Advanced Ceramic Combustion Chamber
DOWN DRAFT EXHAUST INCREASES
EFFICIENCY BY AT LEAST 15%.
AS THE EXHAUST GASES COOL THE
LOWER WATER TEMPERATURES
OF THE RETURN WATER CAUSES A
GREATER HEAT TRANSFER
TOP HORIZONTAL WATER TUBE
VESSEL ABSORBS RADIANT ENERGY
CROSS DRAFT DESIGN
BOTH PRIMARY AND SECONDARY
AIR ENTERS HERE AND IS
PREHEATED BY THE EXHAUST
AFTER ALL THE HEAT IS REMOVED
BY THE WATER
CROSS DRAFT KEEPS THE ASH IN
THE FIRE BOX NOT IN THE AIR.
EXHAUST EXITS HERE
NORMALLY BELOW 300 DEGREES
