Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for producing coal additives result in low powder density and delayed combustion times, leading to increased unburned carbon and reduced energy efficiency due to insufficient micro-granulation and homogenization of coal.
Innovation Solution
A liquid coal additive is prepared by mixing a fermentation broth extracted from fruit residues with an emulsion of metal ions and bentonite or Gelite, which is added to coal to induce micro-granulation and homogenization, improving powder density and combustion area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional micro-granulation and homogenization methods are used, then coal can be processed, but the powder density remains low and combustion time is delayed
Solution Approach 1:
The invention changes the physical and chemical parameters of coal through fermentation broth treatment, transforming the coal's surface properties and internal structure. This enables the coal to achieve high powder density and rapid combustion without requiring extensive mechanical processing, thereby resolving the contradiction between combustion efficiency and combustion time.
Solution Approach 2:
The invention replaces conventional mechanical micro-granulation and homogenization methods with a biochemical treatment process using fermentation broth. This substitution eliminates the need for complex mechanical processing while achieving superior coal particle characteristics that enable fast and efficient combustion.
2Productivity
If conventional coal processing methods are used, then coal can be prepared, but unburned carbon increases and energy efficiency decreases
Solution Approach 1:
The fermentation broth treatment fundamentally changes the coal's physical and chemical parameters, including surface area, porosity, and reactivity. These parameter changes ensure complete combustion of coal particles, eliminating unburned carbon and maximizing energy efficiency without material loss.
3Object-affected harmful factors
If fermentation broth is used as additive, then eco-friendly treatment is achieved, but the complexity of additive preparation increases
Solution Approach 1:
The fermentation broth is prepared through natural fermentation of fruit residues by microorganisms, utilizing self-service biological processes. This eliminates the need for complex synthetic chemical processes while producing an eco-friendly additive that reduces hazardous emissions such as SOx and NOx during coal combustion.
Solution Approach 2:
The invention converts fruit residues, which would otherwise be waste material, into a valuable fermentation broth additive. This transforms a potential environmental burden into a beneficial eco-friendly coal treatment agent that reduces harmful emissions while simplifying the overall process.

AI summary
A method for manufacturing a coal additive that is added to coal as a solid fuel to microgranulate and uniformize the coal, thereby increasing the combustion area of the coal, leading to a decrease in combustion time and a reduction in unburned carbon generation. A raw material for the coal additive is prepared as a liquid phase by placing, in a container, a fermented liquid, which is an extract obtained from the incubation of fermenting bacteria (enzyme) in fruit residues, and an emulsion of metal ions and bentonite or gelrite, followed by mixing. Coal may be subjected to microgranulation and uniformization as a solid fuel by addition of the liquefied additive to the coal. The degree of coal powder is improved to increase combustion area, thereby shortening combustion time and reducing generation of unburned carbon, leading to increasing energy efficiency, which is environmentally friendly and safe and has remarkable effects.
