Comparison and Selection of Coke Oven and Stamp-charged coke oven;

Study on Influencing Factor of Thermal Strength of Coke;

Analysis on Influencing Factor of Coke Reactivity Test;

The difference in NO emission between blend combustion and split combustion of char/coal;

The characteristic of NO release for the chars and volatiles of bituminous during combustion;

The experiments on characteristics of NO reduction using pulverized coal and pyrolysis production of bituminous coal were carried out separately at different temperatures in a fixed-bed reactor,through which the NO reduction characteristics of pyrolysis gas,char,and pulverized coal were studied.

Study on improving the quality of coke by making rational use of coal resources and coal;

The production costs can be reduced,and the quality of coke can be improved by full using the local coal resources and optimizing coal blending.

Mainly presents the main quality control elements in delayed coking tower manufacturing process,such as prefabricating,constituting and welding,and presents quality control methods in practical manufacturing procedure,to guarantee the equipment quality to satisfy design and operating requirements.

Compared with the corrosion of four coking towers,the result shows that the serious corrosion of head or oil-gas pipes on coking towres is caused by high-temperature sulfur corrosion.

Metallographic test of the specimen material taken from a deformed wall of a coking tower was performed.
