DEVICE TO DETECT THE FLOW RATE OF GASES FLOWING OUT OF A CHIMNEY OF A KILN FOR THE FIRING OF CERAMIC PRODUCTS AND KILN FOR THE FIRING OF CERAMIC PRODUCTS PROVIDED WITH SAID DEVICE

摘要

A device (12) to detect the flowrate of the gases flowing out of a chimney (11) of a kiln (3) for the firing of ceramic products having a suction device (9) which directs the gases present in the kiln (3) towards the chimney (11); and wherein said device (12) is housed inside the chimney (11) and comprises a casing (13) provided with an axis (L) and having a head portion (16); and at least one sensitive element (24) having an end portion (28) housed inside the end portion (16) and which is subjected to a temperature variation proportional to the speed of the out-flowing gas flow (F); and a cleaning device (29) to clean the sensitive element (24) wherein an element (30) movable along the first axis (L) is operated by actuator means (31) so as to slide on the end portion (28) and to remove the pollutants that have deposited there.
