Embodiment Construction
[0034] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0035] A solid fuel dispenser 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. like Figure 1-Figure 8 As shown, the solid fuel distributor 100 according to the embodiment of the present invention includes a first main pipe 110 and a first cover plate 120 .
[0036] The first main pipe 110 has a material inlet 111 and a material outlet 112 , and the first main pipe 110 has a constriction section 113 , a constant section section 114 and an expansion section 115 connected in sequence. Wherein, the constriction section 113 is adjacent to the feed opening 111 , and the expansion section 115...

The invention discloses a gasifier and a feeding device thereof, a burner and a solid fuel distributor. The solid fuel distributor includes: a first main pipe, which has a feed inlet and a discharge port, and consist of a contraction segment, an equal section segment and an expansion segment that are connected in order, with the cross section area of the contraction segment decreasing along the direction from the feed inlet to the discharge port, the cross section area of the equal section segment being invariant along the direction from the feed inlet to the discharge port, and the cross section area of the expansion segment increasing along the direction from the feed inlet to the discharge port; and a first cover plate, which is arranged on the first main pipe and caps the discharge port, and is provided with a plurality of first distribution holes. The solid fuel distributor has the advantage of uniform distribution of solid fuel, can greatly reduce the investment cost and operation cost of solid fuel transportation, effectively control the flame size, strengthen the mixing and dispersion of solid fuel and an oxidant, and reduce the backmixing and short circuit circumstances ofsolid particles in the gasifier.
Description
technical field [0001] The present invention relates to a gasification furnace, and also relates to a feeding device, a burner and a solid fuel distributor of the gasification furnace. Background technique [0002] Gasification of dry powdered solid fuels such as pulverized coal has become the mainstream technology for gasification of solid fuels such as coal due to its high cold gas efficiency, fast reaction speed, and low water and oxygen consumption. As the core gasification equipment, the burner has the functions of strengthening the mixing of solid fuel and oxidant and regulating the flow direction and degree of dispersion of gas and solid during the gasification process. [0003] At present, the process burners used in gasification furnaces can be divided into two types: multi-burner scheme and single-burner scheme according to the number of burners used in a single furnace. In the multi-burner scheme, each burner has an independently monitored pulverized coal pipelin...
