Abstract
Gasification is a technology that uses fuel to produce power and heat. This technology is also suitable for biomass conversion. Biomass is a renewable energy source that is being developed to diversify the energy mix, so that the Czech Republic can reduce its dependence on fossil fuels and on raw materials for energy imported from abroad. During gasification, biomass is converted into a gas that can then be burned in a gas burner, with all the advantages of gas combustion. Alternatively, it can be used in internal combustion engines. The main task during gasification is to achieve maximum purity and maximum calorific value of the gas. The main factors are the type of gasifier, the gasification medium, biomass quality and, last but not least, the gasification mode itself. This paper describes experiments that investigate the effect of temperature and pressure on gas composition and low calorific value. The experiments were performed in an atmospheric gasifier in the laboratories of the Energy Institute atthe Faculty of Mechanical Engineering, Brno University of Technology.
Highlights
Biomass is one of the most significant renewable energy sources worldwide
Renewable energy sources have covered almost 4 % of power production in the Czech Republic, and biomass is a major contributor to these sources
There are various ways in which biomass can be used for heat and power production, ranging from oil esterification, biogas production and biogas utilization to thermal processes such as pyrolysis, combustion and gasification
Summary
Biomass is one of the most significant renewable energy sources worldwide. Biomass technology has many advantages, e.g. there is a comparatively low negative impact on the environment, and it can be grown on surplus agricultural land that is not suitable for, or is not required for, food production purposes.In recent times, renewable energy sources have covered almost 4 % of power production in the Czech Republic, and biomass is a major contributor to these sources.There are various ways in which biomass can be used for heat and power production, ranging from oil esterification, biogas production and biogas utilization to thermal processes such as pyrolysis, combustion and gasification.

Direct combustion is the most widely used method for producing power from biomass. It is the oldest method, with well-mastered technologies. Low-capacity processing lines are mostly suitable for heat production from biomass, and not for more desirable power production
