How to use the table:
- Column 1: used material
- Column 2: total number of used materials of column 1 for flue gas out
- Column 3: total number of used materials of column 1 for air in
- Column 4: pressure drop from pressure drop table /component for flue gas components
- Column 5: pressure drop from pressure drop table /component for air components
Select the correct column for the selected boiler type
(168-5: 1,2, 210-6: 3,4, 210-7: 5,6, 294-8: 7,8)
- Column 6: total pressure drop flue gas: multiply column 2 *4
- Column 7: total pressure drop air: multiply column 3 *5
- Column 8: total pressure drop flue gas and air: column 6 + 7
- Finally add all together column 8
Total pressure drop must be lower than 150 Pa.
If the combined inlet/outlet system exceeds the maximum allowed pressure, this will result in a decrease of more than 5% of heat input capacity.
This is not allowed.
Components must be obtained from M&G
A list of allowed articles of M&G with corresponding OEM nrs is given on the next page
