What is a balanced draft and how is it controlled?
furnace equipped with FD(force draft) and ID(induced draft) fan /blower are called balanced draft system.Fd used to regulate combustion airflow while ID used to regulate furnace pressures type of furnace operate slightly below ATM pressure .
What removes the combustion gases from a balanced draft furnace?
A balanced draft has both ID and FD fans. ID Fan works by pulling the gases through the furnace hence creating the required draft. Where as FD fan pushes the gases into the furnace. Hence in a balanced draft frunace, the ID fan can said to be removing the combustion gases.
What is furnace draft control?
A valve that brings atmospheric air into the furnace exhaust to help expel the exhaust gases.
What is a furnace draft control?
A furnace draft control is a system used to regulate the flow of air and combustion gases within a furnace. It helps maintain optimal combustion efficiency by adjusting the draft pressure, ensuring that the right amount of air enters the combustion chamber while allowing exhaust gases to exit properly. This control can enhance fuel efficiency, improve heating performance, and reduce harmful emissions. Proper draft control is crucial for safe and effective furnace operation.
What is Difference between natural draft and forced draft in modern furnace technology?
natural draft depends on:ambient air conditionsconditions of the leaving gaschimney height
What is the purpose of the draft diverter on a gas furnace?
It protects the Pilot Light from being blown out

Down draft kiln?
A down draft kiln is a furnace where the flue (exit for burned gases) is the located near bottom of the fire box. This type of furnace requires a tall chimney to produce enough draft (or air flow) and typically produces even heat distribution through out the fire box.
What is the function of the inducer motor in a furnace?
The inducer motor in a furnace helps to create a draft that moves harmful gases out of the combustion chamber and safely vents them outside.
Why induced draft fan operate first instead of a forced draft fan?
The procedure for starting draft plant (fans) in a boiler is to start the ID Fan first. Remember that the purpose of the ID Fan is so that the Furnace operates at a slight vacuum. (See Related Link: FD Fan vs ID Fan.) Any casing or furnace leaks then allow air to leak in, rather than allowing air with pulverised fuel and fly ask to leak out.
What is draft control?
A valve that brings atmospheric air into the furnace exhaust to help expel the exhaust gases.
