RESEARCH OF HEATING SURFACES FOR SLAG DESCENT FROM HEATING WELLS USING HYDROGEN-CONTAINING (COKE) GAS

Abstract

An analysis of the known researches on the burning characteristics of hydrogen-containing mixtures was carried out, with the determination of the flame propagation speed of the mixtures, in particular coke gas, which contains 50–60 % hydrogen. The optimal angle φ = 26 ± 1° of the meeting of the torch and the inner concave surface of the chute of the structure existing at the enterprise was experimentally determined, which ensures the necessary layering of the torch. Thanks to the organization of the prepared mixture of fuel gas and air in the burner and the creation of two streams of burning gases with different orientations in relation to the individual surfaces of the unit for the descent of slags, the task of their high-quality heating and reliable draining of slags has been solved. Using the example of coke gas, the possibility of reliable combustion of a gas mixture with an amount of hydrogen in its composition of 50–60 % was confirmed when organizing a prepared (homogeneous) mixture with air. The optimal parameters of the reliable operation of the burner for burning coke gas were determined and it was shown that the operation of the experimental coke gas burner within its control characteristics is satisfactory.
