-5-Section 3Burner Mounting Arrangements

For “make-up air”or “air replacement”heating applications,SUNSRAYS'"D"series burners normally operate with 100%fresh air.

For spraybooth,dryer or process oven applications it is important that adequate fresh air is available at all times to meet the combustion requirements of the burner.(Refer to Appendix D for combustion air flow calculation details)

It is important to maintain a laminar airflow around the burner and should be located in the centre of the profile.(Any reinforcements used in the profile construction should be located on the downstream side of the profile).The profile plate should be constructed such that the width is fixed but adjustments incorporated above and below the burner (+/-2”–50mm is typical).

The burner can be mounted horizontally or vertically.

The preferred method of operation is for the burner to be located upstream of the

main

circulation fan so that the fan acts as a mixing device,eliminating any temperature stratification at the outlet of the heating unit.
