Coal fuel size in CFBC coal fired horizontal boiler

CFBC uses crushed coal of 3 to 6 mm size.This requires only a crusher not a pulverizer.From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace. Start up is by oil burners in the furnace.Ash spouts in the furnace remove the ash from the bottom of the furnace.

Our case with 10-ton coal fired horizontal boiler. 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.

18-20 May 2017, ISH heating HVAC industry event successfully held in Beijing International Exhibition Center. Fast coal fired horizontal boiler latest on-line premix vacuum hot water boiler landmark "Thalia T6" and coupled steam boiler, "Euromonitor θ5" series of products also opened a mysterious veil, show it to all visitors.

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 coal fired horizontal boiler 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.
