Low Profile Brooder With Non-Vertical Venturi
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brooders with vertical venturis have a high vertical profile, which interferes with poultry house operations and creates obstacles, while non-vertical venturis result in asymmetrical heating patterns due to unequal fuel and air mixture velocities, leading to suboptimal heating and fuel usage.
Innovation Solution
A brooder design featuring a non-vertical venturi with a strategically positioned baffle in the fuel distribution chamber to equalize fuel and air mixture velocities, ensuring uniform heating and minimizing the vertical profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a vertical venturi is used, then the fuel and air mixture is symmetrically distributed to the burner ports, but the vertical profile of the brooder increases
Solution Approach 1:
The venturi is reoriented from a vertical orientation to a horizontal orientation, changing the dimension in which the fuel mixing occurs. This allows the venturi to maintain its functional length for proper mixing while reducing the vertical profile of the brooder, thereby resolving the contradiction between symmetrical distribution and vertical height.
2Length of stationary object
If a non-vertical venturi is used, then the vertical profile is minimized, but the fuel and air mixture velocities become unequal across the venturi cross-section
Solution Approach 1:
A flow straightening element is introduced as an intermediary component within the venturi to equalize the fuel and air mixture velocities. This element acts as a mediator that corrects the velocity non-uniformity caused by the horizontal orientation, ensuring symmetrical distribution to the burner ports while maintaining the minimized vertical profile.
3Length of stationary object
If a non-vertical venturi is used, then the vertical profile is minimized, but asymmetrical heating patterns occur on the emitter
Solution Approach 1:
The flow straightening element serves as an intermediary that ensures uniform fuel and air mixture velocities reach the burner ports, which in turn produces uniform flame distribution across the emitter. This prevents asymmetrical heating patterns while maintaining the minimized vertical profile of the brooder.

Function Achieved in This Case
The brooder achieves a minimized vertical profile with uniform emitter heating, compatible with various fuels, and simplified, easy-to-clean components, maximizing the use of existing components and maintaining efficient heating performance.
Implementation Method 1
A brooder includes a venturi, also known as a mixing tube, in which the gas fuel mixes with ambient air
Implementation Method 2
At the burner ports, the fuel and air mixture is ignited. The burning fuel heats an emitter located adjacent to and above the burner ports
Implementation Method 3
The heated emitter warms the interior of the poultry house by radiant heat transfer
Implementation Method 4
The flame wicks along the inner side of the emitter where it transfers heat through conduction, radiation, and combustion byproduct transmission through convection
Implementation Method 5
The flame wicks along the inner side of the emitter where it transfers heat through conduction, radiation, and combustion byproduct transmission through convection
Implementation Method 6
A canopy is located above the emitter, which reflects heat from the emitter back downwardly toward the flock

AI summary
A low profile brooder is provided, comprising a venturi, a burner base, a burner cap, and a baffle. The burner base and the burner cap reside adjacent to each other, with the burner cap disposed above the burner base and with a distribution chamber between them. A central axis is defined. A venturi resides below the burner base and is in fluid communication with the distribution chamber at the central axis. The venturi defines a fuel flow path between its upstream and downstream ends. The fuel flow path resides at least partially at one or more of an acute angle, a perpendicular angle, and an obtuse angle to the central axis. A baffle resides in the distribution chamber between the central axis and the periphery.
