1. Adapting to a wide range of fuels. Any bituminous coal,
anthracite coal, lignite or even gangue, whose calorific value is
above ***0KJ/Kg, (***0Kcal/Kg) will be adapted. 2. Temperature of
combustion chamber is ***0 ℃ or so while its outlet temperature
is around **0 ℃. Operating temperature is uniform, and heating is
stable. 3. High combustion efficiency. Burnout rate of coal powder
is up to *5%; Thermal efficiency is more than *0%; Carbon content
in ash is less than 2%. The ashes, suitable for use as filler of
the mixture of cement and other building materials, are difficult
to coke and have a great activity, 4. Easy to ignite. The time of
banking-up is very long. Discontinuous banking-up is up to ****8
hours. And you needn’t ignite again to start after banking-up. 5.
The temperature of hot flue gas outlet is adjustable. And the
outlet of heating flue gas pipeline is convenient and flexible. 6.
Clean combustion. Owing to the low NOX content in flue gas,
desulphurization in the furnace can be achieved so that sulfur in
coal is in a solid state when entering the slag. 7. The system can
realize PLC full-automatic control and low working temperature. 8.
High temperature flue gas fluidized bed combustion furnace/boiler
enjoys a long service life. With less wearing parts, it cost low
repair expenses.
