The high temperature and sub- high pressure circulating fluidized bed boiler based on the biomass fuel mixture, developed by ZG Boiler. CFB boiler has been employed by many users.The High temperature high pressure CFB boiler is a more advanced fluidized bed boiler technology. CFB boilers have higher fluidizing air velocities ranging from 10 to 20 ft/sec.View More
Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006). Thus very little pre-treatment of the fuel is …View More
At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.View More
Absorbing domestic and foreign has been put into operation in large‐scale circulating fluidized bed boiler technology to digest, absorb successful operating experience, learn, learn from each other for high temperature and high pressure circulating fluidized bed projects to provide reliable, efficient, technical level first‐class boilerView More
The basic difference between Circulating Fluidized Bed Boiler and other boilers is combustion system. The former is composed of combustor, material collector and back-feeder. High-temperature material collector by air flow, then materials collected enters into back-feeder, through which are transported to combustor to conduct several circulating combustion.View More
R&D of a new generation of high-temperature separation circulating fluidized bed boilers Strong Technical Support Working closely with domestic and international research institutes, Zozen achieves leading global standards.View More
“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.View More
When the Å agisza power plant began commercial operation in late June 2009, it marked the beginning of a new era in the evolution of circulating fluidized bed (CFB) technology. At the heart ofView More
Usually ultra high temperature CFB boiler bed temperature control between 790V~900 ° C, the temperature of the furnace is the optimum temperature to achieve desulfurization. Not only will decrease the bed temperature is too low boiler efficiency, it will result in the boiler unstable and prone to fire.View More
The circulating fluidized bed (CFB) use high fluid velocity to provide better gas-solid contact by providing more intense mixing of the fluid so that better quality of product can be obtained. However, the high gas velocities and the recirculation of solids may make the CFB system much more expensive in term of power requirement and investmentView More
Major equipment are 2 × 280t / h high temperature and high pressure circulating fluidized bed boilers and related auxiliary components. Boiler furnace structural arrangement is reasonable to guarantee the efficient combustion. Superheater optimized system design can ensure the steam parameters.View More
The circulating fluidized bed boiler (CFB boiler) is an updated version of the BFB boiler, thus it is the second-generation fluidized bed boiler. The CFB boiler is a device that burns solid fuel to produce steam or hot water, and the boiler furnace works with special fluid dynamic characteristics.View More
