Ground or unground rice husk used as fuel for stationary or rotary silicate kilns as a substitute for fossil fuels

Abstract

A process for using Rice Husk residue as an alternative fuel to fossil fuels (such as Natural Gas and LPP oils 1 A . . . 9 A) in the combustion chamber of a stationary or rotary silicate kiln, where the waste is collected in dump trucks and unloaded into a proper silo; then passes through a dryer feeding silo where it is atomized in the kiln combustion chamber; a high-pressure, low-flow fan is then used to atomize it, along with all the necessary air, which can be used in oxy-combustion kilns; all the combustion gases are cooled by mixing with cold air and the incandescent gas from the kiln; and they are then collected and passed through a sleeve filter for proper filtration.

What is claimed is: 
     
         1 . A ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels system that utilizes rice husk as fuel and consists of storage silos and feeding systems for the dryer, the dryer itself, a grinding, classification, and atomization system characterized using rice husk as fuel. The rice husk will be stored in the appropriate silo, and when necessary, it will be ground in a grinder and then passed through fans. It will be atomized in the combustion chamber of the furnace using combined burners (oxy-gas and rice husk/O2). 
     
     
         2 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized using ground or unground rice husk as an alternative fuel for industrial furnaces. 
     
     
         3 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized in that the rice husk will be stored in an appropriate silo and transferred to the silo for dryer feeding. 
     
     
         4 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized in that the pre-drying of the rice husk occurs during the process of transferring the husk to the stock silo. 
     
     
         5 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by the discharge of rice husk from the storage silo to the drying conveyor, which carries out the final drying process through vaporized heating, removing moisture residues. It then feeds the atomizing fan, which directs the fuel to the rice husk/O2/air burner. 
     
     
         6 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by the rice husk undergoing a grinding and classification process after drying, before being atomized in the combustion chamber of the furnace. 
     
     
         7 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by a final process of burning the fuels and oxidizers that will be used in the process through the combined burners (oxy-gas and rice husk/O2). 
     
     
         8 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by the feed flow in the pipes and their final destination in the glass furnace, glazed or the like to be used. 
     
     
         9 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by atomization process in the combustion Chamber of a furnace, where combustion occurs; and when introduced into the chamber at 1,300° C., it releases heat to the environment, thus maintaining the temperature of the chamber. 
     
     
         10 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by the use of a high pressure fan and low air flow rate, and all the air required for combustion, with a secondary air is supplied by secondary low pressure fan placed into the already preheated chamber, to atomize it. 
     
     
         11 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized by the cooling of all resulting combustion gases, mixing them with cold air (ambient) and the incandescent gas from the furnace, which is collected and passed through a sleeve filter for proper filtration. 
     
     
         12 . The ground or unground rice husk used as fuel for stationary or rotary silicate furnaces as a substitute for fossil fuels, according to  claim 1 , is characterized using this process in oxy-combustion furnaces.
