Embodiment approach
[0022] As an embodiment of the present invention, the outer wall of the boiler 3 is provided with an insulating layer, which can ensure the temperature inside the boiler 3 during operation, reduce the consumption of thermal energy, and make the combustion in the boiler 3 more complete.
[0023] As an embodiment of the present invention, the first water tank 34 is separated from the boiler 3 only by a stainless steel plate. The stainless steel plate has the characteristics of good thermal conductivity and is not easy to corrode, which can ensure that the first water tank 34 is fully heated.
[0024] As an embodiment of the present invention, the surface of the first water tank 34 is provided with an insulating layer to reduce heat energy loss and make full use of heat energy to generate water vapor.
[0025] As an embodiment of the present invention, the beating shaft 54 is made of high temperature resistant soft material, which can prevent excessive vibration from damaging th...

The invention belongs to the technical field of boiler equipment and in particular relates to a circulating fluidized-bed boiler. The circulating fluidized-bed boiler comprises a coal supply pipeline,a hot air supply pipe, a boiler and an air chamber, wherein the two air pipes, which penetrate through the bottom of the boiler and are communicated with the air chamber, are fixedly arranged in theboiler; the air pipes are hollow and a plurality of air outlet holes are formed in the surfaces of the air pipes; the plurality of air outlet holes are arranged so that airflow in the boiler is convenient to flow and the combustion is more sufficient; an impacting shaft, which is fixedly connected to an impacting rod, is arranged between the impacting rod and a second water tank; the impacting rodis in contact with a vibration rod; when the vibration rod is vibrated, the impacting rod which is in contact with the vibration rod is vibrated, so that the vibration rod, the impacting rod, the second water tank and an airbag are combined to promote vibration; a third spring and a connection rod are arranged and the second water tank is impacted through the impacting shaft, so that dust on thesurface of the second water tank is removed and the heating of the second water tank is more sufficient; the plurality of water tanks are arranged, so that heat generated in a boiler combustion process can be sufficiently utilized and water is evaporated into water steam; the circulating fluidized-bed boiler can be used for desalting seawater, boiling drinking water, generating power by thermal energy and the like.
Description
technical field [0001] The invention belongs to the technical field of boiler equipment, in particular to a circulating fluidized bed boiler. Background technique [0002] Circulating fluidized bed boilers use circulating fluidized bed combustion technology, which has the advantages of high efficiency, cleanliness and low pollution, wide use of fuel, and high utilization rate of ash. Therefore, circulating fluidized bed boilers are widely used in power plant boilers and waste incineration fields. [0003] Circulating fluidized bed combustion technology is a clean coal combustion technology developed in the past two decades. Because of its wide fuel adaptability, high combustion efficiency, low nitrogen oxide emissions, low-cost limestone furnace desulfurization, large load regulation ratio and The outstanding advantages such as fast load adjustment have been widely used in the world, and large-capacity circulating bed boilers have been accepted by the power generation indust...
