Metal burner for preparing methanol synthesis gas

Abstract

The invention provides a metal burner for preparing methanol synthesis gas. The side wall of a burner body is provided with a cooling water inlet and a cooling water outlet which are communicated into the burner body; the side wall of the burner body is also provided with a protection steam inlet communicated into the burner body; the inlet end of the burner body is provided with an oxygen / steam inlet; the part of the burner body, which extends into a furnace, is provided with a protection sleeve; the position at the front end of the head part of the burner body is provided with a gas distributor; and the gas distributor and the burner body are fixed by an inclined pull rib. According to the invention, unplanned shutdown of a conversion process system is effectively avoided, the metal burner can safely and reliably operate in a long period, and service life of the metal burner is prolonged.

Description

technical field [0001] The invention relates to a pure oxygen metal burner using a natural gas conversion process and a coke oven gas catalytic partial oxidation process, wherein the natural gas conversion process includes: a pure oxygen two-stage conversion process and a pure oxygen partial oxidation process. Background technique [0002] Methanol is the only chemical synthesized by gasification of coal and reforming of natural gas on a large scale except synthetic ammonia. It is an important basic product of one-carbon chemical industry and organic chemical raw material. There are many kinds of raw materials for methanol synthesis technology, such as: natural gas, coke oven gas, coal, coal bed methane, crude oil, heavy oil, tar, etc., so the gas production methods and process routes of the raw materials are also very different. [0003] The methanol conversion process using natural gas and coke oven gas as raw materials, the synthesis gas (H 2 , CO and CO 2 ) The core eq...

AI Technical Summary

Problems solved by technology

Most of the early domestic reformers used heat-resistant castables, and the burners were all made of corundum bricks. The raw material gas (natural gas or coke oven gas, etc.) and oxygen were not mixed uniformly, and the fuel medium was often partially overburned in the furnace, resulting in burnout. For corundum brick burners and refractory castables in the furnace, the enterprise often stops passively to overhaul the reformer, which brings hidden dangers to the safe production of the enterprise. long, resulting in damage to the economic benefits of the enterprise
