Gas turbine power plant

An improved gas turbine power plant using a state of the art gas turbine in which heat energy is supplied by burning wood comprising:

• (A) a state of the art gas turbine apparatus having at least one gas-driven turbine section and a compressor section for supplying a first pressurized gaseous stream;
• (B) a combustor for burning wood volatilized gases to form combusted gases to provide heat energy for driving the turbine;
• (C) at least a first heat exchanger means for transferring a portion of the heat energy provided by said combusted gases to said pressurized gaseous stream;
• (D) at least a first heat recovery steam generator which converts water to a first steam flow wherein said first steam flow is mixed with the pressurized gaseous stream from said compressor section to form a gaseous mixture and wherein said gaseous mixture is fed to drive said turbine section;
• and
• (E) at least one wood volatilizer means having a first conduit inlet for receiving wood particles, a second conduit inlet for receiving hot air heat from said first heat exchanger means, a third conduit outlet for passing wood volatilized gases from said volatilizer means to said combustor, and a fourth conduit outlet for removing ash.

A process for operating a gas turbine power plant using a gas turbine in which the heat energy is supplied by burning wood, comprising:

• (a) passing a gas through the compressor section of a gas turbine apparatus having at least one gas-driven turbine section and a compressor section for supplying a first pressurized gas stream;
• (b) passing spent gases from said turbine section through a first conduit inlet in a combustor;
• (c) passing wood volatilized gases to a second conduit inlet in said combustor, burning said volatilized gases to form combusted gases and transmitting out of a third conduit outlet from said combustor, said combusted gases;
• (d) discharging said combusted gases from said combustor to a first heat exchanger means through a first conduit inlet and passing the combusted gases from said heat exchanger through a second conduit outlet;
• (e) passing said pressurized gaseous stream from said compressor section along with a steam flow that is mixed with the gaseous stream to form a gaseous mixture through a third conduit inlet;
• (f) heating said gaseous mixture in said first heat exchanger means and passing said gaseous mixture out of a fourth conduit outlet in said heat exchanger means to drive said turbine section;
• (g) receiving said combusted gases from the second conduit outlet in said heat exchanger through a first conduit inlet in said steam generator means, receiving water through a second conduit inlet and converting said water to said steam flow;
• and passing said steam flow through a third conduit outlet from said steam generator means;
• (h) mixing said steam flow with said first pressurized gases prior to the gaseous mixture passing through the first conduit inlet in said heat exchanger;
• (i) discharging said combusted gases from a fourth conduit outlet in said steam generator means;
• (j) passing wood particles to a first conduit inlet in at least one volatilizer means which convert said wood particles to wood volatiles and ash;
• and
• (k) removing the ash from the second conduit outlet in said volatilizer and passing the wood volatiles through a third conduit outlet to said second conduit inlet means in said combustor so as to provide the fuel that is burned in said combustor.
