Im probabaly going to get some flack for this but, most stoves that have secondary air tube reburn have a tougher time burning compressed wood products in larger volumes, meaning at 1-3 blocks / bricks the stove runs good, hot stove top temps, clean no smoke, active secondary's. When you add more bricks >5 things start to get hairy with possible over fire conditions, even with the primary air turned off, its because the secondary air intake has no way of turning off, and is purely heat driven (vacuum forms, higher the fire box temp, more air goes through the secondary tubes) This equates to higher stove temps (possible over fire) faster burn times.
I own a Blaze King princes, this stove can easily operate on just compressed wood products, it is thermostatically controlled, meaning the air control will open and close by the thermostat at what ever out temps I desire, there is not secondary air to worry about, either I burn hot and have most smoke particles burn in the primary fire, or I burn at a smolder and let the catalytic converter burn the smoke (producing heat due to its location in the fire box) and get extreme burn times of 20 hrs.
I've burnt as a test about a ton of compressed wood, I've burnt smaller bricks 3x3x6" and the large tractor supply bricks. When I do burn compressed wood bricks I burn a whole package at a time or about 25-30lbs, sometimes its mixed with cord wood, other times it just them solely. Never had an issue, what makes my stove successful is the thermostat control with no secondary air tube reburn.
