“…High potential for reducing fossil fuel consumption lies in district heating systems, from generation, transmission and distribution to consumers, rationalizing their heat consumption. The commitments made by Poland also concern an increase in the share of renewable fuels in the energy balance [17,28]. One of the technological solutions for the implementation of these fuels is the co-combustion of coal and biomass in power boilers [29,30].…”

“…Cofiring of solid fuels and biomass is understood as a set of processes consisting of burning coal with various types of properly selected solid biofuels or products derived from their processing. This process may take place in already existing boilers with high power output while ensuring high efficiency of chemical energy conversion contained in the fuel being burnt [12,13,17,[31][32][33][34][35][36]. Increasing the share of renewable energy in the fuel structure, inter alia through co-incineration, resulting primarily in the reduction of greenhouse gas and sulfur emissions, is also of great importance for increasing the security of energy supply and supporting technological development [14,[37][38][39][40][41].…”

“…The disadvantage, however, is the problem of preparing the right mix and then feeding it to the grate so that the fuel is mixed in the right proportions. Improper preparation of the mixture may lead to the formation of craters after biomass firing, and after a longer exploitation may lead to point burning of the grate elements [17].…”

“…The impact of gaseous pollutants generated in the combustion process on the environment and human health is the subject of many scientific studies and publications [5,13,[15][16][17][18]. Heating boilers operating in conditions of variable loads (other than normal) generate a higher unit emission of harmful pollutants.…”

Environmental protection, and in particular air protection against pollution, is an extremely important element of the global policy of many countries. The problem of air pollution is particularly important in Poland, where the heating market is one of the largest in Europe and is based in 74% on the use of fossil fuels, in particular hard coal. One of the technological solutions for the implementation of cleaner fuels is the co-combustion of coal and biomass. This process enables the reduction of harmful pollutants such as CO2, SO2, and can be implemented in existing boilers. Heating boilers achieve the highest design efficiency during optimal load at the level of 85–95% of nominal power. Under such conditions, heat production is most efficient. During operation, boilers are often started, extinguished or run below rated output, resulting in increased emissions. This publication presents the results of measurements of efficiency and concentrations of pollutants in the WR water boiler during operation below the technical minimum. Hard coal was cofired in the boiler with biomass of wood origin. It was noted that the amount of biomass had a significant impact on the boiler efficiency and pollutant emission. Based on the research, it was also noted that it was possible to make a qualitative prediction of these parameters. The obtained results are an introduction to a deeper analysis and further research on the correlation between the amount of biomass and boiler power and the efficiency and concentration of pollutants.

“…However, the number of the analyzed variants and/or pollutants are relatively small, which narrows down the scope of these analyses [30,[32][33][34]. Some studies focus on a single energy source or a single pollutant [35,36]. Research into residential heating systems often fails to account for the impact of ventilation on pollutant emissions.…”

The article presents the results of a study aiming to select the optimal source of heat for a newly designed single-family home. Commercial software was used to compare heating and ventilation systems involving a bituminous coal boiler, a condensing gas boiler, a biomass boiler, a heat pump with water and glycol as heat transfer media. The effectiveness of natural ventilation, mechanical ventilation with a ground-coupled heat exchanger, and solar heater panels for water heating were evaluated. The analysis was based on the annual demand for useful energy, final energy, and non-renewable primary energy in view of the pollution output of the evaluated heating systems. The analysis revealed that the heat pump with water and glycol was the optimal solution. However, the performance of the heat pump in real-life conditions was below its maximum theoretical efficiency. The biomass boiler contributed to the highest reduction in pollutant emissions (according to Intergovernmental Panel on Climate Change Change guidelines, carbon dioxide emissions have zero value), but it was characterized by the highest demand for final energy. Mechanical ventilation with heat recovery was required in all analyzed systems to achieve optimal results. The introduction of mechanical ventilation decreased the demand for final energy by 10% to around 40% relative to the corresponding heating systems with natural ventilation.
