Domestic heating boiler
Domestic heating boiler
(OP)
Hi everyone,
My company wants to sell condensing heating boilers on US market. These are oil fired heating boilers up to 70 kW made from mild and stainless steel. As they work under 3 bar (45 psi) pressure we need to stamp them by a H stamp. More less we know what to do but I have problems with calculations. Our boilers are not cylindrical only more less rectangular with waterway around. I have read the ASME Boiler and pressure vessel code section IV but it is made for "drum" boilers and vessels. And now I do not know what to do with that. Just calculate like plates under pressure and do not worry about the section IV? According European standard EN 303 I do not have to do any calculation if I use 4 or 5 mm thick mild steel.
Does anyone have this kind of experience? Could you help me to sort it out?
