“…The reduction of SO 2 emission by 60% when using M. × rotundifolia L. and M. crispa L. compared to the materials above indicates that this biofuel exhibits low emissivity and is environmentally friendly. The tested biomass is characterized by high NO x emission rates, which is consistent with the emission levels for wheat straw pellets, sunflower pellets, corn stalk pellets, and wood pellets obtained by Krugly et al [51], which is undoubtedly a disadvantage of these biofuels, and excessive use of this type of biomass can contribute to the formation of acid rain.…”

The paper presents the results of research on the physicochemical properties of plant biomass consisting of four mint species, these being Mentha × piperita L. var. citrata Ehrh.-'Bergamot', Mentha × rotundifolia L., Mentha spicata L., and Mentha crispa L. The research conducted consisted of the technical analysis of biofuels-determining the heat of combustion and the calorific value of the material under study, and the content of ash, volatile compounds, and humidity. In addition, elemental analysis was carried out for the biomass under study by determining the content of carbon, hydrogen, nitrogen, and sulfur. The research demonstrated that Mentha × piperita L. var. citrata Ehrh.-'Bergamot' had the highest energy potential with a gross calorific value of 16.96 MJ·kg −1 , and a net calorific value of 15.60 MJ·kg −1 . Among the tested materials, Mentha × rotundifolia L. had the lowest content of ash at 7.23%, nitrogen at 0.23%, and sulfur at 0.03%, and at the same time had the highest content of volatile fraction at 70.36%. When compared to hard coal, the estimated emission factors indicated a CO reduction of 29-32%, CO 2 reduction of 28-31%, NO x reduction of 40-80%, SO 2 reduction of 92-98%, and dust reduction of 45-61%, depending on the type of biomass used.Energies 2020, 13, 55 2 of 13 of harmful gas and dust emissions (CO 2 , NO, SO 2 ) [10], and reduction of mineral extraction and thus curbing environmental degradation caused by uncontrolled decomposition of unused biomass [11,12].One of the basic goals of a low-emissions economy is to reduce the flow of biodegradable waste mass within certain time limits. Reaching this objective will not be possible without the implementation and development of installations for the thermal conversion of residues from agricultural and agriculture-related production, especially in systems for managing residues in the herbal product industry [13]. Installations for the conversion of residues from the sector of agricultural, horticultural, and herbal production should ensure the possibility of fulfilling the adopted obligations to reduce biodegradable waste, and secondly, they should provide significant amounts of electricity and heat, mainly treated as energy from renewable sources [14,15]. In addition, it is still important to search for new, alternative energy sources characterized by low emission levels, including, apart from greenhouse gases, low dust emission [16,17]. Due to the growth of the herbal production sector, one can observe high potential for energy generation in the residues from herb production and, more importantly, in residues that cannot be offered on the consumer market.Poland is considered as a country with great capabilities in both the production of high-quality herbal raw materials and herbal processing. This is due to the fact that over the last decade the number of farms growing herbs in Poland has increased from 18,000 to 30,000, and plantations of herbs now cover an area of over 30,000 ha, whereas in the countries of the entire European Union, th...

“…In the case of ash content, similarities were found between M. × piperita L. var. citrata Ehrh.-'Bergamot' and rapeseed pods, as well as M. crispa L. in relation to wheat straw [41,51,52]. The remaining species of mint differed significantly in relation to the analyzed types of biomass.…”

“…In contrast, the combustion of several biomass-derived fuels in a small-scale modern pellet boiler led to total PAH emissions of 0.5 to 1.9 mg·kg −1 fuel [43]. Coal combustion is known to have naturally high PAH emissions [40].…”

Vast amounts of leaf litter have to be disposed of by city administrations. This biomass has the potential for energy conversion, but contamination with pollutants can adversely affect this usage. We investigated leaf litter samples from the city of Kassel by analyzing their heavy metal and polycyclic aromatic hydrocarbon (PAH) concentrations. Leaf samples were indeed contaminated with heavy metals and PAHs and contamination was influenced by provenience and collection technique. A simple cleaning system of washing and subsequent mechanical dewatering significantly reduced heavy metal concentration. Regression models were developed for contamination with heavy metals which showed that contamination could be successfully estimated using the total ash content of the sample as a predictor, with an R 2 of up to 0.77. It can be concluded that leaf litter from cities is a possible feedstock for energetic conversion, provided a cleaning step is applied.

“…The CO emission for the CLHM, although twice as higher as the one for coal, has also met those requirements. PBZ combustion gave visibly higher CO values, at the level of around 1,400 mg/Nm 3 at 10% O 2 d.g., yet still much lower as reported by Krugly [10] for pellet sewage sludge combustion 13,698 ± 6,762 mg/Nm 3 . Regarding the operation more valuable information is shown in Fig.…”

“…Allouis et al [9] investigated the co-combustion of pelletized poultry manure waste with olive pomace in a 50 kW burner installed in a water-cooled fire-place. Whereas, Krugly et al [10] discussed burning of the sewage sludge pellets in a commercial 13 kW pellet boiler. Therefore, the main aim of this research is to investigate the feasibility of burning or co-burning of the biomass, less commonly processed in household heat production.…”

Technical and environmental performance of 10 kW understocker boiler during combustion of biomass and conventional fuels

Abstract. This paper treats about the impact fuels from biomass wastes and coal combustion on a small boiler operation and the emission of pollutants in this process. Tests were performed in laboratory conditions on a water boiler with retort furnace and the capacity of 10 kW. Fuels from sewage sludge and agriculture wastes (PBZ fuel) and a blend of coal with laying hens mature (CLHM) were taken into account. The results in emission changes of NOx, CO 2 , CO and SO 2 and operating parameters of the tested boiler during combustion were investigated. The obtained results were compared with corresponding results of flame coal (GFC). Combustion of the PBZ fuel turned out to be a stable process in the tested boiler but the thermal output has decreased in about 30% compared to coal combustion, while CO and NO x emission has increased. Similar effect was observed when 15% of the poultry litter was added to the coal. In this case thermal output has also decreased (in about 20%) and increase of CO and NOx emission was observed. As a conclusion, it can be stated that more effective control system with an adaptive air regulation and a modified heat exchanger could be useful in order to achieve the nominal power of the tested boiler.
