Reburning chemistry: a kinetic modeling study

Abstract

By making use of steady-state analysis of the fault propagation behaviors in process systems, improvements of the digraph-based techniques for faultrtree synthesis have been achieved. In particular, generalized sub-tree structures have been developed for variables associated with nodes on feedforward and feedback loops and a preliminary loop-searching computer algorithm has been worked out. These techniques are integrated in a fault-tree construction procedure which is also presented in this paper. This revised procedure has been implemented in a number of application examples. The results show that the proposed approach is not only feasible but also capable of identifying correct causes of the top event which are missing in t

COMPUTATIONAL MODELING AND EXPERIMENTAL STUDIES ON NOx REDUCTION UNDER PULVERIZED COAL COMBUSTION CONDITIONS

“…This is very similar to that of Kilpinen et al (1992). While constant efforts were made to update this mechanism based on the most recent literature, the preliminary runs on reburning with methane showed promising results.…”

Shock tube determination of the overall rate of NH2 + NO → products in the thermal De‐NOx temperature window

“…combustion systems. In these processes, the reaction of NH 2 with NO plays an important role, and this reaction has two major product channels [1,2]. One is a chain branching channel…”

Estimation of reburning potential of syngas from sewage sludge gasification process

“…Several kinetics models have been reported to describe the reburning process with different levels of details and predictions (Bilbao et al, 1995;Dagaut et al, 1998;Galborg et al, 1998;Klipinen et al, 1992;Miller and Bowman, 1998;Smith et al, 1998;), providing an overall understanding of the interaction among hydrocarbon and nitrogen species.…”
