Product Name: Gestra KDL13 Product Brand: Gestra Product Code: KDL13 Product Artikel: Gestra KDL13
Description
The desuperheater KD...13 consists of a vessel with builtin nozzle arrangement for injecting and cooling superheated steam in a water bath. The KD...13 is suitable for all applications where an effective conversion of
superheated steam into saturated steam is required. The
desuperheater is available for different operating loads as
horizontal design KDL 13 or vertical design KDS 13. The
KD...13 is custom designed for each application and meets
essential thermodynamic requirements to achieve optimal
performance.
Function
Superheated steam at a max. temperature of 400 °C is introduced into a controlled system and injected through a nozzle
into a water bath where it is cooled down to the temperature of
the saturated steam. In passing through the water the superheat energy of the steam is given up to the cooling water, with
some of the cooling water being evaporized and entrained as
saturated steam. The steam content after the cooling process
is 98 %. The desuperheater features an integral water separator that prevents the cooling water from being carried along
into the steam line during peak loads. The level electrode
NRG ... or NRGT ... detects the cooling water level and an
electronic control unit ensures that the evaporized cooling
water is replaced by make-up water. The cooling water
at the required upstream pressure is fed into the lower
part of the desuperheater via a control valve or a solenoid
valve. If the temperature of the steam is very high the cooling
water must be heated up. The water-bath desuperheater is
the only steam cooling system that supplies saturated steam
over a control range of 0 – 100 %.
