Site: TPP “Maritza East 3”
Sub-site: Flow optimisation of the air heater, Units 2 and 4.
Main characteristics of the site:
The elaboration is in conformity with the technological decision of Prof. Dr.-Ing. H. Ruscheweyh and the report of Mr. Mayr.
Numerical evaluation: the inhomogeneous flow of the flue gas in the cross section of the flue gas duct, the flow separation of the flue gas, which reaches each of the four inflow hoods, the temperature differences, result of the inhomogeneous distribution of the flue gas in the inflow hood to the air heater bundles, fly ash settlement.
According to the data provided in the test report of the tests, a satisfactory homogeneous flow distribution in the cross-section of the flue gas duct and to the four inflow hoods can be achieved by introduction of additional devices.
Flow dispenser devices with specific form are projected. Such devices shall be mounted in a certain order, considering the number of devices required and distance in between, and most importantly, the angles to the axis of the flue gas ducts.
Owner: CONTOUR GLOBAL Maritza East 3 PLC
