Method for reducing nitrogen oxide emission of sleeve lime kiln
The embodiment of the invention provides a method for reducing nitrogen oxide emission of a sleeve lime kiln, the method is used in the process of executing production based on the sleeve lime kiln, and the method comprises the following steps: S1, limiting non-combustion air from entering the sleeve lime kiln, including: reducing the overall air leakage rate in the sleeve lime kiln; the blowing air pressure of ash removal gas of the pulse blowing bag dust collector is reduced, and the blowing pulse width is increased; reducing air entering the sleeve lime kiln in the feeding process; s2, limiting the generation of nitrogen oxides in the combustion process of the fuel gas: fully mixing the fuel gas with combustion-supporting air and then inputting the mixture into the sleeve lime kiln for combustion so as to control the fuel gas to generate flameless combustion; fuel gas and combustion-supporting air are mixed according to the set air-fuel ratio; and the temperature of the fuel gas in the combustion process is controlled. According to the sleeve lime kiln, non-combustion-supporting air can be prevented from entering the sleeve lime kiln, gas is prevented from generating nitrogen oxide in the combustion process, and the purpose of reducing nitrogen oxide emission of the sleeve lime kiln is achieved.
本申请的实施例提供了一种降低套筒石灰窑氮氧化物排放的方法，所述方法用在基于所述套筒石灰窑执行生产的过程中，所述方法包括：S1，限制非助燃空气进入所述套筒石灰窑内，包括：降低套筒石灰窑内的整体漏气率；降低脉冲喷吹袋除尘器清灰气体的喷吹气压和提高喷吹脉宽；降低在上料过程中进入所述套筒石灰窑的空气；S2，限制燃气在燃烧过程中生成氮氧化物，包括：将燃气与助燃空气充分混合后输入所述套筒石灰窑内进行燃烧，以控制燃气发生无焰燃烧；按照设定的空燃比混合燃气和助燃空气；控制燃气在燃烧过程中的温度。本申请能够限制非助燃空气进入所述套筒石灰窑内以及限制燃气在燃烧过程中生成氮氧化物，实现降低套筒石灰窑氮氧化物排放的目的。
