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.

摘要： Disclosed are cooling and depressurization system equipment, arrangement and methods to cool solid particles from a coal gasifier operating at high temperature and pressure. Ash needs to be continuously withdrawn from a circulating fluidized bed gasifier to maintain the solids inventory in the gasifier. The supports for the cooling surfaces are located on the lower temperature upper section of the primary cooler. The cooled solids along with the fluidizing gas exits the primary cooler to a secondary receiving vessel where the solids can be further cooled by conventional means. The fluidizing and entrained gas entering the secondary vessel is filtered and vented through a vent pressure control valve. The column of cooled solids in the secondary vessel is depressurized by a continuous depressurization system to low pressures which are sufficient for conveying the solids to silos for disposal.

摘要： This invention relates to a process of rearing poultry. The process comprises the steps of housing the poultry in a heated poultry shed, collecting poultry litter from the poultry shed, thermally treating the poultry litter and harnessing heat generated by the thermally treated poultry litter, and heating the poultry shed using the harnessed heat. In this way, the poultry litter may be used to heat the poultry in the shed and other expensive fuels will not have to be purchased to carry out this task, thereby reducing the operating cost of the poultry rearing process. Furthermore, the poultry litter will be available in an abundant supply. Due to the fact that the fuel is so readily available, it is possible to preheat the sheds to the ideal temperature prior to receiving the poultry and ventilate the poultry sheds both of which will result in the poultry thriving.

摘要： The invention relates to a method and an apparatus for cooling a material to be removed from the grate of a fluidized bed furnace. Material at a high temperature is passed from the grate of the fluidized bed furnace into a fluidized bed cooler in charges of a given size by measuring the quantity of the material accumulating in the fluidized bed cooler. When the quantity of the material in the cooler has reached a predetermined limit value, the supply of material into the fluidized bed cooler is prevented. The charge is cooled in the fluidized bed cooler by fluidization air and via heat transfer into a cooling liquid circulation system and the temperature of the charge is measured. The charge is removed when the temperature of the charge has fallen to a predetermined limit value. The second end (5) of a supply conduit (3) is provided with a supply valve (15) actuated by a power means (16). A discharge conduit (14) is provided with a discharge valve (17) actuated by a second power means (18). Quantity detection means (19, 20) are provided to produce quantity data regarding the amount of material in a fluidized bed space (11), and temperature measuring means (21) are provided to produce temperature data. A control device (22) controls the first power means (16) to open and close the supply valve (15) and the second power means (18) to open and close the discharge valve (17) on the basis of the quantity data and temperature data and the predetermined limit values of quantity and temperature so that the loading of material into the fluidized bed space and its cooling and removal from the fluidized bed space take place in a charge-by-charge and cyclic manner.

摘要： A fluidized bed furnace for burning dehydrated sludge, comprises a furnace housing having a bottom on which the fluidized bed is supported. Means are provided for directing gases, including combustion air, upwardly through the fluidized bed in order to reduce the sludge to fine ash dust which is carried off with a portion of the gases and also to coarse particles which are removed from the furnace bottom. For this purpose, the combustion chamber is provided with a discharge opening directly adjacent the bottom, and preferably with a bottom which is aligned with the surface of the furnace bottom. The diameter of the discharge opening is such that it will allow very large size coarse particles to pass therethrough. A rotary drum is mounted so that its one end connects to the discharge opening, and it is provided with a screw having a pitch of a size to permit coarse particles to move between blade elements and to move them out of the discharge opening into a collecting shaft where the coarse particles are dropped into a receiving device.
