On June 1, Daqing Petrochemical Company's 1.2 million-ton/year ethylene first cracker was successfully fired. The cracking furnace is the leading device of Daqing Petrochemical's large ethylene project. All imported products are used. The single-stage design processing capacity is 150,000 tons/year. The ignition high-temperature oven is the key to the operation of the cracking furnace device. The main purpose is to remove the surface free water and crystal water in the fire-resistant and heat-insulating material by slowly heating and raising the temperature. At the same time, the furnace tube is pre-oxidized through the air to prevent the furnace wall from cracking and Collapse, effectively improve the production cycle of the cracking furnace.
