Case introduction
Shanxi China Resources Coal Industry Co., Ltd., with an annual production capacity exceeding 10 million tons, serves as a benchmark in regional coal supply and clean transformation. Operating in high-altitude and multi-site scenarios, the company places high demands on the stability of its energy systems and environmental compliance.
Industry Challenges:
Coal washing and drying processes are highly time-sensitive, with frequent starts and stops, leading to unstable steam pressure.
High altitude and low oxygen levels can reduce the efficiency of conventional burners and disrupt emission control.
Strict NOx emission standards and gas consumption per unit of steam directly impact operational costs.
The YUYAN Boiler WNS Series 10 t/h gas-fired steam boiler, equipped with a condenser, economizer, and low-nitrogen burner, maximizes waste heat recovery from flue gas. It utilizes the latent heat released from water vapor condensation in the flue gas to preheat boiler feedwater, reducing exhaust temperature and gas consumption. The boiler ensures stable steam output with ample emission margins. Its large-capacity furnace and sufficient steam storage space enable smoother operation, while the optimized heating surface layout delivers higher thermal efficiency and superior steam quality.
Customer feedback
As a coking enterprise, we have strict requirements for steam quality, environmental standards, and project timelines. The YUYAN Boiler WNS 10-ton gas-fired boiler demonstrated reliable performance in high-altitude commissioning and low-nitrogen control. The shop-assembled design allowed us to complete the renovation within a short period. Additionally, the waste heat recovery system, incorporating condensers and economizers, has led to a tangible reduction in gas consumption.
