Example Embodiment

[0036] The specific embodiments of the present invention will be further described below in conjunction with the drawings:

[0037] The method for measuring the length of the tuyere swirling zone of a COREX melter-gasifier according to the present invention includes the following steps:

[0038] 1) Sampling; such as figure 1 As shown, on the center plane of the tuyere 2 of the COREX melter-gasifier, along the radial direction of the COREX melter-gasifier 1, from tuyere 2 to the center of the COREX melter-gasifier 1, take tuyere coke samples through tuyere samplers 3 respectively , And number the obtained tuyere coke samples;

[0039] 2) Calculate the porosity of the tuyere coke samples at different positions. The porosity of the tuyere coke samples refers to the porosity of the entire particle size;

[0040] 3) Take the distance between the sampling point and the tuyere as the abscissa and the porosity of the tuyere coke sample as the ordinate to draw a coordinate diagram;

[0041] 4)...

Abstract

The invention relates to a measuring method of length of a convolution region of an air vent of a COREX fusion gasification furnace. The method comprises following steps that 1) sampling is performed; 2) gap degrees of air vent coke samples in different positions are calculated; 3) the distance from sampling points to an air vent is taken as the abscissa and the gap degrees of air vent coke samples is taken as the ordinate to draw a coordinate graph; 4) and a catastrophe point exists in the gap degrees of air vent coke samples in the coordinate graph, and the distance between the corresponding position of the catastrophe point and the air vent is the length of the convolution region of the air vent of the COREX fusion gasification furnace. According to the invention, the length of the convolution region of the air vent of the COREX fusion gasification furnace is calculated by measuring the gap degrees of air vent coke samples, and the method is simple, feasible, accurate and reliable and can be taken as the basis for determining the furnace conditions of the COREX fusion gasification furnace.

Description

technical field [0001] The invention relates to the technical field of non-blast furnace ironmaking, in particular to a method for measuring the length of a tuyere swirl zone of a COREX melting gasifier. Background technique [0002] The blast furnace ironmaking process has many advantages unmatched by other ironmaking equipment, such as large production scale, high production efficiency, low energy consumption, long service life, good desulfurization performance and suitable for producing molten steel, so it has been used as a The main production process of ironmaking. However, blast furnace ironmaking also has many unfavorable factors, such as large investment scale, serious environmental pollution, inflexible production, etc., especially its heavy dependence on coke production; No or less coke and low CO 2 The emission-free non-blast furnace ironmaking process has been paid more and more attention, but currently only the COREX process developed by VAI is the only new te...
