http://www.sciepub.com/reference/192144 WebIn a slow combustion fireplace, jets of pre-heated air provide oxygen to the area just above the baffle, igniting impurities from the wood and capturing heat that normally escapes up the chimney. Using less firewood means less ash is produced and it also means less cleaning.

WebThe transition from combustion to explosion is caused by an acceleration of the reaction, induced either by a rise in temperature or by increasing lengths of the reaction chain. The first is called thermal explosion, and the second is called chain explosion.

A proposal for the self-healing nature of Pt–Pd catalysts is shown in Figure 9. The PdO traps mobile PtO 2, and as the concentration of Pt builds up, it can transform the oxide into a metal phase. This we feel is the origin of Pt–Pd on one face of the particle, coexisting with PdO.
