Coolers condensate OG-24 used for cooling the steam condensate heaters PN (low pressure) and PSV heaters (mains water) heating systems connected to CHP plants and industrial boilers. The heat produced during the cooling of the steam condensate is used to heat more cold main condensate in the regeneration system of the turbine, saving heat in a cycle.
Note that the PC-boiler has the ability to produce modernized steam-water heaters with built-in cooler condensate!
The principle of operation and arrangement of chiller condensate OG-24
Chiller condensing type OG-24 is a heat exchanger "water-water" the horizontal type, which consists of 4 sections, which use countercurrent movement of the liquids. The cooler section of the condensate consists of a body of the pipeline system and removable front and rear cameras or caps. The body of the cooler condensate OG-24 consists of steel pipes, which are connected by pipes through which the condensate flows from one body to another. These pipes also serve as supports for the upper row of blocks. Longitudinal bulkheads in each hull provide two turns of the condensate ring. Pipe system chillers condensate OG-24 consists of two steel tube sheets with Cavalcanti they straight pipes 22х2. The front panel is securely welded to the housing and is stationary and the rear movable with Salnikov seal. The front water chamber, works the drain cooler OG-24 tracks of pipes, flanges and flat bottoms. When disassembling the camera, all the cameras shot at the same time. Inside the chamber separated by a partition providing two zod condensate in the annular space. Chassis cover cooler condensate made of stamped elliptic bottoms and flanges.
