Problems solved by technology
[0002] In the existing fluidized furnace production line, when the raw materials are burned in the combustion chamber, the induced draft fan will suck the burned raw materials into the furnace. Due to the gravity of the raw materials, some raw materials will fall to the bottom of the combustion chamber, and a large amount of residue will be accumulated in the combustion chamber after a period of use. The bottom of the combustion chamber makes the raw materials sucked into the furnace burn insufficiently, resulting in a large amount of black smoke during the combustion process

Embodiment Construction
[0013] The present invention will be further described below with specific embodiments in conjunction with the drawings, see Figure 1-2 ;
[0014] The biomass burning boiling furnace system includes a feeding port, a hoist, a silo, and a boiling furnace. The boiling furnace includes a combustion chamber, a furnace and an induced draft fan. The raw materials are transported from the electric hoist to the feeding port, and then transported to the silo by the elevator. The dragon transports the raw materials to the combustion chamber, which is connected to the furnace. The induced draft fan guides the flue gas generated after the raw materials are burned from the combustion chamber and the furnace to the flue gas pipe, and the flue gas pipe is connected to the water foam dust removal device.
[0015] The combustion chamber is provided with a feed end, which is connected to the silo. The feed end is equipped with a blower and a waste heat recovery fan. The air supply part of the blowe...

The invention discloses a fluidized bed furnace system for biomass combustion. The fluidized bed furnace system comprises a feed port, an elevator, a stock bin and a fluidized bed furnace. The fluidized bed furnace comprises a combustion chamber, a furnace hearth and an air induction fan. Raw material is conveyed to the stock bin from the feed port through the elevator, a screw conveyer in the stock bin conveys the raw material to the combustion chamber, and the combustion chamber is communicated with the furnace hearth. The air induction fan guides smoke generated after combustion of the raw material to a smoke pipeline through the combustion chamber and the furnace hearth, and the smoke pipeline is connected to a mist dust removal device. The combustion chamber is provided with a feed end, an air blower and a waste heat recovery fan are arranged at the feed end of the combustion chamber, the air direction of the air blower and the air direction of the waste heat recovery fan are combined with the air direction of the air induction fan, and therefore the raw material in the combustion chamber is combusted in the combustion chamber in a continuous rotation mode and is conveyed into the furnace hearth, little raw material falls to the bottom of the combustion chamber in the combustion process, combustion is more thorough, and black smoke can be avoided after long-term use.
Description
Technical field [0001] The invention belongs to the technical field of new energy, and specifically relates to a biomass burning boiling furnace system. Background technique [0002] In the existing fluidized bed furnace production line, when the raw materials are burned in the combustion chamber, the induced draft fan sucks the burned raw materials into the furnace. Due to the gravity of the raw materials, part of the raw materials will fall to the bottom of the combustion chamber. After a period of use, a large amount of residue will be accumulated in the furnace. At the bottom of the combustion chamber, the raw materials sucked into the furnace are not fully burned, resulting in a large amount of black smoke during the combustion process. Summary of the invention [0003] The purpose of the present invention is to provide a biomass combustion boiling furnace system. A blower and a waste heat recycling fan are arranged at the feed end of the combustion chamber. The wind directio...
