Never had any real problems doing it that way.
That is what I want to hear FungusMan 
do you think would be any problem if I do 4 runs instead of 3 and I want to do it in a 55g drum so I think it will take more time for getting the right temp in the whole substrate so maybe doing 3 to 4 hours runs would be better... or not? 
any opinion would be greatly appreciated
As long as you can keep the water boiling, 1 hour runs should be fine. The longer the runs, the more chance of grains splitting and turning to mush.Also let me add that, when boiling my jars, the jars were only HALF submersed. So, I really don't know how to apply this to drums, unless you stacked the jars in the barrel, and steamed them, in which I would do 4 runs of 1.5 hours, shaking each before each steam session.
I'll take your advice!!!  Many thanks for your help!

would you add tape ( to prevent moisture entering the bags) to the filter if using filter patch bags instead of jars???

In devoloping countries, the sterilizer is ofter a makeshift, vertical drum heated by fire or gas. A heavy lid is placed on top to keep the contents contained. The boiling of water generates steam, which over many hours will sufficiently "sterilize" the substrate.
Who knows how long many hours is? Im guessing at least 5

No.
Do not tape up the filters on a filter patch bag.
No need to be blowing up fp bags and what not.

Taping over the patches on a fp bag would defeat the purpose. Who said that?

do you think you kill the endospores without pressure in just one 5 hours run???

Im not exactly sure. I wish good ole Paul would of specified how many "many hours" is. Try 4 or five hours of steam and see what happens.
I imagine it has to be hot dense steam though. Make sure to put something heavy on the lid to hold in as much pressure as possible. Make it so the steam has to force itself through the tiny cracks between the pot and the lid.

yes it will be safe. you aint going to make the lid seal tight enough to blow up the pot. just put a brick or rock on the lid to hold in a little extra steam and give it a go.

Timetable of the tyndallization with some H202 process Take out some of the water as it will be replace by the h2o2 1) Steam heating to 100 °C for 30 min Vegetative cells are destroyed but endospores survive
2) Incubate at 30°C-37°C overnight Most bacterial endospores germinate
3) Second heat treatment, 100 °C, 30 min Germinated endospores are killed.
4) Second incubation at 30°C-37 °C overnight Remaining endospores germinate
5) Third heat treatment, 100 °C, 60 min Last remaining germinated endospores are killed. When cool over night Inject the same amont of h2o2 that you had taken out for H20
6 forth heat treatment ,100 c 60 min Than the h2o2 sould be distrod then you cont with inculation. Will this work ?

and what about adding the H2O2 in the water used to soak the grains?
