I have a Trianco coal fired boiler which works well most of time. However in very strong, prolonged winds ie force 6 or above it has overheated the complete system to boiling point. On shutting it down, including the fan, it continues to burn fiercely. The only way to stop it is to declinker to remove any embers.
