Comparison and selection on capacity expansion and speed increasing modification scheme in section of Panzhihua to Yuanmou in ChengduKunming railway line

The main problems of LKJ-93 train operation monitoring and reconding device in operation were presented,and based on the operating principle of JZ-7 air brake a practical modification scheme for existing train operation monitoring and recording device was proposed.

The modification scheme of reclosing breaker circuit in an 110kV unattended substation was presented compared with the original scheme.

The new transformation scheme of the pump station uses the technique of the pump-contr.

After the covering of CATV in the villages,a disputation occurs to the villages belonging to the villagers committee,that is which scheme is better,optical fiber cable or electric cable? In view of the characteristics of HFC network in Songming County,this paper conducts checking calculations according to the related data of village HFC network transformation scheme,and then comes to a conclusion.

This paper analyzes and demonstrates the technical performance,technical characteristics and economic benefits of different transformation schemes for mine ventilation,and based on the the analysis and demonstration results,points out that the ventilation transformation scheme of changing the compound ventilation into division ventilation is feasible.

Analysis of external procedure and assessment of retrofit scheme of heat recovery area in Xiahuayuan power plant s HG-670/140-9 s boiler;

To solve these problems,two retrofit schemes,with which relevant pollutant emission standards can be satisfied,are being put forward for ESPs of currently Zhungeer coal-fired power plants.

Based on the cause analysis,three retrofit schemes are presented in this paper such as adding electric fields,retrofitting to bag filters and to advanced hybrid particulate collectors.

Production situation of Dongtan coal preparation is introduced A reformation scheme is put forward based on to examine and to verify the production capacity of various systems and determined the comprehensive production capacity.
