Boilers fired with solid fuel such as coal or wood will be extremely difficult to estimate, since there is no way for the inspector to calculate the cast-iron boiler heating surface. In those cases, the inspector should request the boiler owner/user perform an accumulation test in accordance with HG-512(a), or a maximum burned fuel evaluation ...
