Abstract
The biomass combustion process is inevitably accompanied by the emission of pollutant gasses. This paper gives a comprehensive analysis of the external variables and combustion products of the biomass plant. The analyzed data were collected from 18 MWt boiler in combined heat and power plant Sremska Mitrovica over a period of four months. The correlations between the recorded data were determined using a unique methodology, which is based on association rule mining. The results of the study can be further used for the reduction of the harmful combustion products, as well as for the optimization of the operation process.

Climate changes are caused by nature and human activity, which are mostly related to energy production and industry [1]
It is well known that different factors such as moisture level, amount of oxygen and thermal energy released during biomass combustion can reduce or increase emissions of harmful gases
The paper presents a unique methodology for investigating the interdependence of the biomass boiler operation parameters, the external temperature and the products of the biomass process
Summary
Climate changes are caused by nature and human activity, which are mostly related to energy production and industry [1]. The combustion of fossil fuels has a harmful effect on the environment, primarily due to the emission of CO2 and air pollution, which can lead to significant climate changes in the future. The combustion process in conventional or CHP biomass plants uses biomass and air as the main inputs for the production of energy. In addition to the obtained energy, the process of biomass combustion is accompanied by the emission of pollutant gasses with carbon dioxide as the main representative [14]. It is well known that different factors such as moisture level, amount of oxygen and thermal energy released during biomass combustion can reduce or increase emissions of harmful gases. The authors of [29] showed that the low CO and NOx emission levels can be achieved by using improved boiler design and with continuous control of combustion parameters.
