Abstract
Abstract A fluidized solids reactor which is capable of using either a gaseous fuel or a liquid fuel. The reactor employs a fuel system capable of supplying either a gas or a liquid to novel nozzles. The nozzles disperse the fuel throughout the fluidized bed of pulverulent material. Each nozzle includes a pair of concentric tubular members each opening into the fluidized bed. When gas is used as fuel, it is supplied to the outer tube. When oil is used as a fuel, it is supplied to the inner tube of the nozzle and air under pressure is also supplied to the inner tube. In addition, when liquid fuel is used, air under pressure is supplied to the outer tube for cooling the inner pipe.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
In a fluidized solids reactor including a vessel, a gaspermeable grid mounted in and dividing said vessel into a lower plenum chamber and an upper material chamber and adapted to support a bed of pulverulent material in the material chamber, means for supplying gaseous fluid to the plenum chamber for passage through the gas-permeable grid to fluidize the bed of pulverulent material, an outlet for discharging spent fluidizing gas from the material chamber, and means for supplying fuel to the material chamber for combustion in the fluidized bed of pulverulent material comprising: nozzle means flow connected with the means for supplying fuel and dispersing the fuel into the fluidized bed of material, said nozzle means including a pair of concentric, hollow tubular members; means flow connected to one of said tubular members for selectively supplying gaseous fuel to said nozzle means; means flow connected to the other of said tubular members for selectively supplying liquid fuel to said nozzle means; and means flow connected to said tubular member which has said means for selectively supplying liquid fuel flow connected thereto for supplying air to said nozzle means when liquid is supplied to said nozzle means.
Claim 2
Dependent Claim

In a fluidized solids reactor including a vessel, a gaspermeable grid mounted in and dividing said vessel into a lower plenum chamber and an upper material chamber and adapted to support a bed of pulverulent material in the material chamber, means for supplying gaseous fluid to the plenum chamber for passage through the gas-permeable grid to fluidize the bed of pulverulent material, an outlet for discharging spent fluidizing gas from the material chamber, and means for supplying fuel to the material chamber for combustion in the fluidized bed of pulverulent material comprising: nozzle means flow connected with the means for supplying fuel and dispersing the fuel into the fluidized bed of material, said nozzle means including a pair of concentric, hollow tubular members; means flow connected to one of said tubular members for selectively supplying gaseous fuel to said nozzle means; means flow connected to the other of said tubular members for selectively supplying liquid fuel to said nozzle means; and means flow connected to said tubular member which has said means for selectively supplying liquid fuel flow connected thereto for supplying air to said nozzle means when liquid is supplied to said nozzle means.
Claim 3
Dependent Claim
37 words
In a fluidized solids reactor according to claim 1, said means for supplying fuel further comprising means for supplying air to said one of said tubular members when said other tubular member is supplied with liquid fuel.
