摘要

A method of automatic gas-impulse cleaning the heating surfaces of the convection chambers neftenagrevatelnyh furnaces comprising condensate removal from the damper and of each line plameprovodov, purge plameprovodov air with a predetermined interval of time, purge gas supply pipe, filling the pulse chamber gas-air mixture, the implementation of high-voltage discharge with a time interval sufficient to filling the pulse chamber, exercise blasts pulsed gas mixture in the chambers at predetermined times and predetermined nnym time interval, characterized in that the removal of condensate from the damper assembly preparation and ignition mixture disposed above the pulse chambers, and all plameprovodov occurs simultaneously and continuously to avoid condensation in the damper and plameprovodah, wherein the first opened electrically driven valve in the gas line, and after its complete opening into operation and the fan blowing is carried out simultaneously all plameprovodov air for a predetermined time, the electromagnet opens pleasing valve in the gas supply line and for a predetermined time is carried out simultaneous filling of all pulse chambers gas-air mixture, and then starts to supply high level at a time interval sufficient for the simultaneous filling of all pulse chambers and gas mixture, an explosion-gas mixture simultaneously in all pulse chambers and when reaching a predetermined number of explosions stops the gas-impulse purification.
