| Objectives | This technical research project aims to evaluate and improve ventilation requirements for compartments housing hydrogen boilers. It will collect data on how standard vent sizes affect the dispersion of buoyant gas within a cupboard or compartment containing a hydrogen boiler and assess their effectiveness in case of an unexpected escape.The methodology for addressing this issue involves conducting a market review and measuring the free space area of standard vent sizes. Additionally, a test program will be implemented, involving the release of helium in compartments at various leak rates to simulate a hydrogen escape. This will help evaluate the effectiveness of different vent styles in reducing gas concentrations within the space. SGN has received a recommendation for potential vents for boiler compartments, suggesting a free area of 125 cm². However, initial market research revealed that vents with this specific free area are challenging to find readily available. As a result, Kiwa will conduct a comprehensive market review to identify relevant vents currently on the market and assess their free area. Once suitable vent styles are selected, a testing program will be initiated to evaluate their effectiveness in ventilating cupboards or compartments housing hydrogen boilers.During this testing phase, helium releases will be utilized to simulate hydrogen escapes, allowing for an assessment of the effectiveness of various vent styles in reducing gas concentrations within the compartment. Measurements of helium concentrations within the compartment and the adjacent room will be taken for different leak rates, providing insights into the performance of the identified vents from the market review. The conclusions of the test will be provided in a detailed report. Task within this work package will be:• Review of market available vents and purchase of a selection of potential options.• Measure free area of these potential vents.• Test work with different vent sizes (free area variation).• Provision of results regarding suitable products (inc. product reference numbers).• Report writing. The aim of this project is to evaluate the recommendations for ventilating cupboards housing hydrogen boilers and refine the requirements to accommodate standard vent sizes. This optimization will streamline the conversion process to hydrogen. | |
| Abstract | This project aims to assess the recommendations for ventilating boiler compartments containing hydrogen boilers. These recommendations are based on extensive experimental and computational modelling developed through various technical projects. However, the requirements are impractical as the recommended type and size of vents are not readily available. The project will strive to optimize these requirements to accommodate standard vent sizes wherever possible. Updating the venting requirements will subsequently facilitate the safe adoption of hydrogen for domestic use, particularly in properties where boilers are situated in cupboards. | |
