METHOD FOR CLEANING OF EXHAUST GASES OF GAS-TURBINE PLANT AND DEVICE FOR ITS REALISATION Russian patent published in 2008 - IPC B01D53/92 B01D53/60 

FIELD: technological processes.

SUBSTANCE: method for cleaning of exhaust gases of gas-turbine plant (GTP) includes installation of thermocatalytic neutraliser (TCN) in gas flue of GTP with developed catalytic surface in the form of panels, total area of surfaces of which, located cocurrently to direction of exhaust gases motion, exceeds area of cross section of GTP gas flue, at that TCN is installed in vertical gas flue of GTP, and required total volume of TCN panels is defined using the following expression: v_k=B_e.g.·τ, where: v_k - required total volume of TCN panels, m³; B _e.g. - volume flow rate of exhaust gases, m³/s; τ - required time for contact of exhaust gases with developed catalytic surface of TCN based on necessary extent of GTP exhaust gases cleaning, s. Device is suggested for cleaning of gas-turbine plant (GTP) exhaust gases, which includes thermocatalytic neutralizer (TCN), which is arranged with the possibility of installation in GTP gas flue along direction of exhaust gases motion and which represents casing open on top and bottom, inside of which panels of TCN catalytic units are installed as inclined in respect to vertical axis of casing and gas flue of GTP and are serially connected between each other, converging in adjacent top and bottom ends. Panels are made on the basis of highly porous cell materials, at that panels of catalytic units of TCN are formed by frame with wing spars, in which holders are inbuilt with catalytic units.

EFFECT: reduction of hydraulic losses in thermocatalytic neutraliser and required volume of catalyst, increase of extent of exhaust gases cleaning, compactness and manufacturability of layout of device for cleaning of exhaust gases of gas-turbine plant.
