At 22:00 on May 1, 2022, the ultra-high pressure waste heat boiler with reheat function for coke dry quenching, independently developed by Xizi Clean Energy Equipment Manufacturing Co., Ltd. (formerly Hangzhou Boiler Group), was officially put into operation at Guangxi Shenglong Metallurgy Co., Ltd. in Fangchenggang City. This type of waste heat boiler represents the third-generation product developed by Xizi Clean Energy based on its second-generation high-temperature and high-pressure technology. Its overall efficiency has increased by 13%. It is the world’s first and most efficient waste heat boiler designed for coke dry quenching. Construction on this project began on April 1, 2021. Through careful planning and precise execution by all parties involved, it entered the phase of joint testing at the end of April this year, and was successfully put into operation on May 1. Compared with conventional high-temperature and high-pressure waste heat boilers, based on an annual operation time of 8,000 hours, the annual electricity generation increases by 33.6 million kWh, the annual revenue from electricity generation rises by 16.8 million yuan (at 0.5 yuan/KWh), and approximately 4,100 tons of standard coal are saved annually. The successful commissioning of this project will lead to the efficient use of secondary energy in the coking industry, ushering in a new era of low-carbon and environmentally friendly practices. Since the 1980s, when Xizi Jieneng designed and manufactured China’s first set of dry quenching waste heat boilers with a quenching capacity of 75 t/h for Baosteel, it has developed a range of such boilers with quenching capacities ranging from 75 t/h to 270 t/h, featuring both natural circulation and forced circulation systems. The company also offers a full range of dry quenching waste heat boilers operating under medium temperature and pressure conditions, as well as under conditions of high temperature and pressure, ultra-high temperature and pressure, as well as dual-pressure settings. As of April 2022, Xizi Clean Energy had produced over 260 sets of dry quenching coke waste heat boilers, holding a comprehensive market share of more than 60%.
