Abstract
The distance between the combustion nozzle and the pump of a waste oil heater can be significantly increased by using a positive displacement pump which is proximate to the reservoir and remote from the nozzle, contary to the usual positioning of oil delivery pumps. The pump, which is not pressure regulated, thus pushes oil to the nozzle at a constant flow rate regardless of oil pressure at the nozzle.
