Influence of Solar Installation on the Change of Fuel Structure of the Heating Plant

Poland as a member of the European Community is obliged to change its fuel structure on the energy market. This is a consequence of the accepted international obligations and concern for the environment. Changing the fuel mix should be aimed at reducing the share of coal, while increasing the share of renewable energy sources. Coal combustion is a source of harmful pollutants, while increasing use of renewable energy sources contributes to the improvement of the environment. The paper presents the use of a solar collector system as a supporting element of the process of heat production in traditional coal heating plants. The efficiency of the work of heating plant in particular months of the year is discussed. The impact of the solar installation on the change in the fuel structure of the heating plant has been assessed.
