coal fired boiler for concrete pole factory

75ton h CFB coal fired boiler for concrete pole factory

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.

AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam coal fired boiler for concrete pole factory fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.

Our case with 10-ton coal fired boiler for concrete pole factory. Operating costs 10 tons of coal-fired boilers coal 600 yuan / ton, compared with 0.6 yuan / kg; calorific value 5500 kcal / kg; required heat 6 million kcal / hour and 10 ton boiler; coal boiler thermal efficiency 70-80 % (75% in accordance with our calculated): 10 tons of coal fired boiler 1 hour the desired amount: 6000000kcal / h ÷ 5500kcal ÷ 75% = 1455kg / h; 10 tons of coal boiler 1 hour investment costs: 1455 × 0.6 = about 873 yuan. 10 tons of gas boiler running costs of piped natural gas price of about 2.8 yuan / Nm3; calorific value of 8600 kcal / Nm3; thermal efficiency between 90% -95% (we calculated 90%); caloric needs 6 million is 10 ton boiler cards / hour, i.e. 77.52Nm3 / h; 10 tons of gas required for the gas boiler 1 hour: 6000000kcal / h ÷ 8600kcal ÷ 90% = 775.2Nm3 / h; 10 tons of gas boiler 1 hour run investment costs: 2.8 yuan / Nm3 × 775Nm3 / h = 2170 dollars.

Most people will choose to coal fired boiler for concrete pole factory "from coal to gas," This is mainly because natural gas has the advantage of this type of energy significant environmental characteristics and higher clean energy. However, the road from coal to gas boiler was not always smooth, many users are using coal-fired boilers, the face of high "coal to gas" and post-investment costs are very hesitant.
