Municipal Solid Waste Incineration (MSWI) fly ash was successfully used as raw material in sintering Alinite cement clinker in the laboratory. In this paper, formation progress of Alinite cement clinker, influence of gypsum on the hydration of alinite cement, hydration heat release rate, hydration product and its microstructure were studied. Results show that Alinite cement clinker can be sintered by using MSWI fly ash as a major raw material. During the sintering,  C₂S, C₁₂A₇ and C₂S·CaCl₂ was presented first,then make alinite cement clinker when react with MgO, CaCl₂. Addition appropriate amount of gypsum can improve the early compressive strength and accelerate the hydration rate of Alinite cement, and the Alinite cement can be utilized as a kind of early-strength and rapid-hardening cement; Hydration product of Alinite cement not only includes CSH gel, AFt with clavate shapes and CH crystals which can be observed in Portland cement, but also has C₃A·CaCl₂·10H₂O crystals.

On the basis of fuzzy mathematic theory, a comprehensive evaluation method was developed to evaluate the general arrangement of cement plant quantitatively. Evaluation index about the general arrangement of cement plant was described in 6 aspects: technological process, general arrangement, transportation， ground development, natural condition, facility application. A multi-level evaluation index system was established, and the weight of each level index was determined. The construction project of Nanyang Pingmei Tianrui Cement Ltd. was taken as a typical case，general arrangement schemes were compared and analyzed, the result shows complete agreement with actual situation. The method can be used to assess the general arrangement of cementplant quantitatively and make decision among different schemes.

Based on experimental analysis about water-resistance mechanism of MOC(magnesium oxychloride cement) and MOC products, it has been determined that residual MgCl₂ is the essential cause resulting in the poor durability． And various kinds of Cl^－ ion catchers have been applied to improve MOC, in among that β-A catcher has the best behavior． This result has quite wide application foreground．

The structure and principle of four-channel coal burner was presented in this paper. The common problems of four-channel burner created during operation was described by the author. In view of this issue, suggestions are put forward by the author in order to solve the matter.
