Power systems with a high share of variable renewable energy (VRE) represent challenge to system operators because the increased flexibility requirements and stability. This study analyses performance real power grid penetration VRE (mainly wind solar photovoltaic). A rule-based model is developed simulate behaviour. One European country was selected (Spain), limited international interconnections well-established decarbonisation scenarios by national organisations. Flexibility in future...
The management of sewage sludge still represents a challenge in the EU sustainability plan for biowaste. Although there are consolidated alternatives valorization (incineration, pyrolysis and gasification), technical issues related to heavy metals other pollutants not sufficiently understood considering whole waste-to-energy process. In addition, societal-economic environmental aspects usually included evaluation these conversion technologies. this study, we propose an integrated assessment...
Kinetic studies were conducted to elucidate the effects of diffusional limitations at particle scale during thermogravimetry analysis (TGA) char reactivity tests. The main objective was identify limiting phenomena that may occur biomass gasification experiments with CO2. used wood matter from pressed-oil stone (WPOS) (this is also called orujillo). rates WPOS measured four different sizes (0.06, 0.9, 1.2, and 2.1 mm), three CO2 partial pressures (0.20, 0.35, 0.50 bar), temperatures (800,...
Biomass gasification tests with air−steam mixtures were conducted in a bubbling fluidized-bed (FB) pilot plant. The effect of steam addition on the performance was studied for different air-to-biomass ratios and biomass throughputs. reactor operated near adiabatic conditions, aim reproducing behavior full-scale FB units. temperature mixture fixed at 400 °C all tests, value that can be achieved by energy recovery from off-gas without tar-condensing problems. stoichiometric ratio (ratio actual...
Experiments were carried out in a laboratory fluidized bed (FB) to characterize the devolatilization behavior of wood and various wastes at temperatures applicable FB gasification combustion, i.e. 750–900 °C. The fuels tested pellets made wood, meat bone meal, compost (from municipal solid wastes), as well dried granulates sewage sludge (DSS). Determination yields char, condensate light gas, composition gas time during pyrolysis single fuel batches was made. A simple model developed analyze...
