Introduction to Circulating Fluidized Bed Combustion Boiler
A circulating fluidized bed combustion boiler (CFBC boiler) is an advanced combustion technology that offers high efficiency and low emissions in power generation and industrial heating. Unlike traditional coal boilers, the CFBC boiler circulates a mixture of fuel, air, and inert materials like sand or ash in a fluidized state during combustion. This system promotes thorough mixing and extended residence time of particles, leading to complete combustion of fuel at lower temperatures.
The circulating fluidized bed combustion boiler stands out for its adaptability to various fuel types, energy efficiency, and environmentally friendly operation which makes it an attractive solution for countries and regions relying heavily on coal or biomass. As environmental regulations become more stringent, industries are increasingly turning to CFBC technology for sustainable, large-scale energy production.
Unique Features of Circulating Fluidized Bed Combustion Boiler
One of the defining characteristics of a circulating fluidized bed combustion boiler is its fuel flexibility. It can burn a wide range of fuels, including coal, biomass, sludge, petroleum coke, and even industrial waste. This makes it a highly adaptable system that can be tailored to local resource availability, reducing dependency on imported fuels and optimizing operational costs.
Additionally, CFBC boilers are known for their low combustion temperature. This feature significantly reduces the formation of nitrogen oxides (NOx), a major pollutant in traditional high-temperature combustion systems. The in-bed desulfurization process, commonly achieved by adding limestone, results in sulfur dioxide (SO₂) emissions being captured directly during combustion. Consequently, circulating fluidized bed combustion boilers can achieve both low NOx and low SO₂ emissions without the need for expensive post-combustion treatment systems.
Another advantage is the high thermal efficiency and stable output of CFBC boilers. The continuous circulation of bed material ensures even heat distribution and consistent temperature control, which is critical for both power generation and industrial applications.
ZOZEN Boiler’s SHX Series: A Case Study in Mongolia
ZOZEN Boiler has been at the forefront of CFBC technology, delivering tailored solutions that meet the specific needs of diverse clients. One significant project involved providing a circulating fluidized bed combustion boiler to a local heating initiative in Mongolia. ZOZEN supplied its SHX series 7 MW coal-fired hot water boiler, designed to operate efficiently under the region’s challenging conditions.
In this project, ZOZEN Boiler designed a customized solution based on the client’s operational requirements and Mongolia’s environmental and resource characteristics. The SHX series boiler was engineered to support multiple fuel types, including coal, gangue, biomass, industrial waste, and sludge. This capability was vital due to Mongolia’s rich coal reserves and the need for flexibility in energy sourcing.
The SHX series circulating fluidized bed combustion boiler achieves low emissions. By using in-furnace desulfurization and precise air staging, the boiler maintains nitrogen oxide emissions below 100 mg/Nm³. This level of performance not only helps reduce environmental impact but also ensures compliance with increasingly strict environmental regulations.
