Abstract

The invention discloses a pressurization and ignition device and method. The ignition device comprises a burner, a rectification furnace and a reaction furnace. The burner is connected with the rectification furnace through a flange. The rectification furnace is connected with the reaction furnace through a tee joint. The rectification furnace is provided with an annular air distribution pipe. The reaction furnace is internally filled with solid particles in advance. According to the pressurization and ignition device and method, on one hand, a certain pressure and solid material cycle is established for a system, and the phenomena of fluctuation of system parameters and nonuniform temperature distribution of the reaction furnace are avoided; and on the other hand, by calibrating action of an adjustment valve, the purpose of precisely controlling the mixing ratio of natural gas to air required in the ignition process is achieved, ignition efficiency is improved, and meanwhile, by means of the tee joint, excessive combustible gas can be prevented from entering the rectification furnace and the reaction furnace.

Description

technical field [0001] The invention relates to an ignition device and a method for pressurized circulating fluidized bed coal gasification and coal pyrolysis technology before feeding and operation, in particular to a pressurized ignition device and method. Background technique [0002] Coal is cheap energy and the lowest cost energy in the process of supporting economic development. At present, coal consumption accounts for more than 65% of primary energy consumption in my country. The supply of primary energy will always be dominated by coal in the short term. However, the utilization of coal The process seriously pollutes the environment and the energy utilization rate is low. To this end, my country will have to actively promote the innovation and development of coal clean utilization technology. On June 1, 2016, the National Development and Reform Commission and the National Energy Administration announced the "Energy Technology Revolution Innovation Action Plan (2016-...
