Problems solved by technology

When there are more transfer links in the feeding system, there will be more frequent accidents such as fuel entanglement, material blockage, and uneven feeding, which will lead to the unit not being able to run stably for a long time

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0026] Such as figure 1 and figure 2 Shown: a biomass power plant without a furnace front silo feeding device, without a furnace front silo, mainly including a distributor 1, a screw feeder 2, a distributor 1 and a screw feeder 2 The blanking tube 3. The feeding belt is used for direct blanking. One feeding belt corresponds to one distributor 1, one distributor 1 corresponds to two screw feeders 2, and four screw feeders 2 correspond to the four feeders of the boiler. Material mouth. The fuel is transported to the front of the furnace by the two feeding belts, and directly falls into the two distributors 1, and then directly falls into the fourth through the blanking pipe 3 between the discharge ports of the distributor 1 and the screw feeding device 2. A screw feeding device 2 enters each feeding port of the boiler from the screw feeding device 2 respectiv...

Abstract

The invention relates to a furnace-free front storage bin feeding device for a biomass power plant. The blanking is directly performed by employing a charging belt, a charging belt corresponds to a distributor, a distributor is provided with two discharge openings; the discharge openings of each distributor are butted with a spiral feeding device through a blanking pipe; and four spiral feeding devices respectively corresponds to four feeding holes of a corresponding boiler. The device is easy, convenient and high in adaptability, the transfer link is reduced, the failure rate of the system is reduced, the height of the charging belt is reduced, the bridging and bulking phenomena in the traditional stokehole storage bin are avoided, the floor area is saved, and the cost is saved; and meanwhile, the device has good practical using effect of various biomass fuels, the stability, reliability and the safety of equipment operation in a feeding system are improved, and the device can be widely applied to various boilers for biomass power generation, and are particularly applied to circulating fluidized bed boilers.

Description

Technical field [0001] The invention relates to a feeding system of a biomass power plant, in particular to a feeder in front of a boiler of a biomass power plant. Background technique [0002] Biomass power generation technology is a key renewable energy project developed and constructed in my country in recent years. There are many varieties of biomass resources, including crop straws, rice husks, forestry wastes, crop seed shells, etc. The development of biomass power plants is energy-saving, emission reduction, and resource integration. Utilization, construction of a new socialist countryside and adjustment of power supply structure have made important contributions. [0003] At present, most of the design of the CFB boiler feed system in the biomass power generation technology is equipped with a pre-furnace silo. The silo can be large or small. Under the silo, a primary or secondary screw conveyor is arranged, and then the screw conveyor is used. Deliver fuel to the furnace fo...
