ideal sand composition of boiler cfb

An overview of how the steam-gas ideal sand composition of boiler cfb gas steam boiler: heat, water heated pot steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace is released and allowed to vaporize into steam thermal energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source.

Series ideal sand composition of boiler cfb fuel, heavy fuel oil if of course not, because pollution will be very serious, but if methanol fuel is no problem, as is eco-friendly. But the budget is not high customers, methanol fuel cost is too high, is not suitable for them.

First Affiliated Hospital of Bengbu Medical College, responsible for staff to feedback to our company, this ideal sand composition of boiler cfb to use less smoke production, in line with the special requirements of the hospital surroundings and national requirements for flue gas emissions. During the boiler installation and operation, square quick technical staff also always concerned about the dynamic boiler, parties can feel really real fast customer service, using fast boiler is assured. --customer feedback

New ideal sand composition of boiler cfb inspection work is needed by the boiler and pressure vessel safety inspection department, new boiler through its approval, supervision, and related performance tests. After testing by the boiler manufacturing unit can be formally delivered to the use of units.


in the boiler including the bed material, fuel etc.; (ii) bed material and gas in the so called Intrex, a bubbling bed below the cyclones where separated sand is fluidized and cooled in two super heaters before the sand is re-entering the CFB boiler; (iii) the steam system with water and steam.

Fluidized bed combustion - Wikipedia

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
