Method for increasing production and efficiency of Maerz lime kiln

Abstract

The present invention relates to the technical field of lime kiln operation, and is a method for increasing the production efficiency of a Maerz lime kiln, which is carried out according to the following method: first, the parameter relationship between the air volume parameter, heat energy input parameter and air temperature in the program Modify the settings; secondly, set the air detection instrument from indoor to outdoor, and put the Weber instrument into the automatic state; thirdly, according to different manufacturers, limestone is blended and calcined according to a certain proportion, and a balance is found between kiln pressure and output Fourth, adjust the hydraulic system pressure of the Maerz lime kiln; fifth, increase the excess air coefficient; sixth, install a gas distributor at the inlet and outlet of the calcium carbide furnace cooler; seventh, add gas to the inlet of the gas pressurizer Install cooling fan. The invention breaks through the design capacity limitation of the Maerz lime kiln for the first time, solves the capacity bottleneck of the Maerz lime kiln, prolongs the cycle of cleaning channels, reduces the number of times of cleaning the horizontal tube cooler, and improves the output of the Maerz lime kiln. Produced huge economic benefits and improved the competitiveness of enterprises.

Description

technical field [0001] The invention relates to the technical field of lime kiln operation, and relates to a method for increasing production and efficiency of a Maerz lime kiln. Background technique [0002] The designed output of the Maerz lime kiln was increased from 600 tons / day to 660 tons / day. The original design of the gas calorific value analysis and control system was for automatic operation, but during the trial operation of the device, the automatic control could not be realized during the debugging process by foreign experts. It is manually operated and controlled, so there will be operation hysteresis, resulting in unstable operation of the device and large fluctuations in gas supply. [0003] As the output of Maerz lime kiln increases, the kiln pressure will increase accordingly. When the kiln pressure rises to 330mbar, the pressure of the combustion-supporting air will be too high, causing the fan to over-current. At the same time, the increase of kiln pressu...
