It has 16 vertical holes and can be combined horizontally and vertically for getting better combusion. Using combined-briquet in small boilers can decrease the amount of smoke and dust and save energy. This paper describes the combustion characteristic of the cornbined-briquet from its structure, combustion process to strength and combination form to match the briquet with boilers better.展开更多

The techniques of high speed Schlieren photograph, pressure measurement and so on, are used to study the influence of rarefaction wave on the laminar flame propagating through methane-air mixture. The results show that, after the rarefaction wave acts on the propagation laminar flame, the laminar combustion is fully transformed into turbulent combustion just during several milliseconds, which leads to a sharp increase in the burning surface area and the pressure rise rate.展开更多
