Abstract
An apparatus and method for generating electrical energy utilizing a boiler and a gas turbine powered by a carbonizer. A carbonizer is provided which produces low-Btu gases which are passed to a gas turbine for driving the turbine, and a char which is passed to a boiler for powering the boiler. The turbine utilizes the low-Btu gases as its sole source of power and is operated independently of the boiler.
Claims12
Apparatus for generating energy, said apparatus comprising:
- means for carbonizing fuel in the presence of limestone to generate fuel gas and char including limestone containing sulfur generated during said carbonizing,
- a separator for receiving said fuel gas and char from said carbonizing means and for separating said char from said fuel gas,
- a gas turbine,
- means for passing said fuel gas to said gas turbine for driving same,
- means operatively connected to said gas turbine for generating electrical energy;
- a reactor,
- means for passing said char to said reactor for removing said sulfur from said limestone,
- a boiler,
- means for passing said char from said reactor to said boiler for powering said boiler, and,
- means operatively connected to said boiler for generating electrical energy.
