Circulating fluidized bed combustion technology mechanism research, has assumed the "research and test modeling and numerical simulation of large-scale circulating fluidized bed combustion system working process," nearly ten National Natural Science Foundation, the national "eight five" key project and "circulating fluidized bed gas-steam generation equipment research," national "Nine Five" project "75ton circulating fluidized bed package design," and the National Key Basic Research Development Program projects. In cooperation with Canadian institutions concerned a joint application to the Canadian International Development Agency CIDA Canadian project "Development Research burning coal combustion CFB China", made a series of achievements in scientific research, especially in the circulating fluidized bed combustion , heat transfer, desulfurization and other aspects of a deeper study, in cooperation with the United Technologies Corporation a "vortex fluidized bed combustion technology research", in cooperation with the US F & W company "a new gas-solid separation technology research." Cooperation with South Korea development of large-scale circulating fluidized bed boiler. In extensive research on the basis of the mechanism for circulating fluidized bed combustion technology with sufficient awareness, especially in the hydrodynamic characteristics of circulating fluidized bed, a circulating fluidized bed coal and special fuels (anthracite, coal, coal, raw biomass fuels, coal, petroleum coke, etc.) of the combustion characteristics of a circulating fluidized bed furnace heat transfer characteristics and tail heating surface, the control process pollutants (SO2, NOx and heavy metals) circulating fluidized bed combustion, circulating fluidized Key components such as splitters bed, feed back mechanism and external fluidized bed heat exchanger. The main fluidized bed combustion test rig owned are: cross-section of 200 × 200 high as cold circulating fluidized bed test stand 4000, cross-section of 200 × 200 high of 4000 circulating fluidized bed thermal test bench, sectional as high as 500 × 500 6000 circulating fluidized bed thermal test bench, cross-section of 350 × 350 high as 10,000 hot circulating fluidized bed test bed 1MW fluidized bed combustion test stand and vortex. In addition to research in the laboratory scale test rig performed, still 75t / h circulating fluidized bed boiler and 220t / h circulating fluidized bed boiler exhaustive testing, to obtain large flow boiler, combustion, heat transfer, pollutant Characteristics emissions.
First, in line with environmental standards, higher efficiency due to low gas other fuel gas world best coal fired boiler central luzon ash, sulfur and nitrogen than coal, burning more fully, and thus the amount of dust in the dust rarely, can greatly mitigate environmental pollution, and better meet the environmental requirements of modern production, on the other hand due to better overall environmental performance of a gas boiler, prompting the convection bank erosion bear small, good heat transfer, heat radiation and strong, low exhaust gas temperature, thermal efficiency is significantly improved, better use of effects to enhance the overall durability of the good gas boiler, prompting the two complement each other to produce the effect.
Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast world best coal fired boiler central luzon R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
Personnel and to avoid faulty gas world best coal fired boiler central luzon gas boiler prone to some fault in the use of the process in order to avoid it fails, we have to understand some of the considerations when using. When using a gas boiler, we should always carry out its care and maintenance of local failure timely maintenance and replacement, make sure it is working properly. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, and should be cleaned. Low temperature liquid phase heat carrier outlet of the furnace, for lack of heat, and the exhaust gas temperature exceeds 300 ℃, the main problem is the fouling, soot blowing should be. As low exhaust gas temperature, the main issue is burning, mainly lack of the wind. Although the pressure furnace, the blast volume is not open, the furnace temperature is low, combustion insufficient strength. We should focus on rear seal machine check furnace slag, dust, etc. whether closing the ash outlet is good, with or without cold air leakage into large. Before and after the filter differential pressure increases, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. Grate stuck. The reason is often broken or grate grate fall loose pins; coal grate has stuck to metallic inclusions; arched grate; slag filter (Eagles iron) sink tip and the grate stuck. Processing method: reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. The iron eagle sink, both sides can pull the fire door pull hook n. Grate stop turning, it may be too loose chain, and sprocket meshing well, or badly worn sprocket, and chain-linked bad; the adjustment screws on both sides to re-adjust the tension grate, if still does not work, you need to exchange sprocket.
