To address the challenges of poor simulation accuracy, low utilization of raw coke oven gas, and insufficient parameter monitoring in experimental coke ovens, an improved design was proposed based on TRIZ theory. By optimizing the coking chamber material and heat transfer structure, the system’s durability was enhanced. An integrated purification system was designed, achieving a tar condensation recovery rate of 92% and removal efficiencies of H2S and NH3 exceeding 95%, thereby fulfilling dual objectives of resource recovery and environmental sustainability. Pressure and gravity sensors were incorporated for real-time coke expansion and weight loss monitoring. After optimizing the coal blending formulation, the hydrogen yield was increased by 15%~20%. Post-improvement verification demonstrated a 25% reduction in validation costs and a 30% shortening of the R&D cycle, establishing a high-precision platform for low-carbon transformation in the coking industry. The efficacy of TRIZ theory in driving innovation in industrial equipment was validated.
