Energy

ING-GRAD took part in a number of complex electric power supply projects, among others the construction of wind power plants, biomass power plants, thermal power stations, construction and reconstruction of gas distribution network as well as other projects. The increasing investment into renewable energy sources in Croatia was the opportunity for the company ING-GRAD to establish itself in that line of business operations as well. Dedication and quality is what matters when projects as demanding as these are concerned.

HEP heat storage, Zagreb Cogeneration Plant

A heat storage plant is constructed within the Zagreb Cogeneration Plant. The heat storage is a steel tank of 24 m diameter and of 47.50 m to 50.12 m sheathing height. The foundation structure of the heat storage steel tank consists of a circular reinforced concrete slab leaning on 69 reinforced concrete piles. In plan layout, the piles are distributed in four concentric rings (circles). The foundation slab is of D = 27 m diameter and of d = 200 cm thickness. Under the steel staircase, the foundation slab has a rectangular overhang of plan dimensions of approx. 3.40 x 6.5 m that is leaning on 2 piles. All the piles are of 1 m diameter and of 20 m length. A pumping station and hot water pipeline posts of the new plant are also constructed within the plant. The pumping station building is a one-storey building, of rectangular plan shape of 20.36 m x 11.59 m dimensions, of 8.56 m total height, measured from the elevation of the arranged terrain. The hot water pipeline route connects the part from the new pumping station to the exiting block C and from the new pumping station to the heat storage tank.
