SHX circulating fluidized bed(CFB) hot water boiler is a new generation of low speed internal circulating fluidized bed(CFB) hot water boiler. While inheriting the advantages of the original technology, vortex fluidized combustion technology, vortex wind separation structure design, parametric design technology, and material return technology have achieved major technological breakthroughs and are national patent products. In the separator structure, it increases the spiral guide to extend the inlet acceleration section of the separator to improve the separation efficiency of the separator, make up for the lack of combustion of coal particles in the furnace, and improve the combustion efficiency. It adopts a membrane type water-cooled wall to cleverly arrange the furnace, separator and return system into a single unit, and has a compact structure.

Working Principle Of SHX Circulating Fluidized Bed Boiler(CFB)

SHX Circulating Fluidized Bed(CFB) Hot Water Boiler

Coal and air enter a fluidized combustion chamber, mixing and ignition combustion, forming dense phase and dilute phase area of the burning material in the furnace, plus two air inlet pipes in the upper part of the dense phase area, making the material more fully burning, in favor of the boiler load regulation. According to the different kinds of coal, the proportion of the general one or two times air is 7:3 or 6:4. The solid material with a large number of fine particles is separated from the solid material in the gas-solid separator after the furnace outlet, and the flue gas enters the tail heating surface, and the separated materials are sent back to the main fuel through the return device. The burning chamber is reburning. Until the combustible matter contained in coal is released.

Performance Advantages

  • 1, the membrane water wall is used to make the furnace, separator and return system skillfully arranged into one body, and the structure is compact.
  • 2, Significant breakthroughs have been made in the structure and parametric design of the separator, which has effectively improved the combustion efficiency and separation efficiency of the boiler.
  • 3, The return track of the feed back system consists of two film type water cooling walls. Some of the heat energy carried by the fly ash is absorbed by the water cooled wall tube, and the fluidized bed boiling flow is used to inherit the Rematerial device to realize the boiling flow state of the return material.
  • 4, a number of measures are adopted in the anti-wear design, the adaptability of the burning coal is wide, and the whirlpool flow combustion technology realizes the circulation combustion of the material in the swirl flow in the combustion chamber, and improves the combustion efficiency. In addition, the failure rate can also be reduced, and it can run continuously for a long time.
  • 5, the product uses low-temperature combustion technology, effectively reducing the formation of harmful gases, desulfurization can be carried out in the furnace, in line with national environmental protection, energy saving and emission reduction policies.
