Covering capacities from 260 t/h to 1,000 t/h, it combines advanced combustion technology, high thermal efficiency, and outstanding fuel flexibility. The boiler achieves over 95% in-furnace desulfurization efficiency and more than 92% thermal efficiency while maintaining low NOx emissions through low-temperature combustion. Engineered for long-term reliability, environmental compliance, and stable operation, it supports a wide range of fuel qualities and provides an economical, sustainable solution for large-scale power generation and cogeneration applications.
The Large-Scale CFB Power Station Boiler from Taiyuan Boiler Group represents the flagship of our circulating fluidized bed power generation portfolio, covering capacities from 260 t/h to 1,000 t/h. This large-scale CFB power station boiler is engineered for major utility power plants and large industrial captive power facilities that demand maximum reliability, fuel flexibility, and environmental compliance.
As a mature CFB power station boiler platform, the large-scale CFB leverages decades of circulating fluidized bed research to deliver stable steam output across a wide range of coal qualities and operating conditions. The large-scale CFB power station boiler integrates advanced combustion, heat transfer, and emission control technologies into a single optimized system, making it the preferred circulating fluidized bed solution for large-scale baseload power generation projects worldwide. Each large-scale CFB unit is tailored to site-specific fuel characteristics, grid requirements, and environmental regulations, ensuring the CFB power station boiler achieves its full performance potential throughout its operational lifetime.
The design philosophy of the large-scale CFB power station boiler centers on scalability, reliability, and emission pre-control rather than end-of-pipe treatment. Every large-scale CFB is configured with a balanced combination of furnace height, cross-sectional area, and cyclone separation efficiency to maintain uniform circulating fluidized bed hydrodynamics at all load levels. The CFB power station boiler design team uses computational fluid dynamics and thermal modeling to optimize gas-solid mixing, residence time distribution, and heat absorption profiles within the large-scale CFB furnace. This rigorous design approach ensures that the circulating fluidized bed combustion zone operates within the ideal temperature window for simultaneous combustion efficiency and pollutant suppression. The large-scale CFB power station boiler also incorporates redundant safety margins in pressure parts, support structures, and refractory systems to achieve design lifetimes exceeding 30 years under demanding baseload conditions.
The large-scale CFB power station boiler incorporates Taiyuan Boiler Group's proprietary third-generation circulating fluidized bed combustion technology, achieving in-furnace desulfurization efficiency above 95% and in-furnace SNCR denitrification efficiency above 60%. This CFB power station boiler eliminates the need for separate wet flue gas desulfurization towers and selective catalytic reduction systems, significantly reducing both capital investment and operating expenses. The large-scale CFB features a water-cooled wind chamber, membrane wall construction, and high-efficiency cyclone separators that ensure uniform flow fields throughout the CFB power station boiler furnace. Combustion efficiency reaches 95% with fly ash carbon content below 2%, while thermal efficiency of the large-scale CFB power station boiler can exceed 92%. The circulating fluidized bed combustion process operates at 850 to 950 degrees Celsius, which inherently suppresses thermal NOx formation and enables efficient sulfur capture within the large-scale CFB system.
Operating a large-scale CFB power station boiler delivers measurable economic and environmental advantages over conventional pulverized coal alternatives. The circulating fluidized bed technology allows the large-scale CFB to accept lower-grade fuels that would be unsuitable for traditional boilers, reducing fuel procurement costs while maintaining stable CFB power station boiler output. The large-scale CFB achieves load-following capability down to 50% of rated capacity without auxiliary fuel support, providing grid stability services while preserving emission compliance. Maintenance intervals for the CFB power station boiler are extended by the low combustion temperature, which reduces ash slagging and high-temperature corrosion on pressure parts. The large-scale CFB also produces less bottom ash and more fly ash suitable for cement production, transforming the CFB power station boiler into a valuable contributor to the circular economy.
Taiyuan Boiler Group provides comprehensive installation and commissioning support for every large-scale CFB power station boiler project, ensuring smooth transition from construction to commercial operation. The large-scale CFB is delivered with detailed erection drawings, lifting plans, and welding procedures prepared by experienced circulating fluidized bed specialists. Field assembly of the CFB power station boiler follows a sequenced module approach that minimizes critical path duration and reduces site labor requirements. During commissioning, the large-scale CFB undergoes cold circulating fluidized bed tests, fuel ignition trials, load ramp verification, and emission guarantee tests under varying operating conditions. The CFB power station boiler commissioning team trains local operators on control logic, emergency procedures, and routine maintenance, enabling the large-scale CFB to achieve reliable performance from the first day of operation.
The large-scale CFB power station boiler is ideally suited for 50 MW to 150 MW utility power plant units, large-scale captive power plants in the chemical and metallurgical industries, regional combined heat and power cogeneration projects, and industrial park integrated energy supply systems. The CFB power station boiler has been successfully deployed in over 50 units across Inner Mongolia, Xinjiang, Shanxi, and other regions, serving as reliable circulating fluidized bed power generation solutions for major thermal power projects. Each large-scale CFB power station boiler installation has demonstrated exceptional reliability with availability factors exceeding 95%. The circulating fluidized bed technology has proven its capability to handle variable fuel qualities while maintaining consistent steam output and emission compliance, establishing the large-scale CFB power station boiler as the trusted choice for utility-scale power generation applications.
Every large-scale CFB power station boiler is designed, manufactured, and tested in strict accordance with national and international standards. The CFB power station boiler complies with GB/T 10180 boiler performance test codes, GB 13223 emission standards for thermal power plants, ASME Section I and VIII requirements, and ISO 9001 quality management protocols. The large-scale CFB pressure parts are fabricated under ASME "S" and "U" stamp authorization, while the circulating fluidized bed design undergoes independent third-party verification. The CFB power station boiler also meets rigorous local environmental permits for SO2, NOx, particulate matter, and mercury emissions. Through this comprehensive compliance framework, the large-scale CFB power station boiler provides clients with confidence that their circulating fluidized bed investment meets all regulatory and technical requirements.
