Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, a feeding device for a circulating fluidized bed boiler includes a concrete drainage pipe 1 at an angle of 63° to the horizontal plane. The interior of the concrete drainage pipe 1 is equipped with multiple rows of steel plate assemblies 2 for guiding materials. The adjacent steel plates A certain gap is left between the components 2 so that the steel plate components 2 can expand freely without extrusion and arching when heated.

[0034] Such as figure 1 As shown, the steel plate assembly 2 includes an inlet fixed steel plate 3 located at the entrance of the concrete drainage pipe 1, an outlet fixed steel plate 4 located at the outlet of the concrete drainage pipe 1, and a middle fixed steel plate 5 covering the position between the inlet fixed steel plate 3 and the outlet fixed steel plate 4.

[0035] Such as figure 2 a...

Abstract

The invention discloses a feeding device of a circulating fluidized bed boiler. The feeding device comprises a concrete drainage pipe with an include angle with the horizontal plane, multiple columnsof steel plate assemblies used for guiding materials are arranged in the concrete drainage pipe, a gap is reserved between the adjacent steel plate assemblies, each steel plate assembly comprises multiple middle fixed steel plates, each middle fixed steel plate comprises a main plate with the lower side face attached to the inner wall of the concrete drainage pipe, the front ends of the main plates are provided with mounting plates thinner than the main plates, the mounting plates are provided with fastening bolts penetrating the mounting plates to be fixedly connected with the concrete drainage pipe, the rear ends of the main plates are provided with covering plates with the lower side faces flush with the upper side faces of the main plates, the length of the covering plates is larger than the length of the mounting plates, the middle fixed steel plates in the steel plate assemblies are mounted in the concrete drainage pipe, the covering plates of the adjacent middle fixed steel plates are attached to the upper side faces of the other main plates, and gaps are reserved between the mounting plates and the other main plates.

Description

technical field [0001] The invention relates to a circulating fluidized bed boiler, in particular to a feeding device for a circulating fluidized bed boiler. Background technique [0002] Circulating fluidized bed boiler is the clean coal combustion technology with the highest degree of industrialization. The circulating fluidized bed boiler adopts fluidized combustion, and its main structure includes two parts: the combustion chamber and the circulating furnace. The biggest difference from the bubbling fluidized bed combustion technology is that the operating wind speed is high, which strengthens the heterogeneous reaction processes such as combustion and desulfurization, and the boiler capacity can be expanded to a large capacity acceptable to the power industry. At present, circulating fluidized bed boilers are already very good It solves basic problems such as thermal, mechanical, and material science, as well as engineering problems such as expansion, wear, and overtem...
