Effect of the arch-supplied over-fire air ratio on gas/solid flow characteristics of a down-fired boiler

Liu, Guangkui; Chen, Zhichao; Li, Zhengqi; Zong, Qiudong; … - In: Energy 70 (2014) C, pp. 95-109

An OFA (over-fire air) program and matched measures supporting efficient-combustion are proposed for the FW (Foster Wheeler)-type down-fired boiler, where the OFA is supplied from the arches of the boiler. A gas/solid cold test was conducted at a scale of 1:15, using a two-dimensional laser...

Numerical investigation for combustion characteristics of vacuum residue (VR) in a test furnace

Sreedhara, S.; Huh, Kang Y.; Park, Hoyoung - In: Energy 32 (2007) 9, pp. 1690-1697

It has become inevitable to search for alternative fuels due to current worldwide energy crisis. In this paper combustion characteristics of vacuum residue (VR) is investigated numerically against experimental data in typical operating conditions of a furnace. Heat release reaction is modeled as...
