Claims9
An oil-fired heating plant comprising a combustion chamber, an oil burner having a combustion air inlet, said oil burner being located in said combustion chamber, a cyclone means for trapping and collecting flue dust and means for cycling flue dust collected in said cyclone means back into said combustion air inlet of said oil burner.
A method of disposal of combustible flue dust from an oil fired heating plant comprising the steps of:
- (i) passing flue gasses containing combustible flue dust from an oil fired burner combustion chamber into a cyclone;
- (ii) trapping and collecting said flue dust in the cyclone;
- (iii) recirculating the collected flue dust to the air inlet of the oil burner;
- and (iv) injecting the flue dust into said air inlet, whereby the flue dust is burned in the heating plant.
