| Abstract |
The purpose of the project was to define a suitable method for detecting leaks of combustion products from the case and seals of fan pressurized central heating boilers, which can result in carbon monoxide emissions. Several methods were found to have the potential to detect leaks: smoke tubes to produce smoke for flow visualization; flue gas analyser to detect the drop in oxygen concentration due to a leak of combustion products or to determine the flue gas composition; micro-manometers to determine the overpressure inside the boiler casing. Further work is required to determine appropriate test criteria and to develop suitable procedures for use by a service engineer. |
