Heating System

Abstract

Provided is a system that may be used to heat a storage tank. In example embodiments, the system may include a storage tank, a channel in the storage tank, a burner in the channel, and at least one source tank configured to provide a flammable gas to the burner, wherein the burner is configured to generate heat within the channel to warm contents of the storage tank. Example embodiments also relate to a method of warming a DEF tank stored on a trailer

What we claim is: 
     
         1 . A system comprising:
 a storage tank;   a channel in the storage tank;   a burner arranged one of adjacent to the channel and in the channel; and   at least one source tank configured to provide a flammable gas to the burner, wherein the burner is configured to generate heat within the channel to warm contents of the storage tank.   
     
     
         2 . The system of  claim 1 , further comprising:
 a device configured to ignite a gas flowing out of the burner.   
     
     
         3 . The system of  claim 2 , further comprising:
 a valve between the at least one burner and the at least one source tank.   
     
     
         4 . The system of  claim 3 , wherein the channel has an open end and a closed end. 
     
     
         5 . The system of  claim 4 , wherein the channel has a triangular cross-section. 
     
     
         6 . The system of  claim 2 , further comprising:
 a temperature sensor in the storage tank.   
     
     
         7 . The system of  claim 6 , further comprising:
 a valve configured to control a flow of the flammable gas from the at least one source tank to the burner based on a temperature sensed by the temperature sensor.   
     
     
         8 . The system of  claim 7 , wherein the device is one of a spark generator and a pilot light. 
     
     
         9 . The system of  claim 7 , wherein the device is arranged adjacent the burner. 
     
     
         10 . The system of  claim 9 , wherein the flammable gas is one of propane and natural gas. 
     
     
         11 . A method of warming DEF stored in a DEF tank, the method comprising:
 opening a valve to allow a flammable gas to flow to a burner, the burner being arranged near or in a channel arranged in the DEF tank.   
     
     
         12 . A heating system comprising:
 a tube shaped body;   a channel extending from the tube shaped body; and   a burner at least partially in the tube shaped body, wherein the burner is configured to warm the channel.   
     
     
         13 . The heating system of  claim 12 , wherein the tube shaped body includes a flue configured to receive exhaust gas from the channel. 
     
     
         14 . The heating system of  claim 13 , wherein the channel has a substantially triangular cross-section. 
     
     
         15 . The heating system of  claim 14 , wherein the channel includes an air flow guide defining a path of air flow through the channel. 
     
     
         16 . The heating system of  claim 15 , wherein the channel further includes a flame dissipater connected to the air flow guide. 
     
     
         17 . The heating system of  claim 12 , wherein the body includes a wall having a first aperture and a second aperture wherein air may enter the channel via the first aperture and leave the channel via the second aperture. 
     
     
         18 . The heating system of  claim 12 , further comprising:
 a pilot light configured to light the burner.   
     
     
         19 . The heating system of  claim 12 , further comprising a temperature sensor. 
     
     
         20 . The heating system of  claim 19 , further comprising:
 a valve configured to flow gas to the burner based on a temperature detected by the temperature sensor.
