Abstract
A method and apparatus for providing a steam boiler/combuster and gasifier that uses a primary dirty fuel, such as waste materials, or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels for co-generation of electricity while reducing harmful emissions. The primary fuel is burned in the combuster to create steam in the steam boiler. The steam turns a steam turbine thereby powering a first generator. The dirty exhaust from the combuster is scrubbed by a gasifier. The secondary fuel and oxygen are added to the dirty exhaust in the gasifier creating gas and ash. The gas powers an engine that turns a second generator and releases a cleaner exhaust.
Claims28
An apparatus for converting dirty fuels to steam and useful gas, the apparatus comprising:
- a combuster burning dirty fuels producing heat and exhaust;
- a steam boiler receiving the heat from the combuster to produce steam;
- a gasifier wherein biomass material and the exhaust from the combuster result in useful gas;
- and
- an engine operatively linked to the gasifier to produce power from the useful gas.
A method for providing electricity from the burning of dirty fuels while reducing harmful emissions, the method comprising:
- providing a dirty fuel;
- burning the dirty fuel in a combuster creating heat and exhaust;
- transferring heat from the burning of the dirty fuel in the combuster to a steam boiler to create steam;
- routing the steam into a steam turbine;
- turning the steam turbine to power a generator to create electricity;
- routing the exhaust from the combuster into a gasifier;
- providing biomass material;
- adding biomass material to the gasifier;
- operating the gasifier with the exhaust and the biomass material creating gas and ash;
- routing the gas into an engine;
- and
- operating the engine to power a generator creating electricity.
An apparatus for co-generation of power that reduces the pollution of a burned primary fuel, the apparatus comprising:
- a combuster for burning a primary fuel creating heat and dirty exhaust;
- a steam boiler operatively connected to the combuster for generating steam;
- a steam turbine operatively linked to the steam boiler for turning the steam into power;
- a first generator operatively connected to the steam turbine for turning the power into electricity;
- a gasifier linked to the combuster, wherein the gasifier receives the dirty exhaust, a secondary fuel, and oxygen to produce useful gas and ash;
- an engine operatively linked to the gasifier, whereby the engine is powered by the burning of the useful gas;
- and
- a second generator operatively connected to the engine to create additional electricity.
