According to Zhang Hua, deputy general manager of Guangzhou Port Group Co., Ltd., this technology was jointly developed by Guangzhou Port Group and the Water Transport Science Research Institute of the Ministry of Communications. This technology uses the energy-saving working principle of the speed-regulating diesel engine, that is, the RTG changes its original operation. Diesel engine mode, under the control of energy conversion system and intelligent management system, automatically recognizes the load size, controls the diesel engine speed in the whole process, and outputs the electric energy that meets the load demand power, so that the diesel engine always works in the most economical condition to achieve the best fuel economy. rate.
This technology has been effective since the on-site experimental operation and commissioning at the Nansha Port Container Terminal in Guangzhou Port in May this year. After half a year of operation monitoring, the oil saved was 44.7%. The operation performance of the entire RTG was stable and normal. After the nationally recognized energy-saving testing authority tested, the overall fuel saving rate reached 42.3%. At present, this technology has been approved by the National Patent Office for patent and intellectual property protection.
Annual fuel saving of 335,000 yuan
According to experts' estimates, the port RTG speed-regulating diesel engine super-energy-saving generator set can save fuel costs of 335,000 yuan per unit per year. According to the calculation of container port of Guangzhou Port this year, the container transportation will exceed 11 million TEU, which can save 6.8 million liters per year. Fuel cost savings of about 42 million yuan, reducing carbon dioxide emissions by 20,000 tons.
Jiang Qian, chief engineer of the Ministry of Transport, who participated in the appraisal, believes that the current national ports have achieved energy conservation and emission reduction through technological transformation, and this technology energy saving of more than 40% is a big breakthrough, with a broader promotion prospect.
Wood Pellet Machine is mainly used for produce wood pellet, the material are widely, such as straw, peanut shells, wood chips, rice husk, cotton stalk, cotton seed hull, weeds and other crops straw and factory waste, lower bonding rate, difficult to molding material granulation, also can be applied to bio bacterial manure, organic fertilizer and compound fertilizer granulation in low temperature.
