Question regarding the furnace pressure of gas boilers
Thread Content
Dear teachers: We currently have a 25-ton gas boiler. Previously, due to the use of heavy oil for heating, a marble desulfurization dust collector was installed, which required an exhaust fan; now that desulfurization and dust removal are no longer necessary, is it still necessary to keep the exhaust fan? What is a reasonable pressure to maintain in the boiler combustion chamber?
Gas boilers have only a blower, no exhaust fan
Based on the selected burner and the relevant calculation documents for the furnace, determine whether to remove the exhaust fan； Gas boilers generally do not have an exhaust fan, as they operate under positive pressure.
