Based on analysis of five different conditions’ full scale model tests of the fastener tubular steel scaffolding, the paper introduces that notional lateral loads can imitate the effect which generalized imperfections of the falsework(initial imperfections, node semi-rigid and so on) give the bracket’s stability capacity. According to the finite element software ANSYS, the falseworks’ stability capacities of different conditions have been imitated and analysed, Analysis results compare with test results. The final result indicates that it is reasonable that notional lateral loads in certain scope can imitate generalized initial imperfection. Research results can be used for on-site t technical personnels’ design and safety control.
Using combustion theory to research on the technical theoretical features of oxygen-enriched combustion technology application to the cement industry kiln. On the basis of this, engineering projects of that, a certain enterprise 3000 t/d cement clinker production line applied oxygen-enriched combustion technology, and its economic evaluation were calculated. The results showed that: applying Oxygen-enriched combustion technology to the existing cement clinker calcined equipments, the coal powder consumption, the volume of flue gas and CO2 concentration in the flue gas of unit cement clinker occurred regular changes, When the O2 concentration increased from 21% to 30%, the coal powder consumption decreased by 17.78%, the flue gas volume was reduced by 12.73% and the CO2 concentration in the flue gas increased to 76.57%. If the enterprise used the oxygen-enriched atmosphere of O2 concentration for 30% to form the coal combustion, it can save coal about 71.87 t/d, equipment production capacity increase by 41.75% and capture CO2 products about 2662 t. Every year, this resulted in the profit increasing 103 million yuan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
