Hello Peter and other moderators and users of this great forum. Myself and my partner have been building Rocket mass Heaters in Israel since last november. We have been building the J core so far, experimenting with different measurments and building materials. In the last two weeks we have discovered the wonder of the batch-box design and we are very interested in getting in to it and to be able to build this core in clients' houses. We have built an experimental 8" batch-box core using the P.B. Batch-box measurments and so far it appears to work quite well. The only thing we haven't done in this core is the P-channel because there are certain things we don't understand about that:
What is the distance between the back wall of the box and the P-channel vertical part? we see in the pictures that it is situated right before the entrance to the port, is it touching the back wall of the box and thus blocking some of the upper c.s.a of the port? I assume that not, but again what should be the distance there in this case?
What should be the length of the vertical channel from the ceiling of the box to the end of the P-channel?
Do you have any idea how we can add the P-channel without needing to replace it eventualy when the metal is starting to get extinguished?
Another question: What is the minimum distance between the top of the riser and the barrel? I know there are various opinions about this issue- I will be pleased to read as many.
Many thanks for all the generous help and info in this forum
best regards
Amit and Adiel
