Saving Resources through the highest possible efficiency!

Steam generation and emission-free district heating are important components of power plant technology for an efficient production of energy. Engineering Dobersek GmbH also contributes to the growing demand for steam and hot water generating installations. Apart from turnkey boiler houses, Engineering Dobersek GmbH is in the position to supply upgrades for existing plants as well as renovation and refitting of plant sections - as specifically required by the customer.

The boiler is the first component of each hot water-, steam- and energy generation process. The boiler house mainly consists of the boiler with flue gas duct and chimney as well as the primary and secondary water circuit. Water treatment plays a major role as well. Highest efficiencies can be achieved through optimizing design of the boiler plant in regards to fuel type and operational mode. Low losses during energy conversion in combination with the highest possible heating (furnace) efficiencies provide an economical and ecological operation with state-of-the-art-technologies. .

In der Wasseraufbereitung und der Wasserkreislaufführung reicht unser Einsatzspektrum von der Aufbereitung von Oberflächen- oder Brunnenwasser als Kühlwasser über die Kesselspeisewasseraufbereitung und Erzeugung von Reinstwasser für die Halbleiterindustrie. Dabei werden konzeptionell alle marktgängigen Verfahren und, wenn notwendig, auch Sonderapplikationen berücksichtigt.

In water treatment and the water circuit guiding the supply of ENGINEERING DOBERSEK GmbH includes the treatment of surface water or well water as cooling water to the boiler feed water treatment and the generation of ultra-pure water for the semiconductor industry. Thereby all marketable processes and – if required – customer-specific applications are conceptually considered.

Advantages of Turnkey Boiler Houses by ENGINEERING DOBERSEK – boilers are designed according to your requested burning material:

  • Design based on burning material, medium and mode of operation.
  • Adaptation of the boiler to the plant in respect of heat circulation, environmental compliances and construction conditions.
  • Wir wählen Dimensionierung und Werkstoffqualitäten nach Beanspruchung und thermischer Belastung der Anlage.
  • Dimensioning and choice of quality materials according to thermal and other stresses. Constructive layout considering the highest possible elasticity for absorption of thermal stress.
  • Maximum heat exploitation by water-cooling of parts in contact with flue gas and reduction of radiation losses to a minimum. .
  • Flue gas overpressure operation and dimensioning of fire tube aligned to the heating conditions lead to perfect burning and thus to the highest possible heating efficiency.
  • Low loss factors in combination with a low self-energy demand and operation promoted by the latest state-of-the-art technology. Robust and economic construction.

Water Treatment

Due to heating or water evaporation in the boiler, salts contained in natural water may increase, and depending on their nature (iron, manganese, magnesium, calcium, sodium, etc.) they can cause various different malfunctions or damages. Corrosion is one of the effects on the boiler when using untreated water. Another disadvantageous effect is sedimentation of enriched salts on the pipe and boiler walls. Thermal conduction is therewith reduced and boiler efficiency decreases drastically.

Also the material installed in the plant is subjected to more stress and wear. As a result, one risks extremely shortening the boiler´s working life and thus high repair and maintenance costs together with necessary new reinvestment costs. In order to avoid this damage, there is no way round the integration of a water treatment plant designed for its special field of application. ENGINEERING DOBERSEK GmbH offers alternatives for all kinds of applications.
