“…CO 2 enrichment was performed to maintain a CO 2 concentration above 1375 mg/Nm 3 ; this only happened during periods when the greenhouse ventilation windows could be kept closed. The CO 2 enrichment procedure has been recommended in previous works [21,37]. These experiments were performed in two multi-span "Parral-type" greenhouses.…”

This work presents an alternative for adding value to greenhouse crop residues, used for (1) heating and (2) as a CO2 source. Both options are focused on greenhouse agricultural production, but could be applied to other applications. The influence of factors, such as the air/fuel rate and turbulence inside the combustion chamber, is studied. Our results show that for pine pellets, olive pits, tomato-crop residues, and a blend of the latter mixed with almond prunings (75–25%), the thermal losses ranged from 19.5–53.1, 20.5–58.9, 39.9–95%, and 29.4–75.5%, respectively, while the NOX emissions were 30–247, 411–1792, and 361–2333 mg/Nm3, respectively. The above-mentioned blend was identified as the best set-up. The thermal losses were 39.2%, and the CO, NOX, and SO2 concentrations were 11,690, 906, and 1134 mg/Nm3, respectively (the gas concentration values were recalculated for 0% O2). Currently, no other work exists in the literature include a similar analysis performed using a boiler with a comparable thermal output (160.46 kW). The optimal configurations comply with the relevant local legislation. This optimization is important for future emission control strategies relating to using crop residues as a CO2 source. The work also highlights the importance of ensuring a proper boiler set-up for each case considered.

“…The flue gas produced by syngas-air combustion travels inside the spiral chimney and transfers its heat to the water surrounding the chimney. The calorific value of the syngas is calculated based on the calculation of the rejected heat from the flue gas and the change in temperature of the water [13].…”

With the need for developing a more sustainable world, there is a desire to shift from fossil fuels to biofuels, produced using the concept of biorefineries. Within the last few decades, thermochemical conversion technologies have gained a great deal of attention for producing advanced biofuels. In this context, this chapter elaborates different aspects of biomass gasification technology, as a representative of thermochemical pathways, and suggested potential solutions to enhance the efficacy of the process. To fulfill this goal, different types of biomass feedstock are employed to examine the potential of each in bioenergy production through gasification process. The chapter is consisting of a series of dependent studies to investigate the path for advancements in the gasification process. The first study investigates the parametric effect of experimental conditions during gasification of individual biomass feedstocks to select the best biomass feedstock for next study. It is also demonstrated that how the variation in the syngas composition interacts with H 2 /CO ratio. The other study investigates the potential of composite feedstocks based on the results from the first study. The last study investigates the potential failure scenarios and the likelihood of their occurrence are explored.

“…The major part of described research in literature deals with the effect of catalysts at single-room heaters [9,[13][14][15][16][17][18][19][20]. Only some results have been presented from boilers with catalysts [21][22][23]. The batch-combustion, carried out in furnaces using wood logs as fuel, results in strongly fluctuating conditions.…”

“…When the catalyst position is inside the furnace, the temperature can rise up to 750-850 °C [9,17,22], dependent on the distance to the flame. Since the highest pollutant emissions are generated during start and burnout phases, when the temperatures are low, catalyst heating systems are sometimes applied to gain higher pollutant reduction [14,[21][22][23]. Literature data show that catalytic conversion rates vary in a wide range and can be hardly compared because of the multitude of differences in the process conditions and mostly not precisely described catalyst probes.…”

“…The often applied noble metal catalysts based on platinum and palladium provide a high activity for CO oxidation. With a good dimensioned and active catalyst reduction rates over 90 % can be realized [19,20,21]. Nevertheless, very high pollutant concentrations [13,18], catalyst bypassing due to leakages [15] or insufficient process temperatures [23] can restrict the performance of the applied catalysts.…”

Characterization and integration of oxidation catalysts at small-scale biomass combustion furnaces

Abstract. Small-scale biomass combustion is a major part in heat supply from renewable resources. Drawbacks to the environmental background are the pollutant emissions, which are formed as a result of maloperation, suboptimal furnace construction or the biomass fuel composition. The named primary factors can be influenced by several measures, but the achievable emission results are limited. To provide real clean combustion technology with nearly zero pollutant emissions, secondary emission reduction measures are necessary. One of these measures is the application of catalytic flue gas cleaning as integrated or downstream solution. Catalysis is already a state of the art element in many processes and following this, some studies reveal already its potential to reduce CO, VOC as well as particle emissions in small-scale biomass combustion systems. However, a wide application of catalysts in wood combustion units didn't take place so far, because the challenging process conditions demand a proper integration and highly stable and active catalytic materials. For the achievement of well-functioning combustion systems with catalyst solutions a procedure for application-oriented characterization is presented. Initial investigations with commercially available catalysts have shown that the gas hourly space velocity and the oxygen content have the most significant influence on the conversion rate of carbon monoxide and nitrogen oxide. Two samples with different active phases have been compared, one with solely metal oxides and one with metal oxides and noble metals. The one with noble metals showed as expected a higher activity, but also a higher stability.
