In addition, a hybrid numerical simulation of solidification process over the whole metallurgical length of caster has been executed with the two mathematical models and a relevant secondary cooling scheme has been worked out.
The result proves it's feasible for the scheme of stator and rotor air-cooling for large hydro generator of Xiaowan which unit capacity is 700MW. It meets the need of long-term service for unit with safety and stabilization completely.
On the basis of relevant theory, through some programs of the second cooling water, optimizing the plan for the second cooling technology parameters of 319×410 strand and supplying reference for producing the same type quality steel, a contrast test is made.
On the basis of comparison of the economic benefit between the ice cold storage scheme and the routine air conditioner refrigeration scheme for some office building the paper explains the feasibility of the ice cold storage in construction projects.
This paper presents a comprehensive introduction and a review for the property of an air-cooled scheme,the design condition of an aiρ-cooled steam turbine,and its design characteristics and the requirements and the countermeasures for the safe running. It can be referred for the design of the air-cooled steam turbine.
The observed spectra were found to be substantially dependent on the transition under study and the frequency of a repump laser used in the cooling scheme.
In this paper, the author presents his three chief researches about the water-cooling of electrical machines. 1. In 1958, for the first time, the author proposed the plan of inner-water cooling of the rotor winding of synchronous generator, and in the same year, under the leadership of our party, the first double-sided inner-water-cooled synchronous generators in the world were produced in China. 2. In early 60's, the author devised some new schemes to use the "Watcr-water-air" cooling technique instead of ...
