Hence in these evaporators the flow velocity in the tubes is kept very high. In a forced circulation evaporator, liquor is pumped from the bottom cone of the vapor body through the tubes of the heat exchanger, where heat is added, and back into the vapor body where evaporation occurs. Forced Circulation Evaporator. The Pump maintains good velocity of liquid in tubes. At first glance,the addition of a pump and additional controls will add to the installation, operating and maintenance costs. Forced circulation evaporators are used if boiling of the product on the heating surfaces is to be avoided due to the fouling characteristics of the product, or to avoid crystallization. Forced Circulation Evaporator. Vertical shell-and-tube heat exchanger of short tube length, with lateral separator arranged at the top. The circulating product is heated when it flows through the heat exchanger and then partially evaporated when the pressure is reduced in separator. Forced Circulation (FC) Evaporator is different from those Natural Circulation Evaporators which use the Density Differ as the main drive force for circulation. Forced-circulation evaporators offer the highest operational flexibility, since heat transfer, vapor-liquid separation and crystallization can take place in separate components by locating pumps outside of the evaporator or by using propellers as in propeller calandria units. Forced-circulation tubular evaporators. systems. The liquid is circulated through the calandria by means of a circulation pump, where it is superheated at an elevated pressure, higher than its normal boiling pressure. Forced Circulation Evaporator is a type of evaporator that requires the addition of a pump and additional controls. GEA is listed on the German MDAX and the STOXX® Europe 600 Index and also included in the DAX 50 ESG and MSCI Global Sustainability indexes. Forced circulation evaporators are especially indicated when the flow to be treated contains fouling substances, viscous liquids, crystals or other components preventing natural circulation. Hence in these evaporators the flow velocity in the tubes is kept very high. You can decide for yourself whether you want to allow cookies or not.

After evaporation, the liquid portion is pumped again to be resent to the exchanger. Stay in touch with GEA innovations and stories by signing up for news from GEA. Long operating periods – boiling/evaporation does not take place on the heating surfaces, but in the separator. Forced Circulation Evaporator Operation Force is used to drive the liquid through the evaporator tubes thus producing high tube velocities. flow velocity in the tubes must be high, and highcapacity pumps are required. Forced Circulation Evaporators are short tube evaporators and are ideally used when the boiling of feed liquid on the heating surfaces is to be avoided due to the salting and fouling characteristics of the liquid. The liquid is recirculated by a centrifugal pump through an external (or internal) heat exchanger at high velocity (3-5 m/s), heated by condensing steam (or water vapors). A forced circulation flash evaporator utilizes a circulation pump to create a large circulation stream, and a pressure-reducing device (typically an orifice plate) to allow for flashing of the hot circulating stream. With our multi-effect evaporators, the effects can be neutralized so that a triple or double effect can become a single effect. The circulating product is heated when it flows through the heat exchanger and then partially evaporated when the pressure is reduced in separator. A: Product B: Vapor C: Concentrate D: Heating Steam E: Condensate . Natural circulation evaporators are based on the natural circulation of the product caused by the density differences that arise from heating. Process. A forced circulation flash evaporator utilizes a circulation pump to create a large circulation stream, and a pressure-reducing device (typically an orifice plate) to allow for flashing of the hot circulating stream. As one of the largest systems suppliers, GEA makes an important contribution to a sustainable future with its solutions and services, particularly in the food, beverage and pharmaceutical sectors. Main Business and Markets Served Table 96. Higher liquid velocities and the lack of boiling in the heat exchanger tubes help to prevent the tubes from coating. Since liquid circulation is maintained, the flow velocity in the tubes and the liquid temperature can be controlled to suit the product requirements independently of the pre-selected temperature difference. Any evaporator that uses pump to ensure higher circulation velocity is called a forced circulation evaporator. France EvaporationZone industrielle A rue René Cauche59139 Noyelles Les Seclin Francetél.

At first, the introduction of a pump and a few added controls may increase the installation, maintenance, and operating costs. When it comes to which type of evaporator to use for a specific application, operators have a number of different options to choose from. The main components of a forced circulation evaporator are a tubular shell and tube heat exchanger (either horizontal or vertical), a flash chamber (separator) mounted above the heat exchanger and a circulating pump (Figure 3.4). Forced Circulation (FC) Evaporator is different from those Natural Circulation Evaporators which use the Density Differ as the main drive force for circulation. A plate-and-frame configuration employs special plates, with alternate product and heating channels. Forced circulation type of evaporators are recommended for the concentration of high viscosities solutions/slurries which have a tendency to crystallize or produce scales. Adequate hydrostatic head suppress boiling inside the tubes thereby reducing scaling in the tubes. The forced circulation evaporator is great for the following applications: The circulating pump ensures high speed in the exchange tubes, reduces the amount of deposits on the walls and prevents evaporation, thus the risk of over-concentration. When designing a tubular evaporator, one should evaluate the value of mechanical recirculation. TMCI Padovan Forced Circulation Evaporators Corporation Information Table 98.
