Front feeding system of biomass power plant furnace

Abstract

The invention discloses a front feeding system of a biomass power plant furnace. The system comprises a feeding bin, a first level horizontal feeding mechanism and a second level horizontal feeding mechanism, wherein the first level horizontal feeding mechanism is arranged at the bottom part of the feeding bin; the second level horizontal feeding mechanism feeds to an incinerator; the first level horizontal feeding mechanism and the second level horizontal feeding mechanism are communicated through a vertical chute; a biomass bin kick-off device is arranged above the first level horizontal feeding mechanism at the lower part of the feeding bin; the first level horizontal feeding mechanism is composed of a plurality of first level axle-free spiral feeding machines which are arranged in parallel and are driven by a motor; the outlet of each first level axle-free spiral feeding machine leads to the inlet of the vertical chute; the outlet of the vertical chute leads to a feed inlet of a second level axle-free spiral feeding machine; and the biomass bin kick-off device comprises a plurality of biomass spiral kick-off feeding shafts which are arranged in parallel. According to the invention, crushed biomass is uniformly and smoothly input in the incinerator, and is enabled to burn and generate electricity fully, and the system is energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to a feeding system in front of a furnace of a biomass power plant. Background technique [0002] Biomass power plants send the crushed biomass to the incinerator through the feed system in front of the furnace to incinerate to generate heat and generate electricity. The incineration efficiency of the incinerator is directly related to the uniformity of biomass fed into the feed system before the furnace. If it is stable, the combustion will not be sufficient, not only the biomass energy cannot be fully utilized, but also more waste gas pollution will be produced. The current feeding system in front of the furnace can have normal input uniformity for clearly classified and fully crushed biomass, but the current equipment needs to fully crush the biomass, and the cost is relatively high. There are various types or disorderly, and it is not easy to fully crush when encountering biomass like straw and entanglement. Therefore, it is ...

[0002] Biomass power plants send the crushed biomass to the incinerator through the feed system in front of the furnace to incinerate to generate heat and generate electricity. The incineration efficiency of the incinerator is directly related to the uniformity of biomass fed into the feed system before the furnace. If it is stable, the combustion will not be sufficient, not only the biomass energy cannot be fully utilized, but also more waste gas pollution will be produced

The current feeding system in front of the furnace can have normal input uniformity for clearly classified and fully crushed biomass, but the current equipment needs to fully crush the biomass, and the cost is relatively high. There are various types or disorderly, and it is not easy to fully crush when encountering biomass like straw and entanglement, so it is very easy to cause uneven input and even congestion when inputting the feed system in front of the furnace, which reduces the incineration efficiency
