Based on the engineering statistics method, the designed furnace parameters are obtained from the 600-MW and 1 000-MW boilers with tangential firing and wall firing. The power and arrangement of the burners are analyzed. Their impacts on slagging on heating surfaces and the carbon contents in the ash and cinders are also discussed. Thermal parameters of furnace are recommended for boilers of 600 MW and 1 000 MW firing slagging coal in the design. The static or rotary classifier should be the first choice for the pulverizing system.展开更多

Content of MgO in the slag of pyrometallurgical separation of boron from iron is much higher than that in the ordinary slags. Through the equilibrium partition ratio of sulfur L S between the metal and the slag in an atmosphere of CO N 2, the acidic coefficients for B 2O 3 and the basic coefficients for MgO were estimated. The basic formulae were given for the blast furnace type slag containing B 2O 3 and high MgO.展开更多
Summarizes the processes and development of Baosteel slag processing techniques such as the instantaneous slag chill (ISC) process, the tank-type hot disintegrating process and the rotary drum process. A detailed in...Summarizes the processes and development of Baosteel slag processing techniques such as the instantaneous slag chill (ISC) process, the tank-type hot disintegrating process and the rotary drum process. A detailed introduction of the slag comprehensive utilization at Baosteel is given. The details of Baosteel' s comprehensive utilization in the fields of simering materials, returned slag for steelmaking, road construction, cement production, mixed concrete, new construction materials, ground-filling materials and reinforced material for soft earth are given. Emphasis is placed on source management and ensuring that from both organizational and managerial perspectives, Baosteel' s slag processing techniques are safe and energy-saving, thus constantly demonstrating the issue of sustainable development.展开更多
