Discussion on Gasification of High Ash Melting Point Pulverized Coal Using Excess Enthalpy Combustion
The paper presents the principle and development of excess enthalpy combustion, and recommends that excess enthalpy combustion ( high temperature air combustion or flameless combustion ) was applied to correlative researches such as combustion and gasification of solid fuel-pulverized coal. Based on the characteristics and gasification difficulty of coal in China, this paper also puts forward that Normal Temperature Air Flameless Combustion developed by our research team can be apply to gasification of high ash melting points coal. The feasibility and the key difficulty of this technology are analyzed from the effect factors of gasification process. and then draw a conclusion that the technology has the characteristics of a wide range of fuel applicability, low oxygen consumption，high heat value of syngas，the more active content (CO+H2) in syngas，the more high overall process efficiency and molten ash extracted swimmingly and completely. It is likely that the pulverized coal with high ash melting point will be gasified commendably using the technology.
