Claim:
1. A fabric filter system, comprising: a first fabric filtering device in the form of an elongated tubular fabric bag; a first gas tank configured to provide compressed gas; a first pulsing gas duct fluidly connected between the first fabric filtering device and the first gas tank with a first pulsing valve arranged in the first pulsing gas duct between the first fabric filtering device and the first gas tank for compressed gas flow from the first gas tank through the first pulsing valve and the first pulsing gas duct for cleaning the first fabric filtering device; a second gas tank configured to provide compressed gas; a second pulsing gas duct fluidly connected between a second fabric filtering device and the second gas tank with a second pulsing valve arranged in the second pulsing gas duct between the second fabric filtering device and the second gas tank for compressed gas flow from the second gas tank through the second pulsing valve and the second pulsing gas duct for cleaning the second fabric filtering device; and a control valve arranged between the first gas tank and the second gas tank thereby fluidly connecting the first gas tank and the second gas tank when the control valve is opened, and fluidly isolating the first gas tank from the second gas tank when the control valve is closed; wherein the first pulsing valve is configured to be opened to introduce the compressed gas into the first fabric filtering device via the first pulsing gas duct to clean the first fabric filtering device while the control valve fluidly connected to the second gas tank remains open for a predetermined time before closing.
