cement production. The main physico-chemical processes taking place in the calciner are coal combustion and the strongly endothermic. calcination reaction of the raw materials. In this paper a
Cement Rotary Kiln Coal Combustion Energy & Fuels, Vol. 20, No. 6, 2006 2351. precalciner is about 85-95%. After it enters into the rotary kiln, the feed is heated by the gas with high temperature and the wall of kiln, and the decomposition reaction proceeds. In this zone, there
Jun 25, 2016 In this paper, a comprehensive computational fluid dynamics (CFD) methodology was adopted to investigate the characteristics of oxy-coal combustion in a cement kiln with a specially designed burner. The simulation was conducted under five oxidant stream conditions with different O 2 /N 2 volume ratios: 21/79, 24/76, 27/73, 30/70, and 33/67. The
Process in Cement Kiln. In the cement plant, the Pre-calcined raw material is supplied to the rotary kiln where a series of physical and chemical reaction (combustion) take place to form the clinker. After that, Hot clinker is sent to the cooler. The energy required for clinker formation is achieved by burning fuel (coal, oil, gas) at the
Sep 01, 2001 Blended coal that consists of 70% anthracite and 30% bituminous coal is cheaper than pure bituminous coal, but it is very difficult to burn in the rotary cement kiln. To burn the blended coal, a new kind of burner, which is called the burner with velocity difference jets, is used to intensify combustion.
