“…A number of studies have looked into the calorific content of corn stover. An average value from these studies was taken and it is assumed that the energy that is given off when burning dry maize stover is 17.4 MJ·kg −1 [ 57 , 58 , 59 , 60 , 61 ]. Therefore the amount of maize stover that is required is 18.3 kg per hour which is only around 13.9% of the biomass that is used in each extraction.…”

To date limited work has focused on assessing the economic viability of scCO2 extraction to obtain waxes as part of a biorefinery. This work estimates the economic costs for wax extraction from maize stover. The cost of manufacture (COM) for maize stover wax extraction was found to be €88.89 per kg of wax, with the fixed capital investment (FCI) and utility costs (CUT) contributing significantly to the COM. However, this value is based solely on scCO2 extraction of waxes and does not take into account the downstream processing of the biomass following extraction. The cost of extracting wax from maize stover can be reduced by utilizing pelletized leaves and combusting the residual biomass to generate electricity. This would lead to an overall cost of €10.87 per kg of wax (based on 27% combustion efficiency for electricity generation) and €4.56 per kg of wax (based on 43% combustion efficiency for electricity generation). A sensitivity analysis study showed that utility costs (cost of electricity) had the greatest effect on the COM.

“…An emission extreme at a burning time of 35-40 min can indicate unstable aerodynamic conditions in the furnace, for example, collapse of a uniform fuel layer in the furnace. Morissette et al [13] measured average emissions of CO, NO x and SO 2 for burning corn stover 2725, 9.8 and 2.1 mg/m 3 and average emissions of CO, NO x and SO 2 for burning round bales 2210, 40.4 and 3.7 mg/m 3 . It is interesting that changes in nitrogen oxides were correlated with changes in oxygen content (Figure 4) [13].…”

As emerged from these results, an acceptable solution could be more frequent feeding of a smaller fuel quantity at shorter intervals.…”

This article provides possibilities for minimising the emissions from eight types of biomass combustion boilers given by virtue of continuous emission measurement. The measurements were carried out on various types of one-or two-stage combustion devices. In all investigated modes of combustor operation, the concentration of nitrogen oxides in the whole cycle of fuel combustion was without marked deviations and far lower than the emission limit of 650 mg/mn 3. Concentrations of carbon monoxide (CO) and total organic carbon (TOC) are extremely variable at some operating schedules of combustion boilers. The variability of these concentrations indicates that there are unstable aerodynamic conditions in the combustion device. The causes of this aerodynamic instability have been studied. The mode with stable aerodynamic conditions, for which emission concentrations of CO and TOC are relatively stable, has been determined.

“…This makes cigar firing organization much more suitable, since it preserves the continuity of the combustion process, in contrast there are no sudden changes of temperature and harmful products emissions in cigar-type boilers (Mladenović et al, 2009). Also, combustion biomasses can cause different problems such as: slagging; premature corrosion of the furnace metallic components; the high level of alkalis in crop residues may lead to aerosol formation, resulting in ash melting temperature drop, fouling and emission issues (Morissette et al, 2013).…”

Unfavorable conditions for flax growing, harvesting and dew-retting are the reason for the low-quality flax biomass production. This biomass cannot be processed for fiber or other purposes. Therefore, flax straws are burned in the fields or are used as fertilizer by plowing into the soil, which are not good solutions for the environment and subsequent cultivation operations. The limit values of quality properties of fibre flax stem, flax straw and retted straw for their processing are summarized, which can be used to determine the suitability of flax straw biomass for processing or burning. Low-quality flax biomass is inexpensive, ecofriendly and renewable, it can be used as solid fuel for heating greenhouses or buildings located near the field where the flax is grown. Various techniques of fibre flax and oilseed flax harvesting are presented in the article. The technique of low-quality flax harvesting is recommended, which include flax pulling out or flax cutting, flax threshing, flax straw windrow forming, flax straw natural drying on the field in natural way, flax bale forming, flax bale transporting, flax bale burning. This harvesting technology can be used for low-quality fibre flax and oilseed flax. Flax straw biomass can be baled into three bale types: small rectangular bales, big round bales, and big square bales The main requirements for fuel flax biomass bales are recommended. The boiler for burning flax straw bales must be chosen taking into account the shape and size of the bales. For the efficient operation of boilers, it is necessary to take into account the recommended values of bale bulk density and moisture content of flax biomass.
