How can ZOZEN Boiler enhance combustion efficiency and emissions control in a circulating fluidized bed coal fired power plant?

05 Sep 2025

ZOZEN Boiler delivers a comprehensive solution to raise efficiency and reduce emissions in a circulating fluidized bed coal fired power plant by combining robust engineering, advanced fluidization design, and smart control systems.

First, ZOZEN’s CFB technology optimizes the air–fuel–solid interaction through carefully designed furnace geometry, high-efficiency separators, and staged combustion, enabling long residence time and uniform temperature distribution. This uniformity is central to stable combustion and high burnout rates across diverse coal qualities, biomass blends, and even low-calorific fuels—flexibility that is critical for a circulating fluidized bed coal fired power plant operating under varying fuel markets.
Second, ZOZEN Boiler integrates in-furnace desulfurization with limestone injection, capturing SO2 directly in the bed and minimizing backend load. NOx is inherently low due to the moderate combustion temperature and staged air supply; ZOZEN further refines this with precise oxygen control and optimized secondary/tertiary air distribution.

Third, the company’s high-efficiency cyclones and loop seals maintain strong solids circulation, improving heat transfer and stabilizing the bed, while wear-resistant linings and high-grade alloy materials extend component life. On the thermal side, ZOZEN designs economizers, air preheaters, and superheater reheater arrangements to raise overall plant efficiency and achieve targeted steam parameters for power generation.

Digital control is another advantage: ZOZEN’s DCS/PLC strategies, with online monitoring of bed temperature, differential pressure, and oxygen, keep a circulating fluidized bed coal fired power plant operating at its optimal point, reducing unburned carbon and auxiliary power consumption. The result is consistent, low-emission performance that aligns with stringent standards.

ZOZEN Boiler backs this with turnkey services—site assessment, fuel testing, CFD simulation, BOP coordination, commissioning, and operator training—ensuring a faster ramp-up and sustained reliability. Lifecycle support includes predictive maintenance, spare parts management, and performance tuning as fuels or dispatch profiles change. Whether greenfield or retrofit, ZOZEN tailors pressure parts and balance-of-plant interfaces to existing layouts, shortening outages. For owners seeking high availability, fuel flexibility, and lower LCOE, ZOZEN’s CFB portfolio is a proven path to superior combustion efficiency and emissions control in a circulating fluidized bed coal fired power plant.
