TKU-E boilers are flue fire-tube, two-tensile, large-capacity boilers determined for the combustion of liquid and gaseous fuels. The combustion chamber size is designed so as to minimize emissions. The design pressure of KU line boilers is 0,6; 1,0 or 1,6 MPa. The boilers are supplied on a standard frame, including insulation with sheeting and a service platform. The supply includes the respective fittings. The boilers are equipped with economizers (eco). It is possible to place behind the boiler condensate exchangers, which utilizes the vapour heat included in the flue gas. The design, manufacturing, testing and additional equipment of boilers are done according to the CSN technical standards.
