Combustion chamber – fire tube — and boiler housing have a cylindrical shape. Convective heating surfaces are formed by second and third pass flue tubes, located axisymmetrically around the combustion chamber. The two-three-row arrangement of the second pass flue tubes provides a high heat transfer rate, increasing the boiler efficiency.

The completely flower-round first reversing chamber is formed by the rear tube wall and the torispherical head. The second reversing chamber is formed by the front tube wall and the recess of the boiler front door lining, made of special design according to the burner type. The boiler front door can fully open with the burner installed in any direction.

With the front door open, the easy access to the combustion chamber and flue tubes is provided for maintenance and cleaning of the boiler. Inspection and cleaning of the first reversing chamber are carried out through the combustion chamber. Water inlet and outlet nozzles, as well as emergency line nozzles are located on the top of the boiler. TERMOTEKHNIK type ТТ115 boilers have two emergency line nozzles. A water-guiding element is installed under the water inlet nozzle, ensuring the most effective internal boiler heating medium distribution.

Three-way boiler gas flow with low heat density of the combustion chamber ensures easy set-up of the boiler combustion modes and minimizes the harmful combustion products emission. Low aerodynamic resistance of the boiler ensures optimal selection of the burner.

Installation of the first reversing chamber of the boiler on the same supporting-sliding or rigid (for boilers above 8.0 MW) anchor of the boiler furnace structure ensures compensation for cyclic thermal stresses and, thereby, long service life of the boilers.
