Abstract

The invention relates to an Undok pulverized coal gasification furnace, and particularly relates to an Undok pulverized coal gasification furnace with a steam pressurizing device for solving the problems that in the running process of an existing Undok pulverized coal gasification furnace, carbon content in combustible materials in fly ash is 20%-80%, resulting in high specific coal consumption and low carbon conversion rate of the coal gasification furnace. A cyclone separator is communicated with the gasification furnace through an inlet of the cyclone separator, two ends of a discharging channel are respectively communicated with the cyclone separator and the gasification furnace, a steam pipeline is arranged on the discharging channel, a steam nozzle is arranged in the discharging channel and installed on the steam pipeline, a spout of the steam nozzle faces an outlet of the discharging channel, a steam flow regulating valve is installed on the steam pipeline, and a descending channel pressure measuring point is arranged between the steam nozzle and the outlet of the discharging channel and installed on the discharging channel. The Undok pulverized coal gasification furnace provided by the invention is used for producing feed gas through chemical synthesis and fuel oil synthesis, industrial fuel gas, domestic gas, metallurgical reducing gas, fuel gas for combined cycle power generation, and the like.

Description

technical field [0001] The invention relates to an Ende pulverized coal gasifier, in particular to an Ende pulverized coal gasifier with a steam booster. Background technique [0002] According to China's energy policy and the current situation of my country's energy resources that are poor in oil, less in gas and more in coal, coal will be the main primary energy for a long period of time. In the case of my country's coal-based energy consumption structure, the use of gasification, a clean technology, is an effective means to improve coal utilization efficiency, reduce pollution and realize comprehensive energy utilization. Coal gasification technology is widely used in the following fields: raw material gas for chemical synthesis and fuel oil synthesis, industrial gas, civil gas, metallurgical reduction gas, combined cycle power generation gas, etc. [0003] The invention is aimed at the Ende pulverized coal gasifier. The main equipment of the gasifier is composed of coa...
