Embodiment Construction

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

[0020] In order to ensure the stability of the start-up ignition process of the transport bed gasifier, the ignition burner and the start-up burner will not be burned during the start-up process, this embodiment provides a start-up ignition method of the transport bed gasifier, the method The mid-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 at the required temperature, and then the flue gas The gas is passed into the gasifier body through the flue, so that the temperature and pressure in the gasifier body rise to the state required for feeding, so as to complete the start-up and ignition of the transport bed gasifier.

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 start-up ignition method of a gasifier and a start-up flue gas generation system, which belong to the technical field of chemical energy. Background technique [0002] Both the ignition burner and the 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 by the ignition burner, and the fuel combustion in the start-up burner generates heat. The temperature and pressure in the gasification furnace are raised to the state required by the process, and then the gasification furnace is fed into operation. [0003] During the start-up ignition process of this method, the pressure and temperature changes in the gasifier directly affect the normal operation of the start-up burner, which is prone to unstable combustion and uneven high-temperature flue gas; and the ignition burner and start-up burner It is also easy to be bur...
