Optimal heating system organization in coke ovens

Аннотация

In optimizing the organization of the coke oven’s heating system, the feasible region of parameter values is identified and analyzed. Previous research has shown that optimal organization of the heating system calls for the forced recirculation of gas fluxes with recirculation rates exceeding those currently employed and also for measures that simultaneously permit energy conservation and curb nitrogen oxide emissions. To that end, the influence of recirculation on process parameters is analyzed in the present work, and the feasible region is found on the basis of the following constraints: no reduction of heat supplied for the coking process; and unchanged consumption of coke-oven gas. In addition, the basic parameters of the power generation subsystem are determined by assessing the energy balance.
