摘要： Disclosed is a fluidized bed system which includes a fluidized bed reactor, a solids separator and a return line and serves to carry out exothermic processes in a circulating fluidized bed for large thermal capacities. Secondary gas is introduced into the reactor on a level which is at least 1 meter above the bottom of the reactor. The fluidized bed system is provided with one or more displacing bodies, which cover 40 to 75% of the bottom surface area of the fluidized bed reactor and have a maximum height that is equal to one-half of the height of the reactor to ensure a satisfactory transverse mixing of the oxygen-containing secondary gas and fuel in reactors having large dimensions.

摘要： Disclosed is a process for burning cattle dung at a temperature of from 500.degree. to 780.degree. C., preferably from 650.degree. to 780.degree. C., in the presence of one or more aluminum-containing substances selected from the class consisting of bauxite, kaolin and aluminum compound-containing ash from furnaces for firing solid fuels. A major part of the alkalies contained in the cattle dung and a substantial part of the chlorine are retained in combined form in the resulting furnace ash.

摘要： Disclosed is an apparatus and process for an energy producing plant utilizing a circulating fluidized bed system having an integral fluidized bed heat exchanger, the fluidized bed reactor and integral heat exchanger having a common wall with at least one perforation for fluid communication therebetween. In the system, solids are separated from the reactor flue gas, and in dependence upon a process variable, are directed in varying amounts either directly back into the reactor or into the integral heat exchanger, the latter being operated as a classical and/or bubbling bed at a higher pressure than the reactor. A heat exchange medium passes through tube bundles immersed in the exchanger fluid bed and the bed solids and fluidizing gas in the heat exchanger are passed through the perforation to control the reactor operation. Because of its structural integrity this system allows for greater flexibility in control and aids in turndown operations as well as controlling variations experienced under otherwise constant load conditions. The system and arrangement find use both in utility plants and process operations.
