During my CENER visit by the Transnational Access by BRISK 2 I have got acquainted in CENER3 activities in the field of thermochemical applications of the CENER biomass energy research area, such as biomass gasification, as well. Moreover, I have had an overview of the whole CENER infrastructure in the research areas of renewable energy. 

At the stage of the preparation of the biomass it has determined the optimal kind of the biomass (pine chips) considering specialities of the region infrastructure and the chemical and physical features (both ultimate and proximate analyses, density, calorific value) of biomass fuels. According to the carried out ultimate analysis of pine wood chips it is determined that the carbon percentage is 50,6% in weight dry basis, the hydrogen percentage is 6.2% in weight dry basis, the nitrogen percentage is less than 0.23% in weight dry basis and the oxygen percentage is 43.1 % in weight dry basis. 

The proximate analysis has been carried out based on that there were calculated the humidity content which was determined as 14,9% and the ash content was determined as 0.5%. Moreover, it was calculated the density of the biomass which was 218 kg/m3. The low heat value of the pine wood chips was calculated as 19.0 MJ/kg. 

At the stage of experimental preparation, the optimal modes and their count have been chosen and has been developed a software for preparation experimental data and saving obtained results in a chosen place. The chosen model has characterized the following parameters: the power values of the gasifier were 1.4 MWt with increase up to 1.6MWt due to oxygen effects, equivalence ratio (ER) values were changed in the range of 0.28-0.35, the steam-oxygen ratio (SOv) values were changed in the range of 2.0-2.5. 

At the last stage the experiments will be carried out to determine the influence of the oxygen addition on the produced syngas performances (Low heat values, MJ/Nm3).  

To achieve the maximal value (9-10 MJ/Nm3) of the performance (LHV) needs to provide the following gasifier operation conditionals: ER is in the range of 0.28-0.29 and SOv is in the range of 2.0-2.2. The achieved maximal value of LHV are observed up to 9.6 MJ/Nm3 that is in two time more than typical value (4.48 MJ/Nm3) of gasification being provided with air carrier gas. 

Moreover, by decreasing SOv from 2.5 to 2.2 it was observed decreasing of gasification temperature due to additional oxygen chemical reactivity.  

Moreover, it was detected up to 200 oC decrease of temperature in gasification chamber by increase oxygen concentration on the modes which are characterized by achieving the parameters of gasification: ER =0.35 or SOv = 2.0. 

It has got knowledges about the gasifier control system Schneider Electric CPU67160, including with overview process, auxiliary systems, feeding biomass systems, syngas utilisation, start up and process preparation systems and gas analyser (Agilent Technologies 3000 Micro GC) as well.
