Anti pollution insert

An anti-pollution insert for heating pipes, chimney's or the like, comprising in combination,

• a. a sleeve member having at its upper circumference an upper outward extending round flange and at its bottom circumference a lower outward extending round flange,
• b. said sleeve member being secured within an associated heating pipe, having air apertures at its bottom portion, said upper outward extending flange mounted in airtight relationship to said heating pipe inner surface and said lower outward extending flange connected to said heating pipe inner surface at a location above said air apertures whereby said upper flange, said lower flange, said sleeve member exterior surface and said heating pipe interior surface form an annular shaped chamber,
• c. a plate means mounted to said sleeve bottom circumference and provided at its approximate center with a flame inlet opening which is in alignment with a thereunder mounted associated fuel nozzle means,
• d. said lower outward extending round flange provided with a plurality of air inlet openings so that air can enter said annular shaped chamber, and
• e. said sleeve member provided with a plurality of predetermined sized sleeve openings for conducting air from said annular chamber at evenly controlled flow radially inwards of said sleeve member thereby mixing with said associated flame and its inherent gasses and fuel particles so that a thorough combustion is obtained resulting in a smokeless heat output.
