Analysis System

Based on the characteristics of high power diesel engines’ thermal balance analysis, a diesel engines’ thermal balance test and analysis system is developed through dealing a large number of test data. This system can real time monitor the temperature, pressure and flow rate of the components in cooling circuit, fuel circuit and gas circuit, can continuously record and store the state parameters, can realize theory computation, statistical analysis, query, and print data report. Also the system can realize remote operation. This system has already been operated in several enterprises. Results show that the system can estimate diesel engines’ thermal balance effectively. According to the analysis results, diesel engines’ designers can estimate the components that bearing excessively high thermal load and can solve the thermal balance problem of high power engines.

Molybdenum Concentrate

Technical analysis was used to analyze the roasting of molybdenum concentrate on the basis of thermal balance test of rotary furnaces used for Roasting, and the results indicate that, on the condition of commercial production, the Roasting of MoS2 can occur spontaneously because the heat of reaction is so much that proper cooling measures should be adopted in case overheating happens. According to above analysis, carbon-free roasting technology of molybdenum concentrate was proposed in this paper. The results, which come from thermal balance test and technical analysis of rotary furnaces used for carbon-free roasting of molybdenum concentrate, indicate that outer heat source used in traditional Roasting technology is not needed in carbon-free roasting technology, because enough heat is generated during Roasting to ensure spontaneous reaction. In fact, heating is not needed in operating process except at the beginning, to make molybdenum concentrate catching fire, and when reaction completing, to remove residual sulphur. The technology in this paper is obviously advantageous in aspects of energy saving, output, quality of production, heat loss, the concentration of SO2 in flue gas, etc. and will have remarkable environmental benefits, economic benefits and social benefits.

Full Analysis

The thermal deformation of reflecting optical system in the ambient temperature affects the system performance greatly. Based on the results of thermal balance test, the paper has made a full analysis to the deformation of reflecting optical system on the high-low temperature using the finite elemernt method,so as to validate whether the optical system meet the requirement of optical image design and temperature. This method can combine the thermal optical analysis and thermal balance test data effectively ,and therefore the most actual thermal optical anslysis model can be obtained to guide the concept and optimization of reflecting optical system.
