circulating fluidized bed boiler combustion condition

Gas condensing circulating fluidized bed boiler combustion condition thermal efficiency can reach 108%, it is true or false? For efficiency condensing boiler fast boiler manufacturers can reach 108% this outcome, many users are skeptical. In their view, the definition for the boiler efficiency are: energy ratio of the energy efficient boilers and boiler operation when the input of all the energy that is effective boiler efficiency = energy / input. As such analysis, when efficiency is greater than 100%, would not be an effective means of energy condensing boiler has been greater than the energy input yet?

Recently, the field of ecological environment of Shanxi thorough investigation of illegal activities, promotion of eco-environmental quality of Shanxi be greatly improved, the central group held a provincial environmental inspectors rectification illegal sewage major renovation "Hundred Days cleared" special action mobilization meeting, asked the province up and down quickly action to ensure that the "Hundred Days cleared" special action to achieve tangible results.

"Clear Days" special action include 10 aspects: the central environmental protection inspectors and inspectors "looking back" clear feedback issues; national air pollution control and strengthen supervision and three cities in northern Shanxi air pollution control special inspection found problems rectification task clear; focus on the problem of sewage from polluting units cleared; "ban on coal zone" bulk coal cleared; "scattered dirt" enterprise is cleared; key areas of coal-fired boilers cleared out of the task; urban area construction site dust pollution problem is cleared ; diesel truck phenomenon of black smoke cleared; cities above the county level and type of surface water environmental violations centralized drinking water source protection areas cleared; annual key water pollution control project is completed cleared.

Clear focus: focus on examination of 624 key polluting units of pollution control facilities, operation and pollutant emissions. Implementation of the rectification May inform the Provincial Department of environment and supervise the handling of seriously overweight key sewage units - one by one to verify the fourth quarter of 2018, in 2019 the Department of Ecology and Environment informed the first quarter supervise the handling of seriously overweight key polluting units, 2019 1 situation and the implementation of administrative penalties.

Specific objectives: In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products, slashing the average concentration of sulfur dioxide in the ambient air quality.

Clear focus: the use of coal for municipalities within the scope of "no coal zone" in the home spot checks to ensure that alternative livelihood and heating coal for clean energy or clean heating methods is strictly prohibited within the store "ban on coal zone" sales and burning the behavior of coal and its products.

Clear Focus: targeted surveillance cities out of the task list of coal-fired boilers. In built-up areas to ensure that municipalities and districts out of 35 tons and coal-fired boilers, county (city) eliminated the basis of built-up area and 10 tons of coal-fired boilers on October 1, 2019, Taiyuan, Yangquan, Linfen City, Jinzhong city, four global, Luliang Fenyang, Xiaoyi, the text of water, Jiaocheng, Yuncheng salt lake, Wenxi, Xinjiang, Jishan, Hejin global phase-out of 35 tons of steam coal-fired boilers, Changzhi city completed 35 tons of steam out of the task more than 50% of the amount of coal-fired boilers, Jincheng complete 20 tons of steam coal-fired boilers eliminated within the municipal area.

Variable frequency electric circulating fluidized bed boiler combustion condition with ordinary electric boilers What difference does it make? 1. 30% -50% of the operating cost difference frequency electric boiler is lower than the operating costs of ordinary electric boilers. Run only in low power periods. Thus, under the same power consumption situation, our variable frequency electric electricity per kilowatt boiler is only the difference between 1 / 3-1 / 4.2. Other electric boiler boiler system, leading to differences in thermal efficiency and heat capacity frequency electric boiler, which boiler system generally includes a boiler, heat exchanger, circulating pump frequency electric boiler with demineralized water and means electrically common external boiler thermal storage apparatus with no need, therefore, relatively small footprint. Ordinary electric boiler, in addition equipped with variable frequency electric boiler, but also supporting a large volume holding tanks. Tank insulation insulation, heat storage effect is far less frequency electric boilers, so many users that contribute to inadequate presence during use. Difference frequency electric boiler, boiler 3. The body structure of the body structure greatly different from the conventional general electric boiler, using solid alloy material therein and integrated design, the heating, heat storage, heat removal, heat exchangers and control functions in combination together to form a variable frequency electric boilers. Due to the high-density solid material and an alloy with integrated design, the premise to achieve the same heating effect, the overall volume of the boiler is 1/10 of an ordinary electric boiler. Ordinary electric boiler general internal electric heating wire or electric heating tubes, boiler What difference does it make? No solid alloy material for heat storage. Frequency electric boiler also has a full boiler output, either heating or hot water, have to cope, it is possible to limit the large boiler system to reduce unnecessary heat loss, with environmental protection and energy saving and high security features.

Fast production side condensing gas circulating fluidized bed boiler combustion condition steam, condensed by the use of advanced technology, is provided in the vicinity of the flue condensation recovery, high temperature flue gas passes through part of the apparatus encountered latent heat of condensed water releases heat, re-absorbed by a boiler, the thermal efficiency can be 108% of the high reach. A year later, it can save companies ranging from fifty thousand to hundreds of thousands of fuel input costs (depends on the boiler capacity and maintain quality). 1 ton boiler output of 70 million kilocalories, and so, to contribute 10 tons of boiler 700 million kilocalories.

A Survey on Circulating Fluidized Bed Combustion Boilers

These boilers are termed as Circulating Fluidized Bed Combustion Boilersâ  [CFBC]. Basu and Fraser [5] have defined the CFBC boiler as follows: A circulating fluidized bed boiler is a device for generating steam by burning fossil fuels or biomass in a combustion chamber operated under special hydrodynamic condition.
