ZG Boiler is a professional industrial which company has coal power boiler in bangladesh manufacturer in China, ZG supplycirculating fluidized bed boiler, power plant boiler, biomass fired boiler, coal fired boiler, gas & oil fired boiler, etc. CFB boiler advantage:The most important advantage of the CFB is the flexibility of firing a wide range of coal. CFB’s can also burn a limitless number of other types of solid fuels, separately or mixed with coal.
Unlike conventional pulverized coal (PC) technology, CFBs allow for the use of lower calorie coal - 4,000 kcal/kg compared to 6,000 kcal/kg typically used in a power plant coal fuel CFB which company has coal power boiler in bangladesh - plus five percent biomass (woodchips), therefore helping reduce fuel costs and widen its procurement possibilities, without requiring add-on flue gas desulfurization equipment.
Development of CFB for power generation has been ongoing for several decades. At the end of the 1970s,First introduced CFB combustion technology originally developed for heterogeneous reactors, to the field of coal combustion. CFB operation is characterized by rapid gas–solids mixing, reactions, and heat transfer, all of which create an environment in which low-grade solid fuels can be stably burned at 800–900°C. At these relatively lower temperatures, NOxformation and emissions are much lower than what is observed for PC combustion. In addition, limestone additives can be combined in the which company has coal power boiler in bangladesh to capture the SOxin situ. Therefore, CFB offers the least expensive means to control NOxand SOxemissions from coal combustion. Other environmental benefits, such as waste reduction and a smaller carbon footprint, can also be achieved through cofiring coal with biomass or waste. As CFBs are inherently fuel flexible, they can readily accept lower rank fuels that can be varied over time pending availability and other factors.
Since 2017, Yongji County, Jilin Province to respond positively to the State Council issued the "Air Pollution Prevention Action Plan" to carry out corresponding work strictly in accordance with national, provincial and municipal environmental requirements.
It is reported that out of Yongji County vigorously promote the renovation work of small coal-fired boilers, promulgated and implemented the "little out of Yongji County boiler work program" to develop "a furnace policy" policy, no longer approve new steam 10 t / h coal-fired boiler , while promoting the phase-out of small coal-fired boilers.
For small coal-fired boiler phase-out program has been effectively implemented, Yongji County Government has formulated "Yongji County eliminate small coal-fired boiler renovation award up approach", the county built area of active users to carry out remediation work out of coal-fired boilers by small standard for financial awards complement, after the introduction of premium policy, and in the mouth before the town government to convene Yongji economic Development Zone, the area held a small coal-fired boilers user related meetings, arrangements for specific phase-out management work, and to a great extent to promote the progress of small coal-fired boilers eliminated.
Since the initial carry out small coal-fired boiler renovation work in 2017 to the present day, Yongji county built-up areas out of a total of 59 small coal-fired boiler units, a total of 16 sets of 20 tons of steam / hour non-electric and coal-fired boilers intention has been completed to upgrade pollution control facilities renovation work.
