Abstract
In order to improve the energy, operational and ecological efficiency of District Heating Systems (DHS) powered by a Combined Heat and Power (CHP) plant or a Heating Plant, Thermal Energy Storages (TES) should be used. Improvement of energy efficiency is primarily associated with greater operational efficiency of energy generation, improvement of operational efficiency and fewer start-ups and number of operating hours of peak boilers. Improving ecological efficiency is associated with lower emissions of pollutants into the atmosphere. The presented paper examines the impact of the use and operation of a TES built in a CHP plant supplying a large DHS on the amount of particulates emission to the atmosphere. Detailed research was carried out for Siekierki-Warsaw and Białystok CHP plants in Poland. The analysis allowed to determine the factors affecting the reduction of pollutant emissions and the volume of the energy effect of using a TES in the CHP plant. In order to objectify the results of the comparative analysis of the impact of TES in CHP plant on the emission of particulates, the so-called Comparative Index (CI) was in-troduced, which takes into account the volume of electricity and heat production and climatic conditions in the analyzed time periods. The CI for the analyzed years, should have a similar value so that the results of the comparative analysis are fully representative. This condition is met for the selected base and comparative year for the CHP plant and DHS of Białystok, so the detailed results of analysis are presented for this facility. As a result of the application of TES in Białystok CHP plant, significant environmental effects related to the reduction of particulates emission have been achieved, for example, the total amount of annual Particulate Matters (PM) emission (PM10 and PM2.5) has been reduced by 27% and the maximum emission by 29%. On the other hand, the average decrease in particulates emission in the heating season varied in the range of 10 - 50%, while in the summer season the values of particulates emission were at a comparable level. A significant decrease in annual and one-hour average concentrations for PM10 and PM2.5 and particulates fallout for these two analyzed years was also found. The use of TES to reduce the occurrence and nuisance of the smog phenomenon, the main components of which are PM, is proposed, and selected models of forecasting concentrations of pollutants in the air, including particulates emission, are presented in order to implement this type of activities.
