Problems solved by technology

Compressing the syngas requires energy, reducing the efficiency of the IGCC system
Syngas cooling is usually achieved by water washing, and similarly, said cooling requires energy with a corresponding drop in efficiency

Embodiment Construction

[0011] Although specific features of the various exemplary embodiments of the invention may be shown in some drawings and not in others, this is for convenience of illustration only. In accordance with the principles of the invention, any feature of a drawing may be referenced and / or claimed in combination with any feature of any other drawing.

[0012] figure 1 is a schematic diagram of an exemplary system 100 for generating electricity using syngas produced from biomass. System 100 includes a biomass dryer 102 that receives biomass from a source 104 . Biomass conversion reactor 106 receives dried biomass 108 from biomass dryer 102 . Biomass conversion reactor 106 may be any suitable device that can be used to convert biomass to syngas to enable the systems described herein to function as described. For example, biomass conversion reactor 106 may be a biomass gasifier or a steam biomass converter. Biomass conversion reactor 106 vents syngas 110 . Syngas 110 mainly includ...

Abstract

Methods and systems for generating power using syngas created using biomass gasification are provided. Exemplary power generation systems include a biomass dryer for receiving biomass, a biomass conversion reactor (either a biomass gasifier or a steam-biomass reformer) for receiving the dried biomass and generating syngas therefrom, and an external combustor for combusting the syngas and heating a working fluid to drive a turbine connected to an electrical generator. The external combustor includes a heat exchanger element for transferring heat from combustion of the syngas into the working fluid, while maintaining the working fluid isolated from the syngas and from syngas combustion products.

Description

technical field [0001] The present invention relates generally to an integrated gasification combined cycle (IGCC) power generation system, and more particularly to a turbine power generation system incorporating fuel produced from biomass material. Background technique [0002] At least some known IGCC systems include a gasification system integrated with at least one power generating turbine system. Many of these IGCC systems include a gasifier that produces a combustible gas or a combustible gas precursor that is further processed into a combustible gas (referred to as "syngas"). Such IGCC systems typically further include a gas turbine in which the syngas is combusted and / or which is driven by combustion by-products produced by combusting the syngas. [0003] An ideal syngas or syngas precursor feedstock source is a biomass material, as the use of biomass material can reduce the dependence on other syngas feedstock sources, such as fossil fuel based feedstocks such as c...
