Tunnel kiln was reformed according to energy-saving mode, which was energy utilization diagnosis and analysis and energy-saving reconstruction. First, thermal performance was diagnosed, and the basic data for energy-saving reconstruction was provided through the test of tunnel kiln. Then the main factors of low thermal efficiency was found .Second the thermal balance was calculated in drying and sintering process, which determined the form of waste heat recovery and utilization system. Finally the reconstruction was implemented by three energy-saving technologies .It caused energy-saving rate reached 44%.

From the view point of efficiency, the energy consumption coefficient was used as the energy utilization evaluation index in a water supply pumping system, and through the comparative analysis between the energy consumption coefficient and the pump efficiency, the past pump efficiency that was used as the economic index in the system could not completely and scientifically reflect the energy utilization rate of the system, while the energy consumption coefficient could intuitively reflect conveying unit volume of liquid consumption in a water supply pumping system. Based on the theory of energy consumption coefficient, the comprehensive analysis of different energy saving methods, energy saving space estimation, and average energy consumption coefficient calculation under variable conditions of the system in a water supply pumping system can give a specific guidance scheme of energy saving to the system, and it has a guidance and reference significance to the energy saving reform in the water supply pumping system.

This study discussed the feasibility of developing a system to circulate the heat loss from the coil and iron core of the power transformer equipped for buildings during power supply to the heat recovery unit. This study affixed a copper tube into the transformer insulating oil, allowing the water to circulate at normal temperature in the coil tube, and absorb the heat energy generated by the transformer coil and iron core. The heat energy was then recovered and stored. A low tension power transformer (7.5 KV) was used in the experiment. The operation was carried out in transforming power supply mode to seek for the most suitable recovery unit for various occasions. The test results showed that if the hot water recovery efficiency is 50%, in the course of producing hot water, the mean temperature of 17.5 L normal temperature water can be increased from 20°C to 50°C, thus producing 12.5 kJ heat only spends about 34 min. The results proved that the recovery unit for the heat from the power transformer can benefit from heating, prolong the transformer's lifetime, increase the power supply efficiency, and reduce the air conditioning load to save energy and to reduce global warming.
