Process and Related Equipment for Burning Industrial Plant Waste

Abstract

The present invention is directed to a process for burning industrial plant waste, equipment for burning such waste, and a steam-generating boiler that uses the calorific power of the waste for generating energy without polluting the atmosphere. The present process is carried out by controlling the viscosity of the waste, thus burning same out, and the generated steam is advantageously used for the generation of energy through a generator.

1 . A process for burning industrial plant waste, the process comprising:
 concentrating molasses, bagasse or mixtures thereof, until a solid content of between approximately 30% and approximately 85% is attained;   preheating the concentrated molasses, bagasse or mixtures thereof between approximately 60° C. and approximately 100° C., until a viscosity suitable for complete burning is attained;   burning the preheated, concentrated molasses, bagasse or mixtures thereof in a flame burner, through nebulization.   
     
     
         2 . The process according to  claim 1 , wherein the molasses, bagasse or mixtures thereof are from soy, sugar cane, or other wastes that contain sugar or substances that may transformed into sugar through chemical or enzymatic hydrolysis. 
     
     
         3 . The process according to  claim 1 , wherein the solid content of the molasses, bagasse or mixtures thereof is between approximately 30% and approximately 80%. 
     
     
         4 . The process according to  claim 1 , wherein the pre-heating is carried out through direct steam injection into the molasses, bagasse or mixtures thereof through an injector. 
     
     
         5 . The process according to  claim 1 , wherein the preheating is carried out to about 100° C. 
     
     
         6 . The process according to  claim 1 , wherein the viscosity of the molasses, bagasse or mixtures thereof is between approximately 30 centistokes and approximately 80 centistokes. 
     
     
         7 . The process according to  claim 1 , wherein the burner is also adapted to burn BPF oil and gas. 
     
     
         8 . Equipment for burning industrial plant waste, the equipment comprising:
 a pressure tank for initially storing molasses, bagasse or mixtures thereof;   two intermediate tanks connected to the pressure tank for storing the molasses, bagasse or mixtures thereof at a suitable viscosity for burning;   two burners of nebulized liquid fuel connected to the two intermediate tanks for burning the molasses, bagasse or mixtures thereof;   two direct steam injecting devices for injecting steam into the molasses, bagasse or mixtures thereof being sent to the two intermediate tanks from the pressure tank;   two viscosity or temperature measuring devices for measuring the viscosity or temperature of the molasses, bagasse or mixtures thereof being sent to the two intermediate tanks from the pressure tank;   two first pumps for pumping the molasses, bagasse or mixtures thereof from the pressure tank to the two intermediate tanks through the two direct steam injecting devices and the two viscosity or temperature measuring devices;   two control valves for controlling the amount of steam injected in the molasses or bagasse by the two direct steam injecting devices based on the two viscosity or temperature measuring devices; and   two pumps for pumping the molasses, bagasse or mixtures thereof into the two burners from the two intermediate tanks.   
     
     
         9 . The equipment according to  claim 8 , wherein the two burners are adapted to burn gaseous fuel concomitantly. 
     
     
         10 . The equipment according to  claim 9 , further comprising a steam-generating boiler in which the molasses, bagasse or mixtures thereof is burned. 
     
     
         11 . The equipment according to  claim 10 , wherein the boiler is adapted to burn solid fuel including soy chips or crusts. 
     
     
         12 . The equipment according to  claim 10 , further comprising soot blowers for the boiler. 
     
     
         13 . The equipment according to  claim 10 , further comprising a system for controlling the emission of solid particles from the boiler, including soluble and insoluble material, the system including:
 a venturi washing unit;   a cyclonic separator; and   a mist separator.   
     
     
         14 . The equipment according to  claim 10 , further comprising a system for controlling the emission of solid particles from the boiler, the system including:
 a washing unit;   a cyclonic separator; and   a mist separator.
