Abstract

The invention belongs to the technical field of lime kiln roasting and relates to a method for solving the problem that a sleeve lime kiln cannot active lime with low-calorific-value gas, in particular to a method for roasting lime with blast furnace gas in the sleeve lime kiln. According to the method, driving air for injection in an injector is replaced with low-calorific-value blast furnace gas, an injection effect is realized, conditions that low-calorific-value gas combustion temperature cannot meet the lime roasting requirement and driving air causes excessive combustion-supporting wind are eliminated, and the sleeve kiln is more energy-saving. Other parameters are optimized and configured, the method can effectively use the low-calorific-value blast furnace gas to roast lime in the sleeve kiln, the lime quality can be guaranteed, and the lime production cost can be reduced.

Description

technical field

[0001] The invention belongs to the technical field of lime kiln roasting, and in particular relates to a method for solving the problem that a sleeve lime kiln cannot use low calorific value gas to roast active lime, specifically a method for using blast furnace gas to roast lime in a sleeve lime kiln. Background technique

[0002] With the continuous promotion of the application of the sleeve type lime shaft kiln in the steel and chemical industry, the full negative pressure operation and simple production process of the production process have been recognized by the majority of lime production units. The calorific value of the fuel used requires converter gas or mixed gas with a calorific value of about 7740 kJ. If the calorific value is too low, qualified products cannot be produced even if the output is reduced. However, due to the continuous development of circular economy in the iron and steel industry, there are good ways to use gas with a calorific v...
