Through using the recovery technology for exhausting steam of KLAR deaerator,energy conversation technology reformation was made for boiler feed water system.

A series of technical measures such as adjustment of gas temperatures and amelioration of the quality of circulating oil were adopted,reaching the goals of reducing naphthalene content in gas after primary cooling and energy saving.

Reasons and harm of higher gas temperature at the final cooling stage are analyzed and solutions are proposed.

The effects of gasification temperature and catalyst species on Peicheng natural coke-H_2O gasification reaction were researched on the pressurized thermo-gravimetric(TG)apparatus,the coke's pore structures under different temperatures were observed by the Scanning Electron Microscopy (SEM),and the kinetics parameters were calculated.

Coal slurry gasification at high pressure was simulated with ASPEN PLUS,and the con-tents of methane in crude syngas at different gasification temperatures were obtained,providing refer-ences for indirect predication of gasification temperature in the preduction.

The results showed that,comparing with the equivalence ra- tio,the gasification temperature has a more obvious influence on the nitrogenous species concentrations.
