Through controlling the reacted materials in the first layer of medium-temperature transform furnace and the quick cooling among different stages , good benefit is obtained with the low investment.

Through the reform of the vacant equipment low temperature transformation furnace, making it in parallel withmedium temperature transformation furnace, it has reduced energy consumption and received obvious effect.

The CO shift reaction uses heat transfer technique by the sections of shift converter to remove heat.

By the brief description of the shift process, analyzed the characteristics of the shift process, checked and calibrated the strength of the shift converter, and puts forward suggestions on its operation safety.

This article introduces the detection process of the defects and its safety analysis in the shift converter hydrogen corrosion in continuous operation, and puts forward advices on limited operation conditions and treatment of the defects.

Reason increasing pressure drop of shifting furnace was analyzed in the totally low temperature shift process flow,multi-item of improvement measures for adding coke filter,using new type catalyst and perforated refractory ball etc.

This paper elaborate the main points of erection and characteristics of commissioning on the inverter frequency furnace′s water、hydraulic electric system.
