Abstract

As a engineering practice of Datang Huayin lignite pyrolysis, this paper studies the recycling use of 1200 kJ/kg lignite pyrolysis by using the swirl burner based on grading fire in recirculation zone. By the method of low-calorific-value gas fuel mix burning with high-calorific-value gas fuel, this experiment successfully achieved the stable combustion of lignite pyrolysis gas, and the heating ratios of high-calorific-value gas and low-calorific-value gas can achieve 21% and 79%, maximize save energy and the high-calorific-value fuel cost.
