Solid waste and biomass fuel incineration technique has become one hot-spot of study for sustainable development. All conventional combustion techniques are with dry bottom furnace

and hence the boiler efficiency is lower due to the ash fusion point of solid waste and biomass fuel is generally low

the combustion temperature being limited. For this

a solid waste and biomass fuel swirling combustion technique with slag-tap furnace has been put forward

making the fuel to be easily ignited

and the combustion temperature to be very high

enhancing the economic efficiency and reliability of boiler operation.
