Abstract
A helical coil of tubing is disposed in a cylindrical tank in spaced relation thereto so as to act as a baffle for the products of combustion introduced thereinto by creating a tortuous passageway in said tank. The helical coil has its end portions arranged in spaced parallel sections defining supporting skids extending longitudinally of the helical coil and thereby supporting the same in said tank. The tank is positioned in a secondary larger cylindrical tank and the fluid to be heated, such as oil, is circulated through the helical coil, the skid-like parallel communicating portions thereof forming the supports and in the area between the tanks to obtain a highly efficient heat transfer.
Claims5
A horizontally disposed cylindrical shaped baffle for use in a heater and the like in which liquids are heated, said baffle comprising a single helical coil of tubing, the convolutions of which are vertically arranged in side by side engaging relation and having straight sections of tubing communicating with said helical coil of tubing at the opposite ends thereof and extending in spaced parallel relation to one another on the outer side of and in supporting relation to said engaging convolutions of tubing forming said helical coil.
