Fluidized bed with uniform heat distribution and multiple port nozzle |
摘要 |
A fluidized bed apparatus which produces a pyrolitic carbon coating with improved wear and porosity characteristics of the coating by producing a more uniform flat temperature profile throughout a reaction chamber in the area where coating is taking place. The apparatus has heating coils surrounding a lower end of the reaction chamber placed immediately adjacent one another at tight spacing. This contrasts to previous apparatus wherein heating coils were spaced between 2 cm and 5 cm apart. The apparatus also has a multi-jet nozzle to control a flow of gases through the reaction chamber. The jets in the nozzle comprise passages which are oriented such that the length of the passages lie on a series of cones having common axes.
