Double fluidized bed decoupling combustion and fluidized bed two-stage gasification technology are suitable for high water content fuel, including various light industrial processes, waste and
lignite. According to different existing combustion equipment, the principle of two technologies selection is as follows:
Double fluidized bed decoupling combustiontechnology
It is mainly for steam as a heat source or power generation of new projects, such system has high level of integration, simple route and high efficiency.
Two-stage gasification of fluidized bed + gas firedboiler
It is mainly for enterprises that have gas-fired boilers, two-stage gasification of fluidized bed manufactures low tar gas, it mixes with natural gas in gas-fired boilers for mixing combustion, it can replace some natural gas, meanwhile, NOx emissions can be decreased by re-combustion.
Two-stage gasification of fluidized bed + large thermoelectricequipment
It combines with large thermoelectric boiler, we will make full use of its high energy efficiency and improve overall efficiency. Two-stage gasification of fluidized bed manufactures low tar gas, it is put into large thermoelectric boilers as re-burning fuel at high temperature, on the one hand, it can burn with boiler fuel, on the other hand, NOx could be produced by reductive combustion, nitrogen oxides emissions can be effectively decreased in flue gas.
