Photos of Tire Vaporizing Units in St. George, UtahDigital photographs taken by Lynn Bishop of Manti, August 24, 2002.. The photographs are of two tire vaporizing units. Neither are currently in use. One was in used for a year in Boise, and needs to have the ceramics replaced in the secondary burner, to withstand the 3500 degree Fahrenheit temperature. The other is newly built (within past year) but has not been put into use yet. The completed unit will have a tertiary burner as well, at which point dried sewage will be added and incinerated; and then the emissions, combined with water to cool them, gaining added thrust from the steam, will be sent into a turbine, which will run a generator to create electricity. Click here for description of how the completed unit will work.
The black vertical cylinder on right is the tire burning chamber for the older unit. The jet engine shaped burner on the left is of the newer secondary burner. Combined, this photo gives a rough visual image of what the primary and secondary burners will look like when joined together.
Here is a full picture of the older unit (black in color), with just a little of the newer unit shown on the left (rust colored, because of rust on unpainted finished surface).
Older unit controls between primary burner (right, dark) and secondary chamber (left, blue/rusting). The horizontal chamber is where the vapor from the tires passes (right to left). The unit coming in from the top right toward the center is the pre-heating chamber where the waste-oil is burned and injected into the chamber to pre-heat the chamber at 1400 degrees F. This is only run when starting up the unit. The vapor then ignites and burns at 3500 degrees F in the secondary burner (left). In upper left-hand side of photo is the blower that goes into the secondary chamber. The inflowing air is preheated before coming through the nozzles.
Another view of the above arrangement. Note the silver colored air-cylinder controls on the valves, which slide a dam in and out of place to block and open flow in the various places where such regulation is called:
Back side of older unit shown above. Flow of vapors is from left to right.
Looking into secondary burner of new unit. Note angled nozzles for inflow of air in circular motion. Ignited vapors come in through center.
Looking into secondary burner of newer unit (not as close-up as photo prior).
New secondary burner unit, ready to go into use. View is looking into tire vapor intake and waste-oil pre-heat intake channels. Flat, circular object on left below burner unit is the lid for the primary burner. The blower fan on the bottom middle of the photo is not situated for operation but needs to be installed.
Bottom right is waste-oil ignition control valve for primary tire vaporizing cylinder. Center bottom of photo is blower unit for air flow into chamber. Horizontal chamber across top of photo is where the vapor flows from the primary into the secondary chamber (left).
Looking into older secondary burner. Note the ceramics are not in good shape because of higher-than expected temperatures. Note nozzles in center of photo.
Second half of old secondary burner, disassembled, setting alone on ground. Shape tapers from large to small for jet-like emission.
Top of newer secondary burner. Top hole is for intake of blown air, which is preheated before coming into the chamber through the nozzles.
Two more views of the newer secondary burner unit.
Both lids. Older one is setting flat. Newer is on right, leaning against legs of secondary burner (just out of picture above).
Same view as photo prior, except showing bottom portion of secondary burner exit.
Same objects, looking from another angle. Note on the primary burner lid leaning against the secondary burner legs that there are pressure release valves in the case of a back-flash.
Tire vaporizer cylinder of newer unit. Not yet attached to anything. Note vapor outlet going off to right of cylinder just above half-way up on the cylinder. Older secondary burner (second half) is sitting on ground to the right of the cylinder.
Closer view of above photo.
Even closer view. Note air holes in bottom of cylinder for inflowing air. Modification of design will have a removable holding cylinder drop down inside the primary chamber.
Primary tire vaporizer of older unit to right in photo. Secondary unit is attached, going to the left and behind. Newer secondary unit is setting separate in the left in the photo.
Tire vaporizing chamber of older system. The secondary burner is going off to the right and behind. About 100 feet behind, and to the left is the newer vaporizing chamber.
Another view from behind. Tire vaporizing chamber is on left. Shadows make the objects difficult to distinguish. The secondary burner of the newer unit is on the right, and behind the secondary burner of the older unit by about three feet. See also |
