Sealed Boiler Inlet Chamber with Barrier-Based Air-Water Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealed air boilers face inefficiencies due to damp outdoor air entering the furnace, leading to wet combustion air, and existing solutions fail to maintain a sealed environment during boiler housing adjustments, affecting optimal operation.
Innovation Solution
A sealed air boiler air inlet chamber with a casing, separate water and air outlets, and a barrier to inhibit water flow from the inlet region to the air outlet region, allowing dry air to reach the furnace while maintaining a sealed environment during adjustments and normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed air boiler receives air from outdoors through a ventilation shaft, then the boiler remains sealed to the surrounding environment, but the incoming air contains significant water which reduces combustion efficiency
Solution Approach 1:
The inlet chamber is divided into a first region for water collection and a second region for air intake, separated by a barrier. This segmentation allows water and air to be handled separately, with water draining through the first outlet and air passing through the second outlet to the furnace.
Solution Approach 2:
The barrier acts as an intermediary element between the water inlet aperture and the air outlet. It selectively permits air to pass through while blocking water, enabling the separation function without requiring complex mechanical components.
2Object-affected harmful factors
If the boiler housing is sealed to maintain a sealed air boiler, then combustion air quality improves, but access for adjustments and commissioning becomes difficult
Solution Approach 1:
The barrier is configured to be removable or adjustable, allowing the inlet chamber to transition between a sealed state during operation and an accessible state during commissioning or maintenance. This dynamic configuration enables both sealed operation and ease of access.
Solution Approach 2:
The inlet chamber serves multiple functions: it acts as a sealed air intake during normal operation, provides access for adjustments when opened, and includes drainage functionality for water removal. This multi-functionality resolves the contradiction between sealing and accessibility.
3Reliability
If outdoor air is used for combustion, then the boiler operates as a sealed air boiler with improved safety, but the damp air leads to wet combustion conditions
Solution Approach 1:
The barrier extracts and removes water from the incoming air stream by directing it to the first outlet and drain system. This extraction of the harmful water component allows the air to maintain its sealed source while eliminating the dampness that would otherwise reduce combustion temperature.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively separates water from air, providing drier combustion air and ensuring the boiler remains sealed during adjustments and use, enhancing operational efficiency and commissioning accuracy.
Implementation Method 1
a barrier, spaced from the second outlet, demarking a first region of the casing including the first outlet and a second region of the casing including the second outlet, wherein the barrier is configured to inhibit the flow of water from the first region to the second region and to permit the flow of air from the first region to the second region
Implementation Method 2
A surface of the casing may be inclined towards the first outlet in use
