Pressurised combustion of biomass-derived, low calorific value fuel gas

Objectives

A potentially attractive option for using biomass for power production is the application of advanced biomass-fuelled integrated gasification combined cycle (IGCC) systems. The relatively few cases in which IGCC systems have been realised have shown that it is very difficult to predict reliably the behaviour of the system as a whole and the gas turbine in particular. For the design of advanced power production systems based on the utilisation of biomass, reliable information is needed. This information should be available in a form that can be used in industrial design practice. The objective of the project is to develop a stationary and dynamic mathematical model, describing the processes in a combustor, which uses biomass-derived low calorific value fuel gas, and to gather reliable experimental data to validate and refine the model. The results of the experiments and the model will be used in the development of a plant layout that incorporates a gas turbine suitable for operation on low calorific value fuel gas.

Technical Approach

European Gas Turbines (EGT) will design, manufacture and supply a gas turbine combustor for low calorific value fuel gas to be tested downstream of the Delft University of Technology (DUT) biomass-fuelled 1.5 MW pressurised fluidised bed gasifier. EGT will also develop a dynamic model of the combustor. Fluent Europe will develop a detailed mathematical model for the stationary behaviour of the combustor. DUT will perform the experimental investigations of the combustor behaviour and will also specify the parameters for stationary mathematical models and will validate the models. DUT will design a plant layout based on information provided by EGT and will study the stationary and dynamic behaviour of the IGCC system.

Expected Results

The outputs of this project are:

a pressurised, high temperature combustor for biomass-derived low calorific value fuel gas
basic experimental information on the stationary and dynamic characteristics of the combustor
results of numerical simulations using a validated mathematical model describing the stationary behaviour of a pressurised, high temperature combustor
results of numerical simulations using a validated dynamic model of the combustor
a plant layout for an advanced biomass-fuelled IGCC system
results of numerical simulations of the stationary and dynamic behaviour of the proposed IGCC system.

Within three years, the combined effort of the partners in this project will lead to information which can be used for the design of full scale, biomass-fuelled industrial power production systems.
