(Descending) Steam Accumulators

In case of fluctuating steam demand or to cover highest consumption of steam we recommend a steam accumulator.

In connection with our HSK Quick Steam Generator installation of feedwater pumps is not necessary. When starting the system the steam accumulator will be filled with water by the feedwater pump of the steam generator. The steam produced by the steam generator is introduced into the steam accumulator by means of an injector. The water will be heated to working temperature and pressure.

The extraction of the steam is carried out by a steam valve into the steam tube system of the plant.

Water Steam Separator

DThe water steam separator is used for drying and cleaning of the saturated steam. In this vessel the specific heavy particles like condensate, suspended humidity, boiler sludge etc. will be separated from the specific lighter steam.

When starting the quick steam generator first some amount of water is obtained before the steam production will start. The water steam separator is extracting this water. This guarantees a sufficient flow rate in the tube system of the quick steam generator, on the other hand this vessel prevents from steam impacts in the outer steam tube system.

Feedwater and Condensate Tanks/ Deaeraters

These tanks are manufactured from stainless steel 1.4301 serving for collection of feedwater or condensate.

Delivery including all necessary armatures and fittings. Sizes up to content 3.000 liters. Special sizes on request.

Water Treatment

For the operation of a quick steam generator proper treated feedwater has to be used. The feedwater in it's quality must be according to the TRD or VdTUEV-instructions.

The water treatment units are working according to the Na-ions exchange procedure.

In addtion to this procedure, the feedwater has to be alkalized with chemical substances in a dosing unit. These chemicals ensure further softening of the feedwater and prevent the tube system from oxygen and carbonic corrosion.
