Abstract: The present disclosure provides a carbon-based oxygen-enriched combustion method for recirculation of flue gas from a cement kiln. The combustion method includes recirculating the flue gas generated by the cement kiln to a certain degree to concentrate and enrich carbon dioxide in the flue gas of the cement kiln, mixing the carbon dioxide-rich recirculating flue gas of the cement kiln with the pressurized oxygen to obtain the carbon-based oxygen-enriched products, and mixing the carbon-based oxygen-enriched products with the atmospheric-pressure oxygen to obtain carbon-based air which serves as combustion-supporting gas of the cement kiln.

Abstract: The present invention discloses a software reliability simulation analysis method based on virtual reality and a complex network, which realizes a two-layer network displaying the coupling of a task network and a function complex network in a virtual reality environment and is convenient for technicians to observe the operation of the network from multiple perspectives. On the basis of a technology of virtual reality, the present invention determines the task simulation based on an operation section, observes the flow of codes and the number of passing through function nodes in real time during the execution of a task, and calculates and assesses the importance degree of the nodes. The task simulation method based on the operation section is more convincing for the assessment of the importance of the nodes.
