In this thesis, the production, development and operating principle of explosive devices are introduced; the classical electric-thermal theory and computer modeling of bridgewire explosive devices are expatiated; the connection between the no-firing currents or temperature and electric-thermal parameters is discussed.

The main purpose of this thesis is to perform the thermal testing for three mainparts of heating system with the methods of energy and exergy balance, based on theheating system of Da Li tobacco plant in Yun .

Based on the thermal measurements and the characteristics of equipment,process and operation,heat utilization status of the chain grate of Shougang Mining Company grate-kiln system is analyzed and diagnosed.
