The analysis of variable factors affecting the gas-producer plant functioning has been carried out. The study has shown that the most significant factor affecting the gasification process in the reaction zone of the gasifier is the supply mode of O2 oxidizing agent, which is the atmospheric air. Having taken into account the results of the exploratory studies, the authors have patented and proposed parametric control elements of the oxidizing agent supply in the plane and volume of the gasifier reaction zone. The article deals with the basic control modes of the blast lances of the gasifier, such as static, dynamic synchronous and dynamic asynchronous ones. The method of calculation of the oxidizer flow rate under different control modes of the blast lances, under condition of maintaining the rate of airflow out of the lance in the optimal range of speeds is given.

Cleaning Technology

Gas from the gasification of pellets made from renewable sources of energy or from lower-quality fuels often contains a number of pollutants. This may cause technical difficulties during the gas use in internal combustion gas engines used for energy and heat cogeneration. Therefore, an adequate system of gas cleaning must be selected. In line with such requirements, this paper focuses on the characterization and comparison of gases produced from different types of biomass during gasification. The biomass tested was wood, straw, and hay pellets. The paper gives a detailed description and evaluation of the measurements from a fix-bed gasifier for the properties of the produced gases, raw fuels, tar composition, and its particle content before and after the cleaning process. The results of elemental composition, net calorific value, moisture, and ash content show that the cleaned gases are suitable for internal combustion engine-based cogeneration systems, but unsuitable for gas turbines, where a different cleaning technology would be needed.

Representative Model

This research is based on obtaining a mathematical model to determine the efficiency of generating a generator coupled to a biomass gasification process. To do this, it is initially simulated internal combustion engine at the Aspen hysys® licensed software, in order to obtain the shaft work and a representative model of the generation efficiency of the motor; according to the characteristics of the power cycle and product gas from the gasification of agricultural biomass prevailing in the Department of Córdoba – Colombia: Cotton waste (Gossypium hirsutum), Rice husk (Oryza sativa), Sesame stalk (Sesamum indicum), Corn cob (Zea mays) and Coconut fiber (Cocos nucifera). Subsequently, the generator efficiency is evaluated by the electric power generation simulation phase in the Simulink Toolbox of the MATLAB® software. The deterministic mathematical models resulting from the simulations above are adjusted by statistical techniques to experimental data and a regression model that assesses the overall system efficiency is obtained. Such efficiencies range from 16 to 20%. Therefore it is concluded that the use of representative crops biomass product’s calorific values in the Department of Córdoba -Colombia, are profitable for electric power generation. On the other hand, it is important to note that experimental data’s reliable and monitored way acquisition was performed through the SCADA developing; it allowed real time process variables’ intervention presentation.

Feather Digestion

The aim of this research was the elaboration of the technological parameters of biological digestion and biogas production from poultry feather produced in large quantities by slaughterhouses. Feather protein was digested by Bacillus licheniformis, keratin desintegrator bacteria. Investigations focused on the optimalization of parameters influencing poultry feather biodegradation. The optimal range of pH, temperature, feather size and bacillus:feather ratio were determined in the experiments as well as the analysis of relationship between the examined parameters. In order to be able to track the dinamics of the biodegradation, we determined the extintion level of the liquid phase of the biodegraded material in the different experimental treatments. The results showed that the rate of hydrolisis was significantly higher in the treatments with bacteria than in the treatments without it. The most extensive digestion were observed in case of 1:3 feather:water ratio. The highest intensity of feather digestion were detected in the treatment with 1% microbe ratio.

Syngas Cleaning

This study aims to examine the process of cleaning for synthesis gas (syngas) resulted from candlenut shell gasification by using a cyclone. Research was started by design or manufacture a cyclone as a tool that can condense the tar carried in the syngas produced from the gasification process. This tool was tested with by trial and error such that got a tool that can function optimally to condense tar. The syngas cleaning experiment using the cyclone was conducted by four treatments, namely S1 (1 cyclone), S2 (2 cyclones), S3 (3 cyclones), and S4 (4 cyclones).  All treatments were repeated 4 (four) times, so there were 16 experimental units. The parameter measured is the amount of tar that was condensed on the cyclone. Result showed that the syngas cleaning process using a cyclone worked well, and the best treatment was S3 (3 cyclones) with an average amount of condensed tar of 141.7 ml/kg of shell. The use of cyclones can condense tar and other particulates carried in the syngas. The cleaned syngas can be applied as fuel in an internal  combustion engine as a substitute for diesel and gasoline fuels.       Keywords: gasification, syngas, cleaning, cyclone

The article is devoted to the development of a generalized methodology for calculating the joint characteristics of an internal combustion engine and transmission of a mobile unit. The technique allows considering transmissions of various physical nature: electric, hydraulic. The peculiarity of the technique is that the power transmission of any physical nature can be represented by a generalized model, a four-terminal device, the input of which is affected by the values of Мin, nin, and the output is Mout, nout. As a result of the calculations, graphical dependencies of the joint characteristics of the internal combustion engine and transmission, the efficiency of the generator and the electric motor, and the mechanical and electromechanical characteristics of the electric motor are obtained.

The aim of the presented article is to analyse the influence of synthesis gas composition on the power, economic, and internal parameters of an atmospheric two-cylinder spark-ignition internal combustion engine (displacement of 686 cm3) designed for a micro-cogeneration unit. Synthesis gases produced mainly from waste contain combustible components as their basic material (methane, hydrogen, and carbon monoxide), as well as inert gases (carbon dioxide and nitrogen). A total of twelve synthesis gases were analysed that fall into the category of medium-energy gases with lower heating value in the range from 8 to 12 MJ/kg. All of the resulting parameters from the operation of the combustion engine powered by synthesis gases were compared with the reference fuel methane. The results show a decrease in the performance parameters for all operating loads and an increase in hourly fuel consumption. Specifically, for the operating speed of the micro-cogeneration unit (1500 L/min), the decrease in power parameters was in the range of 7.1–23.5%; however, the increase in hourly fuel consumption was higher by 270% to 420%. The decrease in effective efficiency ranged from 0.4 to 4.6%, which in percentage terms represented a decrease from 1.3% to 14.5%. The process of fuel combustion was most strongly influenced by the proportion of hydrogen and inert gases in the mixture. It can be concluded that setting up the synthesis gas production in the waste gasification process in order to achieve optimum performance and economic parameters of the combustion engine for a micro cogeneration unit has an influential role and is of crucial importance.
