AUTONOMOUS DE-ICING SYSTEM OF THE GAS TURBINE UNIT AIR PURIFIER (OPTIONS) Russian patent published in 2023 - IPC F02C7/47 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to de-icing systems of air purifying devices of gas turbine units (GTU). The system contains an air heating unit located in a free-standing housing connected to a gas turbine unit. The air heating unit contains the first air path connected by distribution ducts to the hot air supply inputs to the air purifier of the gas turbine unit. The air heating unit contains a second air path for heating the production premises of a gas turbine unit. Each of the air paths contains inlet lines with blow-out fans with check air valves installed on them. Behind the fans, in the course of the air flow, there is a first duct connecting the first and second heating paths and equipped with a controlled air valve. In each path of the line, a non-return air valve and heat exchange units are located behind the first connecting duct. Behind the heat exchange units, in the course of the movement of air flows, there is a second air duct connecting two air heating paths and equipped with a controlled air valve. Each path contains two output lines and their corresponding output windows in the housing for connection to the distribution ducts. In the first air path, before the point of its separation into two output lines, a controlled air valve is installed. In the second heating air path, a controlled air valve is installed on one of the two output lines.

EFFECT: expansion of the functionality of the autonomous de-icing system of the GTU is achieved with the possibility of regulating heating modes.
