Abstract—Parametric studies performed using Taguchi methods in order to optimize an experimental process and the results of the development of a laboratory vertical fixed-bed gasifier are reported. It was demonstrated that gasification is a reliable process on a laboratory scale and its results can be used at pilot plants. It was found that the frequency of sample injection at constant weight, the particle size of biomass, and the amount of secondary air have a greater effect on the formation of CO and H2 than that of the moisture content of the biomass and the process temperature.

INTRODUCTION Reducing greenhouse gas emissions is a problem of considerable current interest closely related to the development of energy production from renewable energy sources. In recent years, power engineering in most countries has been associated with the development of renewable energy sources. According to experts, renewable energy sources (biomass, hydropower, wind, geothermal energy, and biofuel) provided 18% of the total energy consumption in the world in 2015 [1]. In 2014, the fraction of energy from renewable sources was estimated at 16% of gross final energy consumption in 27 European Union Member States. For comparison, these values were 11.7 and 10.5% in 2009 and 2008, respectively [2]. It is expected that the European Union will reach 20% of total energy consumption from renewable sources by 2020 [3]. The fraction of renewable energy sources will increase significantly to reach 55% of the total final energy consumption by 2050. The fraction of renewable energy sources in electricity consumption in the high energy efficiency scenario will reach 64% [4].
Biomass is a renewable energy source, which is able to provide an increasing energy demand for the sustainable development of society. Biomass is defined as “green carbon,” which means organic carbon present in plants, cultures, animal wastes, and wastes related to human activities [5]. Currently, 12% of primary energy needed for our planet and 4% for the European Union are produced from biomass. According to assumptions, it can provide from 15 to 35% of the global energy demand by 2030–2050 [3]. There are the fol
