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 ...
