· PDF fileThe purpose of the Cleaver-Brooks Draft Control system is to maintain a constant draft (pressure), throughout the firing range of the boiler. This is achieved by modulating the draft damper in response to the deviation between the measured draft and an operator adjusted set point. Draft Control is typically used in systems where multiple boilers share a common stack and outlet ductwork, or in a single …

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

By controlling the draft completely, we can reduce the need for combustion air and can apply the system to virtually any stack design. EXHAUSTO’s Chimney Automation System (CASV) is for installation and use with multiple and/or modulating boilers and water heaters.

Hurst Boiler’s sequenced draft controls consist of heavy carbon steel dampers, fitted at the boiler’s stack outlet and built into the exiting smoke box assembly. The damper is secured to the outlet using high temperature outboard bearings.

The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. Types of draft. Drafts are produced by the rising combustion gases in the stack, flue, or by mechanical means. For …

Draft over the fire (typically set to 0.02" to 0.03" WC over the fire) Draft in the breech (always higher than the draft over the fire, and typically around 0.04 - 0.06" WC). CO2 measurements (which tells us how complete is the heating oil combustion process) - adjusting the draft affects the rate of combustion air movement into the combustion
