Abstract
Disclosed is an apparatus and process for generation of thermal energy, and cogeneration which includes a variable speed rotating heat transfer apparatus for the fluidization and combustion of carbonaceous fuel. The apparatus has an integrally formed water cooled jacket and water cooled auger and is maintained at an inclination with respect to ground level. The apparatus and process allow for a wide range turndown ratio and is adapted to cause a multidirectional movement of the fuel to be combusted.
Claims13
Apparatus for combustion of fuel comprising:
- a preignition assembly having means to receive the fuel;
- a jacketed combustion chamber attached to said preignition assembly;
- a hollow shaftless auger extending from said preignition assembly to and through the combustion chamber for feeding said fuel thereto, said combustion chamber and auger being adapted for rotation about an axis which is inclined with respect to a horizontal;
- inlet means for the introduction of combustion air into said combustion chamber and exhaust means for gaseous products of combustion to leave said chamber;
- variable speed drive means engaged for rotation of said combustion chamber about said inclined axis;
- and means for fluidizing said fuel in said combustion chamber.
A method for combustion of fuel comprising:
- introducing the fuel into a preignition assembly to initiate combustion;
- subsequently introducing the fuel into a combustion chamber surrounded by a heat transfer jacket;
- said chamber having a shaftless auger extending therethrough;
- and
- rotating said combustion chamber and auger about an axis inclined with respect to the horizontal to cause multi-directional mixing of the fuel.
A method of generating energy comprising:
- introducing fuel into a preignition assembly;
- passing the fuel into a jacketed combustion chamber having an auger extending therethrough;
- rotating said combustion chamber and auger about an axis inclined with respect to the horizontal to cause multidirectional movement of the fuel for thorough mixing and combustion;
- removing heat of combustion from said chamber by means of a first cooling fluid circulating through said jacket;
- heating a second fluid by transfer of thermal energy from the first fluid to said second fluid, introducing said second fluid into conversion means for converting thermal energy to mechanical and/or electrical energy.
