OPERATING METHOD OF HEATING CATALYST Russian patent published in 2016 - IPC F01N3/20 F01N9/00 

FIELD: heating; machine building.

SUBSTANCE: invention relates to operation of the device for cleaning exhaust gases (EG). Method of operation of the device (1) for cleaning exhaust gases (EG) with electric heater (2) for heating of at least one gas flow or surface (25) in the device (1) for cleaning of EG and with the attachment point (3) supply to feed additive in the device (1) for spent gas cleaning, so that additive falls on the electric heater (2) with the following steps: a) supply of additive in the area (3) supply; b) determination of the working state (4) of the device (1) for spent gas cleaning, in which electric heater (2) may occur deposits based on at least one parameter (5) state; c) determination of clock frequency (6) depending on operating conditions (4), if the determined at step b) an operational status (4) is in a given range (7) operating conditions; d) step-by-step activation and deactivate electric heater (2) with a certain clock frequency (6), if the determined at step b) an operational status (4) is in a given range (7) operating conditions.

EFFECT: effective prevention of formation of deposits on the heater and removal without the need to use excessively large number of heating power.
