METHOD OF AUTOMATIC GAS-PULSE PURGING OF HEATING SURFACES OF OIL-HEATING FURNACE CONVECTION CHAMBERS Russian patent published in 2009 - IPC F28G7/00 

FIELD: heating.

SUBSTANCE: invention relates to the field of power technology immediately dealing with a method of heating surfaces automatic gas-pulse purging. The proposed method envisages the following operations: condensate removal from the damper surface as well as from each flame conduit line; the flame circuit blow purging at specified intervals of time; the gas supply conduit blow purging; filling the pulse chambers with gas-and-air mixture; generation of high-voltage discharges at intervals of time sufficient for the pulse chambers filling; generation of a specified number of gas-and-air mixture explosions in the pulse chambers at specified intervals of time. Removal of condensate from the damper of the mixture preparation and ignition unit positioned over the pulse chambers and from all the flame conduits proceeds simultaneously and continuously to prevent condensate formation, the sequence of operation thereby being as follows: the gas supply line motor operated valve is opened; the blower is actuated to provide for simultaneous air blow purging of all the flame conduits during a specified period of time; the gas supply line solenoid-operated valve is opened; all the pulse chambers become simultaneously filled with gas-and-air mixture within a specified period of time; high-voltage discharges are generated at intervals of time sufficient for all the pulse chambers simultaneous gas-and-air mixture filling; gas-and-air mixture explosions are simultaneously generated in all the pulse chambers; the specified number of explosions having been generated, one discontinuous purging.

EFFECT: operational reliability improvement due to condensate continuous removal as well as provision for attaining the specified pulse chambers pulse wave capacity.
