Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combustion chambers clog when using maize as fuel due to oily combustion products, requiring fire movement or extinguishing to clear deposits, which is cumbersome and inefficient.
Innovation Solution
A combustion chamber design featuring rotating bodies that remove combustion products without extinguishing the fire, utilizing their heat-adherent surfaces to collect and gravity-aided discharge of deposits, maintaining fire intensity and chamber dimensions suitable for wood fuels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fire is moved to remove combustion product, then the combustion bed is cleared, but the device becomes bulky and operation becomes complex
Solution Approach 1:
Instead of moving the fire to remove combustion products, the invention inverts the approach by moving the combustion products away from the fire. The rotating bodies transport burnt material from the high-temperature fire area to the cooling area, eliminating the need for complex fire movement mechanisms while maintaining effective combustion bed clearing
Solution Approach 2:
The combustion chamber is segmented into distinct functional zones: a fire area for combustion and a cooling area for product removal. The rotating bodies act as transport elements that move combustion products between these zones, allowing independent optimization of each area without requiring movement of the fire itself
2Ease of operation
If the fire is moved a considerable distance, then combustion product is removed, but the chamber dimensions increase
Solution Approach 1:
The invention transitions from linear fire movement to rotational transport in a different spatial dimension. The rotating bodies move combustion products along a circular path from the fire area to the cooling area, achieving effective product removal within a compact volume without requiring long linear distances
3Power
If maize is used as fuel, then energy output increases, but combustion product clogs the combustion bed
Solution Approach 1:
The invention converts the harmful adhesive property of maize combustion products into a beneficial transport mechanism. The sticky burnt material adheres to the rotating bodies, which then carry it away from the combustion bed to the cooling area, transforming the clogging problem into an effective product removal solution
Solution Approach 2:
The rotating bodies serve as intermediary elements between the combustion bed and the cooling area. They collect combustion products at the fire area, transport them through rotation, and deposit them in the cooling zone, mediating the removal process without requiring direct intervention in the fire

AI summary
Combustion chamber (1) for heating systems (A) of the type comprising a container body (2) provided with an opening (3) for the supply of the fuel (C) and an area (4) for collecting the combustion product (R), between which there is a fire area (6) for burning the fuel (C). The fire area (6) comprises two rotating bodies (7) with opposite rotation directions, arranged side by side and defining longitudinal development axes (X, X') that are substantially parallel to each other, whose perimetric surfaces (7a) define a combustion bed (8) for the fuel (C) when facing the supply opening (3), and a cooling surface for detaching the combustion product (R) through gravity when facing the collection area (4).
