Highly efficient conversion of biomass to power and heat

Objective

The goal of the project is to develop an engineering and feasibility study aimed at evaluating the technical potential of:
- a biomass fed slagging cyclone gasifier capable of high ash retention - a filtering system based on a swirler and ceramic candles
- an indirectly fired gas turbine (IFGT) Both Danish (straw) and Mediterranean biomass (Arundo Donax, Cynara Cardunculus) will be considered.

The project is aimed at developing firing concepts to obtain an effective and reliable production of electricity and heat when biomass fuel is used. The biomass conversion via gasification has still severe technical difficulties, as the produced gas contains contaminants that can damage high efficiency turbines.
As an alternative to the very difficult hot gas clean up techiniques the present project proposes an Indirectly Fired Gas Turbine (IFGT), preceded by a filtering system based on a combination of a swirler and ceramic candles. The gasification unit is also innovative, as it works as a slagging cyclone gasifier, having large ash retention capability. Three possible applications will be studied:
- an advanced biomass fuelled "add on" topping cycle, based on cyclone gasifier, swirler and an indirectly fired gas turbine (IFGT)
- a system as the previous one(cyclone gasifier, swirler, IFGT), but built as a self sustained combined cycle ("power island")
- an advanced "add on" cyclone gasifier to produce low BTU gas to be burned replacing a conventional coal dust burner in a new or existing power plant boiler.

Both Danish (straw) and Mediterranean biomass will be considered.
