Partial oxidation process burner and application thereof

Abstract

The invention discloses a partial oxidation process burner and application thereof. The burner mainly comprises a gasifying agent channel, an auxiliary gasifying agent channel, a fuel channel and a protecting fuel channel which are sequentially arranged from inside to outside. The partial oxidation process burner is applied to a gaseous hydrocarbon converting furnace and is capable of protecting the end surface of a nozzle from being flushed and etched by high-temperature synthesis gas, flame of the burner is low in temperature and uniformly distributed, and high-temperature flame is far from the end surface of the burner, so that temperature of the end surface of the nozzle is remarkably decreased, the burner can be protected without cooling water, and meanwhile, the temperature of a burner flange is low. The partial oxidation process burner has the advantages of being simple in structure, long in service life, wide in application range and the like and has very wide application prospect.

Description

technical field [0001] The invention relates to a partial oxidation process burner and its application. Background technique [0002] Natural gas, shale gas, coal bed methane, oilfield gas, refinery gas, coke oven gas, pyrolysis gas and other gaseous hydrocarbons, with methane as the main component, are important basic energy and chemical raw materials. The conversion of gaseous hydrocarbons to synthesis gas is one of the important technical routes for the utilization of these gaseous hydrocarbons. Among them, the non-catalytic partial conversion technology of gaseous hydrocarbons has been paid more and more attention by the industry. [0003] The non-catalytic partial conversion process of gaseous hydrocarbons refers to the process of gaseous hydrocarbons and gasification agents (such as steam, carbon dioxide, oxygen, etc.) The combustion reaction provides heat for the reforming process; the reforming reaction occurs in the recirculation zone and the lower part of the ref...

Problems solved by technology

[0006] In view of the above existing reformer burner problems such as easy ablation and short service life, the present invention provides a new reformer burner design

The present invention controls the temperature field near the burner through the design of the burner flow channel, by setting the auxiliary gasification channel so that the oxidant does not directly contact with the fuel entering the furnace at the nozzle end; by setting the protection fuel gas channel so that the oxidant does not contact the furnace The high-temperature syngas recirculated inside is in direct contact with the end of the nozzle, and at the same time, it solves the problem that the high-temperature syngas enters the gap between the burner and the refractory brick of the burner cylinder, which may cause overheating of the burner installation flange

The burner of the reformer provided by the present invention can solve the problem of burner ablation without burner cooling water, without the problems of emergency shutdown of the system and damage to the refractory bricks in the furnace caused by the operation failure of the burner cooling water system, which greatly improves The operating cycle of the reformer
