“…Drawback that can provoke mismatch between power supply and demand which in turns can result in management and control problems, devices fault or, even worse, from local to global blackout. Obviously, these issues can be easily solved developing and installing large-scale energy storage plants (see, e.g., References [8][9][10][11][12][13][14][15][16]) and managing properly fossil fuels power units in order to avoid components life-time reduction (see, e.g., References [17][18][19][20][21][22][23]). Independently to these facts, wind and solar can not guarantee a both stable and programmable production as well as a simultaneous generation of electricity and heat/cold: strengths of plants working with bioenergy as input.…”

Despite biogas renewability, it is mandatory to experimentally assess its combustion products in order to measure their pollutants content. To this purpose, the Authors selected six in-operation biogas plants fed by different substrates and perform an on-site experimental campaign for measuring both biogas and engines exhausts composition. Firstly, biogas measured compositions are compared among them and with data available in literature. Then, biogas engines’ exhaust compositions are compared among them, with data available in literature and with measurements obtained from an engine characterised by the same design power but fuelled with natural gas. Finally, the Health Impact Assessment analysis is used to estimate the damage on human health caused by both biogas and natural gas engines emissions. Results show that biogas causes a damage on human health three times higher than the natural gas one. But, this approach does not consider biogas renewability. So, to include this important aspect, also an analysis which considers Global Warming categories is carried out. Results highlight that natural gas is twice harmful than biogas.

“…In order to enable analysis of processes for NO x /SO 2 emission reduction, submodels of NO x formation/destruction reactions and Ca-based sorbent calcination/sintering/sulfation reactions were selected, coupled with the in-house developed combustion code and applied for investigation of de-NO x primary measures and de-SO 2 by Furnace Sorbent Injection (FSI) method [78][79][80][81][82][83][84][85][86]. In order to enable efficient data input and meet the real engineering needs, a new user-friendly software interface, was developed as well [80,83].…”

“…Comprehensive study of in-furnace SO 2 control was done over a wide range of operating conditions. Injecting 10 µm CaCO 3 particles into the case-study furnace through the burner tiers provided SO 2 reduction of over 45% at the furnace exit [82,[84][85][86].…”

The burning of all fossil fuels is accompanied by the production of large quantities of nitrogen oxides. Nitrogen oxide from coal combustion is formed from the molecular nitrogen in the air and the nitrogen contained in the fuel. In accordance with the mechanism of formation of nitric oxide from fuel, it is desirable to increase the concentration of coal dust in the flame. The thermal regime of combustion accelerates the release of volatiles, with flames spreading out and the coke residue contributes to the chemical reduction of NOx. In this work we consider the specific issues of the formation mechanism of NOx fuel and ways to reduce their atmospheric emissions. Presented are results from the calculation of the influence of the following on the level of nitric oxides during coal combustion: temperature, oxygen concentration and time of release of fuel nitrogen. It has been established that the influence of nitric oxide fuel on the total nitric oxide emissions is more noticeable at low temperatures of the combustion process.
