Co-firing ammonia (NH3) in coal-fired power plants presents an attractive method to expedite the global decarbonization process. Nevertheless, the challenge lies in reconciling the need for higher temperatures within the furnace with the imperative of maintaining low nitrogen oxides (NOx) emissions, which limits the widespread use of NH3 as a fuel....
The global energy sector is a substantial contributor to greenhouse gas emissions, responsible for approximately 75% of such emissions worldwide. Indonesia, ranking twelfth in energy consumption and ninth in global carbon dioxide (CO2) emissions from fuel combustion, is faced with the challenge of addressing its significant carbon footprint. This c...

Memories are encoded in neural ensembles during learning and stabilized by post-learning reactivation. Integrating recent experiences into existing memories ensures that memories contain the most recently available information, but how the brain accomplishes this critical process remains unknown. Here we show that in mice, a strong aversive experie...
Tato bakalářská práce se zabývá charakterizací produktů ze spalování a spoluspalování biomasy, vyprodukovaných velkými provozy na území České republiky. Provedením zkoušek, dle platné legislativy, byly zjištěny fyzikální, mechanické a chemické vlastnosti jak samotných vzorků, tak namíchaných směsí s jejich zastoupením. Díky těmto údajům dokážeme pr...

Given the importance of climate change it is vital to find a transition away from fossil fuels. The transition will include electrification of several sectors, for example road transport, but considering the strong dependency on carbon-based fuels and associated infrastructures, it is reasonable to assume that biomass-based hydrocarbon will play a ...

Co-Firing biomass in the form of wood dust or sawdust with natural gas is a new concept, which was performed in a specialized burner from the Riga Technical University. In order to test the burner, primary experimental test runs were performed to get an overview of flue gas behaviour. The addition of sawdust increased CO values but O2 values remain...

To evaluate the combustion characteristics of raw or torrefied bamboo wastes and coal blends, the co-firing process determined by cone and pollutant emission was investigated by thermogravimetric analysis coupled with Fourier transform infrared spectroscopy. The results showed that torrefaction improved the fuel properties of bamboo wastes. Torrefi...

The long-term storage of episodic memory requires communication between prefrontal cortex and hippocampus. However, how consolidation alters dynamic interactions between these regions during subsequent recall remains unexplored. Here we perform simultaneous electrophysiological recordings from anterior cingulate cortex (ACC) and hippocampal CA1 in ...

This study focuses on a CFD modelling of biomass-derived syngas co-firing with coal in an older mid-sized PC-fired boiler of type OP-230 with low-emission burners on the front wall. The simulations were performed to determine whether the boiler can be retrofitted for the fulfilment of the prospective environmental protection regulations relating to...
Energy security, affordability and availability, as well as ensuring environmental sustainability are crucial considerations necessary for determining the future energy mix. The forecasted continuous use of coal in power generation and chemical industries makes it an important, yet polluting energy source. This has motivated researchers into invest...
