## Abstract

Disclosed is a novel method for cleaning an electrostatic precipitator by directing a stream of cleaning gas through a flexible tube positioned inside the electrostatic precipitator. The stream of gas causing the flexible tube to move randomly directing the stream of gas at the precipitator plates with sufficient force to dislodge particles adhered to such plates.

## Claims

### Claim 1

A method for cleaning an electrostatic precipitator comprising:
causing a flow of cleaning gas through at least one flexible tube positioned inside the precipitator housing, wherein said flow of gas is sufficient to cause the flexible tube to move about randomly thereby directing said flow of gas onto the electrostatic precipitator plates and further, said flow of gas being sufficient to cause particles which have adhered to said precipitator plates to be dislodged.
