For there is no gas resource in remote mountain areas,a 500 m3 lime shaft furnace using coke as fuel is developed to solve the fuel problem.

This paper introduces the features of lime's activity, simulates the lime kiln of shaft furnace by using 2D mathematical model, discusses on the simulation results, and indicates that the unreasonable blast-cap structure is the main reason of causing the low activity of the lime.

Numerical simulation of the processes in lime furnace;

Numerical analysis of thermal parameters and optimization of lime furnace;

Study on optimization of thermal engineering and energy conservation in lime furnace;

Practices of prolonging running period of lime kiln;

The paper studies the maintenance process of the leakage at the cover on the lime kiln of Φ5×34?m,concludes that replacing the whole cover is better than repairing it and recommends the process in detail by witch better result is achieved.

To solve the technical problems in using dry method to collect and convey the particles from lime kiln electric precipitator,the process of wet method collecting particles and fluid conveyance was adopted in Jiamusi Paper Mill.
