Description
Summary:Given that coal may be oxidized and the yield of ammonia and hydrogen sulfide cannot be predicted from the volatile matters, mathematical formulas describing the yield of the basic coking products as a function of the elemental composition of the initial stamped coal batch are derived. It is found that, with increase in the content of gas coal (and hence in the volatile matter) in the stamped batch, the coke yield declines, but there is a higher yield of tar, benzene, carbon dioxide, pyrogenetic moisture, and coke-oven gas. The yield of the basic coking products is found to be additive. Hence, the total yield for the enterprise may be calculated, taking account of the characteristics and proportions of stamped and unstamped batch.
