摘要： A circulating fluidized bed (CFB) boiler has one or more bubbling fluidized bed enclosures containing heating surfaces and located within a lower portion of the CFB boiler to provide an in-bed heat exchanger (IBHX). Solids in the bubbling fluidized bed are maintained in a slow bubbling fluidized bed state by separately controlled fluidization gas supplies. The beds feature open bottom distribution grids with hoppers disposed below to collect solids. The enclosure defining the IBHX is supported from structures below the grids and the enclosure can be supported from the hoppers.

摘要： The invention relates to a fluidized-bed reactor having a higher power density and to an exchangeable insert for said fluidized-bed reactor, which insert makes the higher power density possible. The supply and pre-heating of the fluidizing agent, especially air, to the fluidized bed is combined with the cooling of the reactor vessel wall owing to the preferably exchangeable insert in the fluidized-bed reactor. The “cold” fluidizing agent is guided in at least one flow channel in the metal jacket surrounding the fluidized bed and is preheated and said channel and is then injected into the fluidized bed in an appropriate location. The reactor vessel wall is cooled by pre-heating the fluidizing agent. The desired and required values for cooling the reactor vessel and the desired pre-heating of the fluidizing agent can be adjusted by suitably selecting the parameters ‘length’ and ‘volume’ of the flow channels in the insert and the flow rate of the fluidizing agent in the flow channels. The insert is used for supplying the fluidizing agent and for cooling the reactor vessel, thereby eliminating the need for a separate cooling device for the reactor vessel and for lining the reactor vessel with refractory clay. The reactor vessel according to the invention is compact, has a high power density and small thermal masses.

摘要： A circular fluidizing bed combustion system with uniform airflow distributing device is provided. The system comprises a fluidizing bed and a uniform airflow distributing device. The fluidizing bed is comprised of a fluidizing bed boiler body, an airflow distributing plate and a plurality of air caps, wherein, the airflow distributing plate is provided inside the fluidizing bed boiler body and divides the inner space of the fluidizing bed boiler body into a fluidizing chamber which is located in the upper portion of the boiler body and an air chamber which is located in the lower portion of the boiler body, and the plurality of air caps are arranged on the airflow distributing plate for injecting the fluidizing air into the fluidizing chamber. The inner space of the air chamber is divided into a distributing chamber that is located under the airflow distributing plate and an air inlet chamber that is located on one side of the distributing chamber by means of a perforated plate. The distributing chamber is comprised of a front wall, two side walls, a top wall that extends upwards obliquely from the upside of the front wall, and a bottom wall extends downwards obliquely from the downside of the front wall. A first guide plate, a second guide plate and a third guide plate are installed in the distributing chamber. This system makes the flow of the fluidizing air entered into the fluidizing chamber through each air cap uniform, and enhances the combusting efficiency of the coal powder in the fluidizing chamber.
