Abstract

The invention discloses an igniting burner. The igniting burner comprises a burner body and an ignition device, the ignition device comprises a micro oil gun and a plasma generator which are arranged on the burner body, and flames at the ignition end of the micro oil gun and flames at the ignition end of the plasma generator are sent into the burner body. When the igniting burner is used, under the circumstance that the coal quality is excellent, the plasma generator is adopted for ignition, the ignition effect is guaranteed, and oil does not need to be burnt; under the circumstance that the coal quality is good, the micro oil gun is adopted for ignition, and the defect that the ignition fails due to the fact that the plasma generator heat is not sufficient can be made up; under the circumstance that the coal quality is poor, the plasma generator and the micro oil gun are adopted for ignition simultaneously, fuel is ignited by the adoption of a large amount of heat, so that the igniting coal quality range becomes wider, and thereby the problem that in the prior art, an igniting burner is difficult to meet igniting requirements due to the fact that the coal quality varies a lot is improved.

Description

technical field

[0001] The invention relates to the field of fuel combustion equipment, in particular to an ignition burner. Background technique

[0002] In the existing technology, the technology of plasma ignition burner and micro-oil ignition burner has been developed. Most of the thermal power plant boilers in my country have installed plasma ignition burner or micro-oil ignition burner according to the quality of coal burned. When it remains the same, the ignition is normal. However, due to changes in coal prices, most power plants will give priority to purchasing coal with high cost performance, which leads to large changes in coal quality. ignition requirements. Contents of the invention

[0003] The purpose of the present invention is to provide an ignition burner to solve the problem in the prior art that it is difficult to meet the ignition requirements of coal with different coal qualities due to the large change of coal quality in the ignition burner. [000...
