is generated while the heat of the flue gases is fed, through hot-water furnaces, into the district heating system.

The stack of the heating plant was built by the general contractor Heat Technologies Co. under the supervision of the main contractor Vegyépszer in 1974-75. The monolithic reinforced-concrete body of the stack was made by ÁÉV No. 31 with sliding-shutter technology. The chimney consists of a tapering, quadratic-parabola section up to the hundred-meter mark, from where it further narrows by one centimetre per vertical metre. The body has a wall thickness of 30 centimetres up to the 40 metre level, from where it gradually decreases to 20 centimetres.

Combustion gases are exhausted from the furnaces at the bottom into the chimney body through two flues, one with a 2,500-millimetre and another with a 1,400-millimetre diameter. The smokestack body could accommodate four flues, which means that two more could be added. These were meant to exhaust flue gases produced in the furnaces that were to have heated the housing estates that remained on the designers’ drawing boards. The sheet metal flues inside the chimneys are attached
