-4-Section 2Design Calculations

SUNSRAYS'DbCalc©software is available to determine burner ratings and to specify minimum duct dimensions/profile plate designs.

Input data required:

A.Airflow (Nm3/h or scfm)

B.Minimum “air on”temperature

(ºC or ºF)C.Maximum “air off”temperature (ºC or ºF)

D.Preferred firing rate (kW or Btu per ft (305mm)section)

SUNSRAYS can help you calculating:

1.Heat input required (kW or Btu/h)

2.Burner length (mm or inches)

3.Minimum duct width &height (mm or inches)

4.Profile plate dimensions (mm or inches)

5.Burner turndown (&minimum achievable heat input)

6.Required air pressure drop across the burner

7.Burner head gas pressure for either natural gas or propane
