Method for stabilizing quality of double-hearth lime kiln
The invention belongs to the technical field of double-chamber lime kilns, and particularly relates to a method for stabilizing the quality of a double-chamber lime kiln. Comprising the following steps: (1) establishing a corresponding table of calorific value, heat consumption and yield of coal gas; (2) searching values corresponding to heat consumption and yield according to the current gas calorific value, and calculating gas flow through a first formula; (3) calculating the combustion air amount through a second formula; and (4) keeping the cooling air amount of 1kg of lime within the range of 0.6-1.0 Nm < 3 >. The coal gas amount and the combustion air amount can be adjusted through the actual heat value of the coal gas, the maximum combustion efficiency can be ensured, when the coal gas heat value of the converter fluctuates, values are taken according to the corresponding table of the coal gas heat value, the heat consumption and the yield, the coal gas amount and the combustion air amount can be kept in a high-combustion-efficiency state, and the combustion efficiency is improved. Therefore, the fluctuation of the combustion temperature of gas in the kiln is reduced, and the temperature of the channel can be stabilized in a small range, so that the kiln condition is stabilized, and the quality of lime is ensured.
本发明属于双膛石灰窑技术领域，尤其涉及一种稳定双膛石灰窑质量的方法。包括以下步骤：(1)建立煤气热值、热耗与产量的对应表；(2)根据当前煤气热值查找对应热耗、产量的数值，并通过第一公式计算煤气流量；(3)通过第二公式计算燃烧空气量；(4)1kg石灰的冷却空气量保持在0.6‑1.0Nm3范围内。本发明能够通过煤气的实际热值来调整煤气量、燃烧空气量，能够确保燃烧效率的最大化，当转炉煤气热值出现波动时，根据煤气热值、热耗与产量的对应表进行取值，使煤气量、燃烧空气量能够保持在高燃烧效率状态，从而降低窑内煤气燃烧温度的波动，因此通道温度也会稳定在一个较小的范围内，从而稳定窑况，保证石灰的质量。
