Coolers condensate OG-130 are used for cooling the steam condensate heaters PN (low pressure) and PSV heaters (mains water) heating systems connected to CHP plants and industrial boilers. Heat which is released 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-130
Chiller condensing type OG-130 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 pipe system and removable front and rear cameras or caps. The body of the cooler condensate OG-130 is composed of steel tubes that are connected by pipes through which the condensate flows from one body to another. These pipes also serve as supports for the top row of blocks. The longitudinal bulkhead in each hull provide two turns of the condensate annulus. The pipe system chillers condensate OG-130 consist of two steel tube sheets with Cavalcanti they straight tubes 22х2. The front plate is tightly welded to the housing and is stationary and the rear movable with Salnikov seal. Front water chamber runs cooler drainage OG-130 runs out of pipes, flanges and flat bottoms. When disassembling the camera all of the cameras are removed at the same time. Inside the chamber separated by a partition providing two zod condensate annulus. Chassis covers cooler condensate made from stamped elliptic bottoms and flanges.
