Considerable interest was focused on multi-flame-retardant composite for polycarbonate since relatively small amount can significantly improve flame retardancy.

Due to the complicated,high moisture content and low calorific value of MSW as well as poor thermal stability by direct incineration,combustible solid compound fuels were prepared using orthogonal ingredients of which were comprised of MSW,municipal sludge and appropriate amount of auxiliary components.

The results showed that CCCI combustion process comprised HCCI combustion and pre-mixing combustion,diffusion combustion.

It is pointed out that the type of boiler with back-fed combustion of fly ash is a main trend, and the further study emphases, how to arrange the relationship of the furnace structure, secondary air and separator in reason, is pointed out.
