Abstract

The invention discloses an unpowered layered and lined coal feeding device of a chain grate boiler. The unpowered layered and lined coal feeding device comprises a layered grating, lined baffles and fixing and adjusting mechanisms thereof, wherein the layered grating is divided into a dense rod area, a sparse rod area and a rodless area from top to bottom; the lined baffles are arranged under the dense rod area of the layered grating; the layered grating is obliquely arranged and has a low front part and a high rear part; the lined baffles are obliquely arranged and has a high front part and a low rear part; the layered grating and the lined baffles are respectively provided with the adjusting mechanism with an adjustable oblique angle; and the layered grating and the lined baffles are arranged between the front end of a grate of the boiler and an outlet of a coal bin, and are respectively provided with a fixing mechanism with an adjustable installing height. The unpowered layered and lined coal feeding device has the advantages that external power and a transmission mechanism are not needed, the structure is simple, the operation and the adjustment are simple and convenient, the fault rate and the maintenance cost are low, the adaptability of the boiler to the quality, the water content and the granularity of coal are improved, the burning efficiency is high, the energy consumption is low, the safety of the coal bin of the boiler is improved and the coal resource is greatly saved.

Description

technical field [0001] The invention relates to a non-powered layered and branched coal feeding device for a chain grate boiler, which is used for layered and branched coal feeding of the chain grate boiler. Background technique [0002] At present, the layered branch coal feeding device for chain grate boilers on the market requires additional power and its transmission system, which increases the power consumption of the system. The adaptability to moisture changes is poor, and the operation and adjustment are time-consuming and laborious, which affects the thermal efficiency and safety of the boiler. Contents of the invention [0003] The invention provides a non-powered layered branch coal feeding device for chain grate boilers, which does not require additional power and transmission systems, has a simple structure, low production, maintenance and operation costs, has strong adaptability to changes in coal types and raw coal moisture, and can be adjusted in operation....
