“…In the recent study of Loeser and Redfern [8], a smallscale (50 kWe) downdraft gasifier and anaerobic digester unit feed to a microturbine as the generation unit, the plant modelling was carried out in Aspenplus TM . Rabou et al [22] have performed an experimental study on the technical performance of a micro gas turbine (30 kW e ) operating on biomass producer gas and on the economical prospects of that concept for the CHP, in this study has been proved the emissions of CO, unburned hydrocarbons, and NO are over 200 times, 15 times, and 3 times lower than those of a gas engine of similar size, operating on the same biomass producer gas.…”

“…The integration of biomass gasification into small CHP plants (o1 MW e ) has been the subject of many recent studies, like [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Many of these studies focus the integration of biomass gasification with high-temperature solid oxide fuel cells, for instance, Omosun et al [10] and Panopoulos et al [11].…”

SUMMARYThe olive oil industry generates several solid wastes. Among these residues are olive tree leaves, prunings, and dried olive pomace (orujillo) from the extraction process. These renewable energy sources can be used for heat and power production. The aim of this paper consists of modelling and simulation of a small-scale combined heat and power (CHP) plant (fuelled with olive industry wastes) incorporating a downdraft gasifier, gas cleaning and cooling subsystem, and a microturbine as the power generation unit. The gasifier was modelled with thermodynamic equilibrium calculations (fixed bed type, stratified and with an open top). This gasifier operates at atmospheric pressure with a reaction temperature about 8001C. Simulation results (biomass consumption, gasification efficiency, rated gas flow, calorific value, gas composition, etc.) are compared with a real gasification technology. The product gas obtained has a low heating value (4.8-5.0 MJ Nm À3) and the CHP system provides 30 kW e and 60 kW th . High system overall CHP efficiencies around 50% are achievable with such a system. The proposed system has been modelled using Cycle-Tempo software s .

Biomass gasification at temperatures below 1300°C yields producer gas with a range of heavy hydrocarbons. These compounds, collectively known as tar, cause fouling and emission problems in equipment using the producer gas. This paper gives an overview of the work performed at the Energy research Centre of The Netherlands (ECN) on tar measurement, tar prevention, tar cracking, and tar removal. Much of the work has been performed in cooperation with partner institutes and industry. Measurement techniques discussed are the tar guideline, solid-phase adsorption (SPA) method, and tar dew point analyzer. On the subject of tar prevention, the effects of operating conditions, fuel composition, and bed materials in fluidized-bed gasifiers are covered. Tar cracking results are presented for catalytic materials, hightemperature treatment, and the use of plasma. ECN research on tar removal involves among others the development of the water-based GASREIP system and the oil-based OLGA technique.

“…There is also a large body of research on NOx emissions from micro gas turbines. These include experimental and numerical simulations of the combustion and emissions of micro gas turbines fuelled by pure ammonia or methane-ammonia [11][12][13]; experimental studies of the combustion and emissions of micro gas turbines fuelled by biofuels [14][15][16]; numerical simulations of the effect of pressure and fuel-air unmixedness on NOx emissions from gas turbines [17]; experimental studies of a new combustion chamber structure to reduce NOx emissions [18]; numerical simulations and experimental studies of the emissions of micro gas turbines fuelled by syngas [19,20]; numerical simulations of the emissions of micro gas turbines fuelled by vegetable oil or vegetable oil mixtures [21,22], etc. Most of the above studies have predicted or measured NOx generation from micro gas turbines based on the specific combustion conditions in complex flow fields in combustion chambers.…”

Thermal calculations and NOx emission analysis of a micro gas turbine system without a recuperator

A thermal calculation based on a table of thermal properties of gas was carried out for a micro gas turbine system without a recuperator. The performance parameters of the micro gas turbine system were obtained. The results of the thermal calculations were verified using Aspen Plus, and it shows that the thermal calculations fit well with the Aspen simulation results. Based on this thermal calculation method, the variation of the performance parameters of the micro gas turbine system under different pressure and temperature ratios was analyzed. The results show that there is no optimum pressure ratio within the general design parameters of micro gas turbines, which leads to extreme values of thermal efficiency. The NOx generation in the combustion chamber of the micro gas turbine based on the Zeldovich mechanism was modeled and analyzed by coupling the one-dimensional thermal calculation model with the NOx emission model. The relationship between NOx generation rate, molar fuel factor, the characteristic pressure, and the characteristic temperature was obtained. The results of the analysis show that, in terms of controlling NOx emissions from a gas turbine, the use of an increased pressure ratio has a significant advantage over an increased temperature ratio to improve the thermal efficiency of the micro gas turbine.
