Studies of ignition behaviour of biomass particles in a down-fire reactor for improving co-firing performance [PDF]
, 2016 To realize large percentage biomass co-firing with coal in existing coal-fired boilers, the combustion behaviour of biomass is expected to be similar or comparable to that of coal. When co-firing with coal, biomass is not necessarily to be ground as fine

Ignition characteristics of nitromethane-doped ethanol in a heated shock tube
Energetic Materials Frontiers, 2021 Ignition delay times of nitromethane-doped ethanol dual fuels are measured under the micro-combustion engine conditions (8 × 105 Pa and 904–1477 K). The promotion effect of nitromethane on ethanol ignition is more pronounced at a fuel-lean condition;

The mechanism of char ignition in fluidized bed combustors [PDF]
, 1987 Knowledge about ignition processes of coal in fluidized beds is of importance for the start-up and dynamic control of these combustors. Initial experiments in a transparent fluidized bed scale model showed the existence of a considerable induction period
