Abstract

The invention discloses a yellow haulm feeding system of a biomass energy power plant and a coordinating and controlling method thereof. A sub-packaging platform is connected with an inlet of a haulm crusher by a chain scraper conveyor at one side of the sub-packaging platform and a chain scraper conveyor at one side of the haulm crusher; an outlet of the haulm crusher is connected with a stokehole storage bin distributor by a belt conveyor with a large inclination-angle and wavy retaining sides; a boiler feeding screw conveyor communicated with a boiler cavity is connected with the stokehole storage bin distributor, wherein, the sub-packaging platform, the chain scraper conveyor at one side of the sub-packaging platform, the chain scraper conveyor at one side of the haulm crusher, the haulm crusher, the stokehole storage bin distributor and the boiler feeding screw conveyor are all of two sets and all connected with the belt conveyor with the large inclination-angle and wavy retaining sides after each set is coordinately connected together. The invention is provided with two sets of mutually auxiliary systems, coordinates and controls the starting and stopping in sequence, automatic regulating, and linking and protecting functions of the feeding system and can ensure that the boilers of the biomass energy power plant run stably and meets the needs of electrical load change.

Description

technical field [0001] The invention relates to a material feeding system and a control method thereof, in particular to a material feeding system of yellow straw in a biomass power plant and a coordinated control method thereof. technical background [0002] Straw power plants are collectively referred to as biomass power plants. The fuel required for boiler combustion is various plant wastes such as rice stalks, wheat stalks, cotton stalks, corn stalks, rape stalks, peanut shells, bark, branches, corncobs, wood chips, etc., among which rice stalks , wheat stalks are called yellow stalks, and the rest are called gray stalks. [0003] The control of the feeding system of the biomass power plant is a comprehensive and continuous monitoring method for straw bag feeding, crushing, bulk material conveying, lifting, and feeding, which is used to ensure the stable power generation of the power plant. [0004] In a biomass power plant, the material delivery system from the materia...
