TEMINOX TGL 35 - 100
Duoblokové horáky s tlakovým rozprašovaním
Procedure and Operation
- A special feature of the TEMINOX system is that for the first time burner and furnace have been combined within an industrial application. The system consists of the TEMINOX burner and the TEMINOX reaction chamber where proper combustion takes place. Thus, the furnace is part of the system. Due to this optimal alignment of burner and furnace, the TEMINOX system does not depend any longer from the make and type of the heat generator.
- The combustion air is divided into two partial flows: The primary air flows in swirled form to the furnace centre. The secondary air is fed to the combustion process by means of nozzles that are specially adapted to the furnace and the reaction chamber. Thereby the flue gas recirculates between the flame tube and the TEMINOX reaction chamber; the flue gas emits heat to the flame tube and simultaneously cools down the reaction chamber. The intensive mixing of all material flows at excellent flame quality is safeguarded by the extremely swirled primary air and by guided secondary air jets. Thus, any temperature peaks are avoided.
- This is a basic condition for achieving ultra low NOx emissions. In the reaction chamber, the combustion process takes place under controlled conditions with high energy density. In contrast to conventional firing systems, due the good temperature profile in the reaction chamber a uniform heat stream density is reached within flame, thus the tube is less stressed.
Air and Fuel Guiding System
- The burner is equipped with an electronic compound regulator. The air streams (primary and secondary air) air guided to the combustion process by means of three different air dampers. Using a return oil pressure atomiser, the fuel oil is brought to the furnace via nozzles, whereas the fuel gas leaves the concentric gas gun with removable gas nozzle towards the furnace.
Reaction chamber
- The reaction chamber consists of a cylinder and the bearing unit with bearing rings and feet. These are made of special highly-alloyed austenitic steel that is resistant against high temperature corrosion, brittleness and scaling at temperatures ranging between 900 and 1,000 °C. The cylinder is supported axially shiftable in the bearing rings, thus it may expand freely without any heat tensions. The lower part of the bearing unit is supported on the flame tube. At the flame tube, no holding or other fixing elements are required. In the reaction chamber, the controlled reactions described above take place that ensure a uniform temperature profile, not depending upon furnace load.
