Abstract

The invention discloses a high-temperature combustion-supporting device and a backfire biomass fuel dedicated combustion device. The high-temperature combustion-supporting device comprises a ring-shaped body. The inner surface of the ring-shaped body is inverted-cone-shaped or inverted-regular-pyramid-shaped, the outer circumferential surface thereof matches the inner shell shape of the combustion device. The ring-shaped body has integrated structure or combined structure. The dedicated combustion device comprises an inner shell, a water jacket and an outer shell. An upper grate and a lower grate are arranged inside the inner shell. A feed port and a high-temperature fume outlet penetrate the inner shell, the water jacket and the outer shell. An ash outlet is formed at the lower part of the inner shell. The high-temperature combustion-supporting device is arranged on the inner shell wall below the upper grate. A dedusting shroud is arranged on the inner shell relative to the high-temperature fume outlet. A dedusting mesh is arranged at the lower port of the dedusting shroud. A secondary air inlet penetrates the inner shell, the water jacket and the outer shell. The high-temperature combustion-supporting device and the backfire biomass fuel dedicated combustion device have the advantages of reasonable design, complete combustion, suitability for various fuels and good social and economic benefits.

Description

1. Technical field: [0001] The invention relates to a combustion device, in particular to a high-temperature combustion supporter and a special combustion device for backfired biomass fuel. 2. Background technology: [0002] Biomass fuel is a fuel that is directly used by compression molding of crop straw, wood chips, sawdust, peanut shells, corn cobs, rice husks, branches, leaves, and hay. Without any additives and binders. It is a renewable clean energy. According to the requirements of the "Renewable Energy Law" of the People's Republic of China, the National Development and Reform Commission organized the compilation of the "Renewable Energy Medium and Long-Term Development Plan" in August 2006, and proposed the development goals and tasks of renewable energy from 2010 to 2020. , Biomass solid briquette fuel reached 1 million tons and 50 million tons respectively, and established the status of biomass solid briquette fuel as a modern clean energy. [0003] At present,...
