Embodiment Construction

[0019] The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] In order to ensure the stable starting and ignition process of the conveying bed gasifier, the ignition burner and the starting burner will not be burnt during the start of the furnace, this embodiment provides a starting ignition method of the conveying bed gasifier. The middle start burner and ignition are not directly fixed on the gasifier body, but are set on the start-up flue gas generation system connected to the gasifier body. The start-up flue gas generation system generates flue gas with the required temperature, and then the smoke The gas passes into the gasifier body through the flue, so that the temperature and pressure in the gasifier body rise to the state required for feeding, thereby completing the ignition of the transport bed gasifier.

[0021] The structure of the start-up smoke generation system used in this method is as follows figure 1 As sh...

Abstract

The invention discloses a working ignition method of a gasification furnace and a working glue gas generation system, and belongs to the technical field of chemical energy resources. The working ignition method comprises the following steps: fixedly arranging a burner for working ignition of the gasification furnace on the flue gas generation system outside the gasification furnace, and generating high-temperature flue gas used for working ignition of the gasification furnace through the flue gas generation system; then, conveying the generated high-temperature flue gas to the gasification furnace through a pipeline so as to achieve working ignition of the gasification furnace. The flue gas generation system comprises a flue gas furnace, a flue gas temperature adjusting device used for adjusting the flue gas temperature, a flame detector used for detecting whether a flame is existent in the flue gas furnace or not, a flue used for conveying flue gas, and a fire watching device. The flue gas generation system can provide the flue gas with proper temperature for the gasification furnace, so that the gasification furnace can be stably heated and the heat utilization efficiency of the gasification furnace can reach more than 99%.

Description

Technical field [0001] The invention relates to a gasification furnace start-up ignition method and a start-up smoke generation system, belonging to the technical field of chemical energy. Background technique [0002] The ignition burner and start-up burner of the existing gasification furnace are directly attached to the gasifier body. During the start-up ignition process, the start-up burner is ignited through the ignition burner, and the fuel in the start-up burner generates heat. The temperature and pressure in the gasifier are raised to the state required by the process, and then the gasifier is put into operation. [0003] During the ignition process of this method, the pressure and temperature changes in the gasifier directly affect the normal operation of the starting burner, which is prone to unstable combustion and uneven high-temperature flue gas; and the ignition burner and the starting burner It is also easily burned. Summary of the invention [0004] In view of this...
