The structure of the system chimneys consists of thin-walled chamotte pipes of modular height forming the flue gas stack and a casing made of lightweight concrete blocks. – e.g.. with the addition of expanded clay. The connections of the exhaust pipes are vertically offset with respect to the joints of the hollow bricks o 1/2 heights. Chimneys should be plastered over their entire height with a cement-lime plaster of thickness 2 cm. Above the roof slope, with the use of an additional support plate, chimneys can be additionally covered with clinker bricks.
The system chimneys are complemented by dimensioned blocks intended for the construction of gravity ventilation systems. Single or multi-chamber blocks are made of lightweight concrete with the thickness of walls and partitions 4 cm. No brickwork required, they are characterized by high soundproofing and fire resistance.
The chimney system presented below ensures the supply of the required amount of combustion air through an air duct integrated with the chimney system. This makes the operation of connected furnaces independent of the air supply from the room. The combustion air is led from the chimney outlet to the furnace in a flow opposite to the flue gases, which heats up. This helps to reduce heat loss and improves the efficiency of connected furnaces. The construction of external hollow bricks allows for connections on all sides. You can connect on one floor 4 hearths. The connections must be offset against each other by 30 cm, and opposite what 60 cm. A maximum of one chimney stack can be connected 10 furnaces.
