Flue Gas Desulphurization Plant Project on TENT B

Works on Flue Gas Desulphurization (FGD) Plant at Thermal Power Plant Nikola Tesla B are in progress.

Manufacturing and erection of Pipe and Cable Racks’ elements are executed in the amount of 600 t and length over 1 km. Pipe and Cable Racks support pipelines used in the flue gas desulfurization process as well as electrical installations.

We manufacture and erect Support Steel Structures in the amount of 1.100 t as well as Flue Gas Ducts amounting to 1.800 t, which are 10.1×10.1m in size and are installed at +18m and +30m elevations.
At the same time, work is progressing on the installation of ball mills for Limestone Mill, three (3) ball mills have been installed. The weight of one ball mill is 85 t.

The flue gas desulfurization project TENT B will reduce the emission of sulfur dioxide and particles by 96%, from 80,000 tons per year, to 4,500 tons.

Kostolac B - Construction of the Heavy Oil Tank R3000

Upgrade of Iron Gate Đerdap 2

Goša Montaža takes part in the project  Đerdap 2 – Upgrade of Iron Gate 2 Navigation Lock as a partner of DSD NOELL GmbH. Upgrade of Iron Gate 2 Navigation project aims at improving the navigation on the Danube, which is one of the most important waterways in Europe.


Iron Gate 2 Navigation Lock in Đerdap 2, due to outdated equipment and damaged structure needs an update and rehabilitation. The works in Goša Monaža scope include the following: preparation of design, disassembly, manufacturing and assembly of 3 new cranes with a capacity of 40 t, lower head service mitre gate, upper head service gate, safety net and trash racks as well as upgrade of discharge and drainage system. Besides stated, Goša Montaža will perform the works on drainage and erection of the new upper head service gate which is delivered by DSD NOELL GmbH.

The preparation of design will start immediately, while the works on the site should start in October 2022, with the dismantling of one of the three cranes and the installation of one new crane. The estimated duration of the works is until March 2024.


This project will be financed by European Investment Bank (EIB) loan (60 % ) while financing of other 40 % is secured through CEF Fond (Connecting Europe Facility Fund).

Unit B1 revitalization of TENT B

In the revitalization of Unit B1 of TENT B, Goša Montaža is performing erection works on the installation of a new RA stem pipelines, superheater P4, which require the highest quality of welding works, separators, as well as works on installation of combustion grate and flue gas duct expansion joints.


We are proud to highlight that we are part of the largest revitalization project of the Thermal Power Unit in Serbia, which, regarding scope of works, exceeds all former overhaul since the Unit B1 was put into operation. The scope of works undertaken by Goša Montaža is considered to be the highest responsible segment of works on the most significant part of the boiler equipment.


On the revitalization project up to 200 production workers were deployed, all of them with dedication and commitment contribute each and every day to the successful finalization of the Unit B1 Overhaul Project before the set deadline, aware of the fact that each day counts, and each day saved means a lot for the stability of the power supply system of the entire Serbia.

Flue Gas Desulfurization Plant Project on TENT A IS IN ITS FINAL STAGE

Photos and a short film shows the final erection of the primary steel structure of the Wet Stack for Absorber C1. Works are being carried out at a height of 138m within the FGD project on TENT A.

Flue Gas Desulfurization Plant on TENT A

We have been assigned an important role in the project of constructing a FGD Plant in TENT A, where we have been entrusted with mechanical work on the new plant.


At TENT A we are progressing with the works on FGD Plant. The expert teams of Goša Montaža are currently engaged in the erection of the absorber, BAF erection, as well as the spray header pipeline erection.


The importance of this project is reflected in the significant reduction of SO2 emissions in accordance with environmental regulations as well as in compliance with the application of standards aiming at environmental protection.
