Waste oil heater system

Abstract

A waste oil burner apparatus for improved control of the output flame of a waste oil burner, which includes a first waste oil supply conduit configured to receive waste oil; a supply pump operatively attached to the first oil supply conduit, and which is configured to receive waste oil from the first oil supply conduit and which pumps the waste oil into an intermediate oil conduit; a feed pump physically attached to heater or burner] operatively attached to the intermediate oil conduit to receive oil therefrom and to pump it to an oil feed conduit; and a waste oil burner with an atomization nozzle operatively connected to the oil feed conduit to receive oil and atomize the waste oil.

1 . A waste oil burner feed and control apparatus comprising: 
 a first waste oil supply conduit configured to receive waste oil;    a supply pump operatively attached to the first oil supply conduit, and which is configured to receive waste oil from the first oil supply conduit and which pumps the waste oil into an intermediate oil conduit;    a feed pump operatively attached to the intermediate oil conduit to receive oil therefrom and to pump it to an oil feed conduit; and    a waste oil burner with an atomization nozzle operatively connected to the oil feed conduit to receive oil and atomize the waste oil.    
   
   
       2 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the feed pump is located at or near the waste oil burner.  
   
   
       3 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the feed pump is located at a fixed pre-determined distance from the atomization nozzle of the waste oil burner.  
   
   
       4 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the supply pump is a positive displacement pump.  
   
   
       5 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the feed pump is a positive displacement pump.  
   
   
       6 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the feed pump is mounted to the waste oil heater.  
   
   
       7 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the feed pump is mounted to a burner at the waste oil heater.  
   
   
       8 . A waste oil burner feed and control apparatus as recited in claim.  7 , and further wherein the feed pump is integral with the waste oil heater.  
   
   
       9 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further comprising a waste oil supply tank configured relative to the first oil supply conduit such that waste oil in the waste oil supply tank is provided to the first oil supply conduit.  
   
   
       10 . A waste oil burner feed and control apparatus as recited in  claim 1 , and further wherein the intermediate oil conduit is a first intermediate oil conduit, wherein the feed pump is a first feed pump and the oil feed conduit is a first oil feed conduit, wherein the waste oil burner is a first waste oil burner, and wherein the waste oil burner feed and control system further comprises: 
 a second intermediate oil conduit;    a second feed pump operatively attached to the second intermediate oil conduit to receive oil therefrom and to pump it to a second oil feed conduit; and    a second waste oil burner with an atomization nozzle operatively connected to the second oil feed conduit to receive oil and atomize the waste oil.    
   
   
       11 . A waste oil burner feed and control apparatus as recited in  claim 1 , and wherein the supply pump is a higher RPM pump.  
   
   
       12 . A waste oil burner feed and control apparatus as recited in  claim 1 , and wherein the feed pump is a lower RPM pump than the supply pump.
