Steam boiler / fire tube / heat recovery

Waste gas heat recovery boilers downstream cogeneration and industrial plants.
This kind of boiler employs the heat of exhaust gases to produce steam.
Traditional gas heat recovery boilers do not have a furnace, as the water inside them is not heated up with a burner, but just with the heat of fumes
conveyed in them.

Steam boiler / fire tube / heat recovery

Waste gas heat recovery boilers downstream cogeneration and industrial plants.
This kind of boiler employs the heat of exhaust gases to produce steam.
Traditional gas heat recovery boilers do not have a furnace, as the water inside them is not heated up with a burner, but just with the heat of fumes
conveyed in them.
The fields of applications are:
- INDUSTRIAL PROCESSES
- ENERGY PRODUCTION PLANT
- COGENERATION
- BIOMASS PLANT

An big innovation is the introduction of a waste heat recovery boiler able to combine the generation of steam by combustion with heat recovery from hot fumes from external sources. This free source is primary, while combustion can be used as a backup or provide the power required if the recovery fumes are not enough to meet the systems request for steam. Combustion-based operation features three flue-gas pass with passing flame and wet bottom. The boilers body is made with flanged tube plates that replace the more traditional corner welds to ensure top safety levels and reduce areas with thermal stress. The recovery section is entirely
separated from the combustion section, though it is immersed in the same boiler water. The front doors are secured to the boilers body with double jointed hinges, which are used to open and inspect the equipment with no need to remove the boiler.

ECONOMIZER
No need to mention again that such as for the traditional boiler, it is possible to increase the efficiency up to 5% with the installation of an economizer, to preheat the feed-water with the fumes.

Steam boiler / water tube

The Water Tube Boilers are used to meet high capacity and high pressure steam demands processes in industrial processes. These boilers are produced under German Eckrohrkessel GmbH license.

They are manufacture in accordance with TSE 377, EN12952 standards, tested and CE marked as per EN 97/23/EC pressure vessels directive and module B+F, designed, manufactured and tested according to ASME Section I and S stamped. Water Tube Boilers are designed as D or O type with bi-drum or single drum for generating up to 80 bar pressure and 150t/h of saturated or super-heated steam.

These boilers can easily handle load fluctuations without changing pressure and temperature. They engage regimes quickly and are more resistant to thermal stress because of their design which has a low water volume.
Design:
Water Tube Boilers are designed according to EN 12952 , ASME section I or other standards depending on customer s request. The termal design and water circulation of boilers are provided by German Eckrohrkessel GmbH company that we are licensor, strength calculations and design details are made in Selnikel.

Boiler Features:
In single drum(O type) corner tube boilers that designed with Eckrohrkessel GmbH company license, steam and water begin to be separated in the upper steam overflow headers. The steam dryness is vey high and no water drift happens. Even though feed water purity is poor, steam is obtained in high purity.

In bi-drum(D type) boilers, combustion chamber and evaporator tube bundle through the membrane wall tube around them, respond very quickly to load demands. Circulation and water drift problems are eliminated by the special drum internal parts.
