Drawings are available for the belt driven spinning cup
burner. The bearings of the spinning cup are cooled by fluid flowing through
a cooling jacket. The spinning cup spindle must operate on top of the combustion
chamber, a thermally hostile environment, hence the necessity for the cooling
jacket. The spinning cup spindle is driven by a timing belt. This arrangement
allows the electric motor to be placed in a cooler location. Originally
the cup was driven directly by the motor, which was included in the cooling
jacket. The change to the belt driven arrangement was made after a motor
over heating failure. The
spinning cup operates at 8000 rpm, so a larger selection of motors can be used with a step up ratio on the pulleys. Provision is available to renew the supply of oil to the spindle bearings. The combustion chamber and spinning cup has been working trouble free for 7 years.
There is a video tape available that shows step by step the construction or the sheet metal for the combustion chamber. The tape shows the proper sequence for making the spotwelds. If this sequence is not followed you will not be able to complete the assembly by spotwelding as the electrodes will not be able to reach the joints. The video tape is a big aid in building the combustion chamber.
Steam Generator Drawing sets are available. Combustion Chamber
