Static Characteristics of Limestone Calcination


Volume 13 (Total 77) Thermal Power Project in September 1998 No. 2f-{z quartz sand and rice hull and the flow of coal particles (Thermal Power Engineering, Zhejiang University) Eagle Star Huang [Abstract] trial in the small dark stage of the rice husk fluidized bed boilers were glistening wide study. Yao cats, cat Yao and sand, rice husk and sand court battlements and other maggots were glistening shaft of the well characteristics and glistening temple properties were surgery related social boats t Farm, was |} 『a guide intended to have real bad Qian Jing Yao a mantis. Yao Bin said the cat for the fluidized bed combustion boiler design and operation of a static basis and guidance for management experience. Keywords Lv shell Luk Luk of the characteristics of mixed platform bed features in the circle classification TQ038l1. ; I} i Foreword u \ as traditional energy resources (coal, oil, gas) reserves are depleted as a result of its extensive use of serious environmental pollution, development and utilization of renewable energy resources as well as recommend stained smaller, even cast a new, cleaner energy sources has become an urgent problem in today's world. One of its renewable biomass energy, low pollution, economic convenience attracted the attention of the world. In the biomass energy distribution. Has abundant rice husks, transmission simple and easy pretreatment, the distribution is relatively concentrated, easy to use features of lining, and the husk of sulfur, chlorine content is not high. Environmental pollution when burned. Therefore, low-pollution combustion of rice husk and efficient use of digging into a research concern. Fluidized bed boiler furnace pit with the accumulated heat load, the combustion process a strong disturbance, the fuel in the furnace the advantages of long residence time can burn out very well the characteristics of elbow length Min. In addition, timely supply of rice husk can not elbow, it can be good she achieved and other fuels (eg coal) firing, so the glistening of the bed combustion of rice husk has become the current technology of choice for burning rice husk, and glistening with mixed sets of characteristics just fluidized bed combustion technology is based on rice husk. 2 hull shape of the characteristics of rice husk boat, about long-9mm, Width 3mm, shell thickness 0.2mm. The surface of the burr, extremely smooth, easy to produce particles jam pits, bridges, poor mobility, are difficult to glistening of the media. The composition of rice husk and other quality wood as Ao. Cable from the wood,[link widoczny dla zalogowanych], booths f dimensional,[link widoczny dla zalogowanych], semi-ting f cellulose, whose guitar depends on the growth of rice varieties and its environment. Rice husk and other agricultural waste materials in the technical quality of cut is the largest district in the amount of ash guitar almost pure Sio. And a small amount of K, P and other elements. Packing density and real density of rice husk very different, to transport and transport caused great difficulties. Rice husk used in this experiment the physical parameters shown in Table 1. Huan a series of physical parameters hub shell 2) static calcination of limestone, particle size and specific surface area of CaO little effect on the average pore size. Therefore, coal desulfurization,[link widoczny dla zalogowanych], desulfurization chain furnace calcined limestone in the static case,[link widoczny dla zalogowanych], coarse limestone particle size can be an appropriate number, in order to save operating costs} (3) not only the sintering of limestone calcination temperature plays an important role, and calcination residence time in the calcination temperature is higher, also plays an important role.
