摘要

The exhaust gas -reducing nozzle of the boiler for the lower combustion constant is of a spatial shape and has a frontal wall with holes (3) and selections (4) and vertical vertical side walls (5) with cross -sectional sections (6),and a horizontal wall (7) connected to the frontal wall through the connecting wall (8). The lower combustion solid fuel central heating unit shall be equipped with at least a combustion chamber and a combustion chamber, Heat exchange and discharge installations for the combustion process and include a primary and secondary air supply installation and a reducing nozzle,located between the casings of the combustion chamber.
