Abstract:

Taking Changguang high-sulfur coal and Yanzhou low-sulfur coal as experimental coal types, carrying out the experiment of Q-phase cement clinker co-generated from coal on two-stage polyphase reaction setup and conducting XRD analysis on the mineral composition in co-generation clicker sample, the result shows that the major mineral species in compositions of co-generation clinker are 2CaO•SiO2 and Q-phase. Taking one 330MW machine set 1004 (t.h-1) pulverized coal combustion boiler as analysis object, this paper carries out the preliminary analysis of the economic benefits that it may bring to power plant and cement enterprise by using co-generation technology. The analysis indicates that the objective boiler adopting belite Q-phase cement clinker technology, on the whole estimate of the resourceful benefit of coal fly ash and SO2 emission reduction benefit, the economic benefit of power plant obtained is 25,870 thousand yuan per year. The economic benefit cement enterprise obtained by using Belite Q-phase cement clinker to advance capacity is 40,581 thousand yuan per year.
