Abstract

The invention provides a burner, an entrained-flow gasifier and a combustion method of the entrained-flow gasifier. The burner comprises a first pipe body, a second pipe body, a third pipe body, a fourth pipe body and a fifth pipe body. A first gasifying agent channel is formed in the first pipe body; the second pipe body sleeves the outer side of the first pipe body; a pulverized coal channel is formed between the second pipe body and the first pipe body; the third pipe body sleeves the outer side of the second pipe body; a fuel channel is formed between the third pipe body and the second pipe body; the fourth pipe body sleeves the outer side of the third pipe body; a second gasifying agent channel is formed between the fourth pipe body and the third pipe body; the fifth pipe body sleeves the outer side of the fourth pipe body; and a cooling liquid channel is formed between the fifth pipe body and the fourth pipe body. The burner can finish ignition, work starting and coal feeding functions, so that a combustion process is simplified, and the burning efficiency is improved; and two gasifying agent channels are formed, so that pulverized coals and a gasifying agent are mixed twice, the mixing effect of the pulverized coals and the gasifying agent is improved, and the improvement of the carbon conversion efficiency of the pulverized coals is facilitated.

Description

technical field [0001] The invention relates to combustion technology, in particular to a burner, an entrained-bed gasifier and a combustion method for the entrained-bed gasifier. Background technique [0002] In the entrained bed gasifier equipment, the burner is one of the important components, which is used to complete the functions of ignition, start-up and coal feeding. [0003] In the prior art, the burner of the entrained bed gasifier includes three independent burners: an ignition burner, a start-up burner and a coal feeding burner, and these three burners respectively complete the functions of ignition, starting operation and coal feeding. First, the ignition burner is responsible for igniting the fuel, and then the start-up burner continues to inject fuel into the furnace of the entrained bed gasifier. The fuel continues to burn in the furnace to generate heat, so that the temperature in the furnace continues to rise. When the temperature reaches the coal feeding ...
