A lovely sunny warm Autumn day here so seeing’s as i have solar panels working away charging up my batteries i thought i may as well empty my charcoal drum and see the state of the nozzle .  
I think its been nearly a year since the last time i emptied my gasifier to check on the nozzle and clean out the ash and clinkers , and the other day it was feeling pretty warm around the bottom of the drum and so maybe the nozzle might finally need replacing after being installed in 2018 .  
Well i found out why the bottom of the drum was getting hot anyway take a look at my clinker volcano .

Most of the outer edge was pretty soft and broke away real easy , the closer i got towards the nozzle itself the harder the clinker became and the glassy hard stuff was not a easy job to clean off the nozzle without damaging it , well it did break off pretty easy as it happens and this is what i found below that hard clinker volcano

Now that’s not bad is it for a 28 month old nozzle , no wear at all no erosion , oxidation or anything at all .  
I have 3 smaller bits of tungsten that Bruce kindly posted to me , i think the time has come to try them in a new gasifier as this one just isn’t gonna wear out anytime soon by the looks of it .
