Chemical energy carriers are crucial for addressing challenges that arise from time lag,
large distances, and temporal fluctuations in renewable energy production, which lead to …

Co-firing ammonia in coal units is a promising approach for the phasedown of coal power. In
this paper, we demonstrate the feasibility of burning ammonia with coal and biomass in a 25 …

Coal is an important fossil fuel, a resource primarily used for electric power generation, and
currently supplies 41% of global electricity needs. Fossil fuel is one of the demanding …

A large amount of alkali and alkaline earth metal species (AAEMs) are contained in sewage
sludge (SS) ash, which will affect the combustion characteristics and synergistic effects of …

Abstract Zero-carbon fuels (H 2/NH 3) replacing coal co-firing is a promising way to address
carbon emissions. Hydrogen co-firing helps improve combustion stability at low loads and …

Owing to coal commonly existing in a fluctuating thermal environment, a two–step parallel
reaction model for coal ignition was established to explore the development of coal ignition …

This work focuses on single particle ignition behavior of biomass fuels. Five biomass fuels
were studied, namely, wheat straw, kiwi branches, vine branches, sycamore branches and …

Abstract O 2/H 2 O pre-oxidation could be regarded as a promising approach for clean and
high efficiency utilization of high rank coals. A typical anthracite was employed for …

Coal after thermal decomposition has high reactivity and can easily self-heating and self-
ignite. The spontaneous combustion problem of thermally decomposed coal has been …

In biomass harvesting and fuel preparation processes, grinding causes a prominent energy
consumption penalty, which results in an analogous cost impact. This is due to the fibrous …
