T-600 oval chimney liners are used to discharge smoke from solid fuel devices, where the continuous working temperature of smoke does not exceed 600°C.

This system enables the modernisation of the boiler rooms and adapts old chimneys to the new working conditions. It is used in a rectangular section flue. Its shape enables it to be fitted perfectly to the existing flue and to make the maximum use of space.
The system consists of smooth-walled pipes and moulded parts made of high-alloy stainless steel, steel type 1.4404, resistant against intercrystalline corrosion.
All elements are plasma-welded with a longitudinal seam weld. Due to the rapid warm up of the thin-walled batch pipes, they ensure high expansion that prevents the formation of condensation in the furnace’s initial start-up phase. Heat losses, resulting from the cooling of the heat source during the starting of the furnace, is reduced by rapid cooling, which leads to fuel saving and reduces the adverse effect of the furnace environment.
