Gas Hearth Pyrotechnic Dosing for Realistic Flames With Less Gas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative gas hearths require a high gas supply to create a realistic fire impression, leading to significant heat and energy loss, as the primary goal is to simulate a fire rather than produce heat, necessitating minimal fuel consumption.
Innovation Solution
Incorporating metering means with a reservoir and pump system to introduce pyrotechnical additives, such as granular materials, into the flames, which produce additional fire effects like sparks, enhancing the realism of the fire simulation while minimizing gas consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a high gas supply is used to create a realistic fire impression, then the fire simulation quality is improved, but the gas consumption and energy loss increase
Solution Approach 1:
The patent introduces pyrotechnical additives that fundamentally change the combustion parameters of the gas flame. These additives modify the chemical composition and burning characteristics of the flame, enabling enhanced visual effects (sparks, glitter, color variations) without increasing gas consumption. The additives transform the flame's physical and chemical properties to achieve better fire simulation quality with minimal fuel input.
Solution Approach 2:
The patent uses composite pyrotechnical compositions consisting of multiple components (metal powders, oxidizers, binders) that are introduced into the gas flame. These composite materials create complex combustion reactions that produce realistic fire effects including sparks, embers, and color variations, thereby improving fire simulation quality while maintaining low gas consumption levels.
2Illumination intensity
If pyrotechnical additives are introduced into the flames, then additional fire effects and realism are produced, but the device complexity increases
Solution Approach 1:
The system incorporates automatic metering means that self-regulate the introduction of pyrotechnical additives based on operational parameters. The control system automatically adjusts additive dosing without requiring manual intervention, and the metering mechanism is designed to self-clean and prevent blockages, reducing the need for complex maintenance systems and operator involvement.
Solution Approach 2:
The patent replaces complex mechanical metering mechanisms with electronically controlled dosing systems. Sensors and control units monitor flame characteristics and automatically adjust additive introduction, substituting intricate mechanical linkages with simpler electronic control systems that reduce overall device complexity while maintaining precise metering capability.
