PSV water heater

 

Appointment

Heater network of water warms up the water in the thermal power plants and heating plants.
Heating component pairs, taken from the lines of turbines and boilers of low pressure.



Device


psv

Represents the heater, the water network, shell and tube heat exchanger of vertical type, the main components of which are: housing, pipe system, the upper water camera, lower water camera.


Pipe system - made of brass, stainless steel.
Tube bundle psv - it is possible to manufacture separately.

Heater psv supplied in assembled form supplied on a valve and instrumentation in accordance with the workers'drawings and specifications.

Principle of operation

In heaters network water moves through the tubes, and heating steam enters the inter-tube space. Heating steam condensate drains in the lower part of the body and is discharged from the boiler through the valve, controlled by an electronic control device.

Manufacturing

Heater psv is made to order in the shortest agreed terms.

Send

Heater network of water leaves on wooden bars, attached to the floor platform in accordance with the installation drawing.

Designation

PSV 200-7-15- heater network of water, vertical type with the heating surface of 200 sq m, a maximum pressure of working a couple of 0.7 Mpa, maximum water pressure in the pipe system is 1,5 Mpa.

psgNetwork water heaters - PSG

Network water heaters, heaters PSG - horizontal heat exchangers psg

surface type with the enclosures of all-welded construction.

Network water heaters contain the tube bundle of the surface which is formed by the direct brass pipes, expanded in the pipe boards.

To avoid damaging the pipes, elimination of hazardous forms of vibration in the network water heaters installed intermediate partitions.

Heating steam enters the heaters of the district heating steam extraction turbines and condenses on the surface of the pipes beam, inside of which are leaking and there is a heat the water network.

Steam pipelines to the body are connected through a special cone, inside of which are concentric dividers. The dispersion of the pair on the length of the machine, use two connections, in conjunction with input devices ensures a uniform distribution of steam on the surface, that with great efficiency use of network water heaters.

Heating steam condensate from the surface of the pipe is in the lower part of the body and then to the siphon. Are special nozzle with high flow rates with runoff condensate and low flow side. This is limited admission to secondary steam heaters, formed in конденсатосборнике from boiling situated therein condensate at the discharges load of the turbine, thus providing its protection from a possible acceleration of this steam.

Protection of the heating surface of tubes from erosion by the input pair is installing in the first row of the beam steel tubes in them is not the network of water.

Heaters have a compensation of thermal expansions of pipes due to installation of double-lens compensators.

Network water heaters are designated in the following way:

PSG-800-3-8-I, where

PSG - heater network of water horizontal version,

800 - surface heat transfer to the external diameter of pipes, m2,

3 - maximum operating pressure of heating steam, kg/cm2 abs,

8 maximum operating pressure of the network of water, kg/cm

I - modification of the device.
