For that, we recommended forced circulation system.In that design, feed is flow inside of tube with tube filled condition and with high velocity and pressure. Due to velocity and pressure, boiling on tube surface is reduced. Pressure inside of system is maintained to avoid boiling inside of tube by vapour head pressure. Further velocity in forced circulation keeps surface on wiping and cleaning. This will not allow developing scales on surface by force of feed water.Feed vapour is separated in vapour separator. Further, with forced circulation system, we can run system with semi slurry conditions with very high concentrations There is no boiling on calandria and heating only happened in calandria. Boiling happened in vapour separator and concentration without scaling is achieved. Further high concentration water and semi slurry water is processed.This will help to separate salt by crystallizer, pusher centrifuge or dryer. By forced circulation system, we can achieve zero discharge system effectively. We installed many forced circulation system up to 80kld capacity. This system is used to high fouling, scaling water, salt separation by crystallizer and pusher centrifuge.
