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.

Forced draft fan vs induced draft fan?
In a balanced draft boiler, you actually have both: forced draft (FD) fans supplying air to the furnace, and induced draft (ID) fans removing flue gas. Typically, the FD fans control airflow, while ID Fans control furnace pressure to slightly below atmospheric pressure. In general though, the choice between forced draft and induced draft is based on how "tight" the system is - if you have leaks, it is better to use ID, as FD will cause product loss.
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 controls an oil furnace draft?
An oil furnace draft is primarily controlled by the flue damper and the chimney design. The flue damper regulates the airflow by opening or closing based on the furnace's operational needs, while the chimney height and design create the necessary draft to exhaust combustion gases effectively. Additionally, the pressure inside the furnace and outside atmospheric conditions can also influence the draft. Proper draft is essential for efficient combustion and to prevent the buildup of harmful gases.

What is temperature instrument is used to control a furnace?
A thermostat is commonly used to control a furnace. It measures the temperature in the room and signals the furnace to turn on or off to maintain a set temperature.
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.
