PLANT FOR GAS-PULSE CLEANING OF HEATING SURFACES Russian patent published in 2012 - IPC F28G13/00 

FIELD: power industry.

SUBSTANCE: plant includes pulse chambers with exhaust nozzles, periodically acting igniters, mixers with gas and air supply nozzles, which have shutoff and control valves, automatic control device (ACD) connected via electric circuits to periodically acting igniters and shutoff and control valves. Plant is equipped with multi-channel distributor of gas-air mixture, cutout devices for protection of tube system against contaminated flue gases, which are provided for exhaust nozzles of pulse chambers, and monitoring, blocking and alarm device (MB AD), sensors for fixation of position of shutoff and control valves and air and gas pressure gauges connected via electric circuits to MB AD that is connected via electric circuits to ACD respectively, multi-channel distributor of gas-air mixture, which is connected via electric circuits to MB AD and ACD, as well as cutout devices connected via electric circuits to MB AD and ACD too.

EFFECT: higher reliability and safer operation of gas-pulse cleaning plant due to providing automatic monitoring of its operation; reduction of its overall dimensions.
