Embodiment Construction

[0018] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0019] Generally, when the submerged combustion gasifier burner is working, it is often difficult to burn the burner due to insufficient combustion-supporting gas in the burner and long-term burning ash in the burner, which in turn affects the ignition success rate and combustion efficiency of the burner. , especially in the submerged combustion mode, the flame pressure has to overcome the water...

Abstract

The invention discloses a burner of an immersed combustion type gasifier and a combustion control system of the burner, and relates to the technical field of cryogenic liquid gasification in liquefiednatural gas and industrial gas industry. A combustion channel and an ignition channel are arranged to enable ignition and combustion to be carried out separately, the success rate of the ignition isensured. After successful ignition and flame can reach a certain intensity, the combustion operation is carried out. Through the arrangement of a butterfly valve, combustible gas in the combustion channel can be controllably entered into the combustion chamber, a small amount of combustible gas is first introduced into the combustion chamber under the condition that the early flame is not very large, and when the flame intensity is large enough, a large number of combustible gas is introduced to realize the normal combustion of the burner and ensure the combustion efficiency of the burner. Through the connection between an air fan and a combustion cavity, a large amount of air is introduced into the combustion cavity through the air fan before ignition, a large number of combustion-supporting gas can be brought to the combustion cavity while the combustion cavity is cleaned, and the ignition success rate and combustion efficiency to overcome the water pressure are further ensured.

Description

technical field [0001] The invention relates to the technical field of low-temperature liquid gasification in liquefied natural gas and industrial gas industries, in particular to a submerged combustion gasifier burner and a combustion control system thereof. Background technique [0002] When the submerged combustion gasifier burner is working, it is often difficult to burn the burner due to insufficient combustion-supporting gas in the burner and long-term burning ash in the burner, which in turn affects the ignition success rate and combustion efficiency of the burner. Especially in the submerged combustion mode, the flame pressure has to overcome the water pressure to achieve high-pressure combustion, and it is more difficult to achieve ignition and combustion under the above conditions. Contents of the invention [0003] The technical solution of the invention provides a submerged combustion type gasifier burner and its combustion control system, which solves the prob...
