The Plate Evaporators are also known as the gasketed plate and frame evaporators. In the centre of the cylinder there is a steam heating section, with pipes passing through it in which the evaporating liquors rise. Thus, we have a variety of types of evaporators, such as prime surface types, finned tube or extended surface type, shell and tube liquid chillers, etc. At the top of the cylinder, there are baffles, which allow the vapours to escape but check liquid droplets that may accompany the vapours from the liquid surface.

The Plate Evaporators are also known as the gasketed plate and frame evaporators. In the centre of the cylinder there is a steam heating section, with pipes passing through it in which the evaporating liquors rise. Thus, we have a variety of types of evaporators, such as prime surface types, finned tube or extended surface type, shell and tube liquid chillers, etc. At the top of the cylinder, there are baffles, which allow the vapours to escape but check liquid droplets that may accompany the vapours from the liquid surface.

The Plate Evaporators are also known as the gasketed plate and frame evaporators. In the centre of the cylinder there is a steam heating section, with pipes passing through it in which the evaporating liquors rise. Thus, we have a variety of types of evaporators, such as prime surface types, finned tube or extended surface type, shell and tube liquid chillers, etc. At the top of the cylinder, there are baffles, which allow the vapours to escape but check liquid droplets that may accompany the vapours from the liquid surface.

Basket-type Vertical Evaporators 2.3. In this type of evaporator, the liquid flows as a thin film on the walls of long (from 12 to 30 feet in length) and vertical heated tube. Tube length usually varies from 20 to 65 ft. The type of equipment used depends largely on the method of applying heat to the liquor and the method of agitation. %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz��������������������������������������������������������������������������� Email. The main advantage of this type of evaporators is higher heat transfer rate. endstream
Evaporators are also used in oil fields to separate water and various other compounds from crude oil. Basket-type Vertical Evaporators It is very similar to those of the standard evaporator except that the down take is annular. While they are natural-circulation evaporators, they are also … The main advantage of this type of evaporators is higher heat transfer rate. 0000009478 00000 n
