Control method of mixed fuel oven system for double-hearth lime kiln
The invention provides a control method of a mixed fuel oven system for a double-chamber lime kiln, which is applied to the mixed fuel oven system for the double-chamber lime kiln, and the mixed fuel oven system for the double-chamber lime kiln comprises a solid fuel conveying device, a gas-liquid fuel conveying device and a combustion device for combusting fuel, single combustion and/or mixed combustion are/is realized by introducing different types of fuels at different temperature stages, so that efficient mixing of solid fuel, gas or liquid fuel and combustion-supporting air is realized, the solid fuel can be fully combusted, flame of the combustor is shortened, combustion stability is facilitated, and the overall combustion cost is lower than that when a single fuel is used; and in the low-temperature heating stage, the gas-liquid fuel is adopted, the heating speed is high, the efficiency is high, the high temperature is kept stable when the high temperature is converted into the solid fuel, and the combustion efficiency is greatly improved.
本发明提供一种双膛石灰窑用混合燃料烘炉系统的控制方法，应用于双膛石灰窑用混合燃料烘炉系统，双膛石灰窑用混合燃料烘炉系统包括固体燃料输送装置、气液燃料输送装置以及用于燃烧燃料的燃烧装置，通过在不同温度阶段通入不同种类的燃料，实现单一燃烧和/或混合燃烧，以实现固体燃料、气体或液体燃料与助燃空气的高效混合，固体燃料可充分燃烧，同时缩短燃烧器的火焰，有利于燃烧的稳定，且整体燃烧成本较于使用单一燃料时更低；并且在低温升温阶段时采用气液燃料升温速度快，效率高，待高温转换固体燃料时高温维持稳定，大幅了提高燃烧效率。
