Under EPCA, “the term `packaged boiler' means a boiler that is shipped complete with heating equipment, mechanical draft equipment, and automatic controls; usually shipped in one or more sections.” (42 U.S.C. 6311(11)(B)) In the August 2013 NOPD, DOE sought to clarify its statutory authority to cover commercial packaged boilers that do not include mechanical draft equipment by proposing the following definition for natural draft commercial packaged boilers: The term “natural draft
When draft is produced by natural means, a) hot air surrounding the boiler increases draft. b) fans can control the flue gas flow. c) a short stack will increase draft. d) the diameter of the stack will improve the draft. e) cooler air surrounding the boiler increases draft.

Understanding the operational design differences. Firetube boilers are available in either dryback or wetback design. They are identified by the type of reversal (turnaround) chamber, or posterior portion of the combustion chamber, through which flue gasses travel through the furnace to second-pass tubes to heat water within the boiler.
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.

All induced draft blowers incorporate some type of signaling device to alert the furnace that the induced draft blower is operating. Some use a sail switch in the exhaust air stream. Others utilize a centrifugal switch or electronic sensor built into the motor, and some use a static pressure tap in the blower housing.
The ABMA publishes “PACKAGED BOILER ENGINEERING MANUAL” which provides guidelines for stack and breeching designs, with a summary below. As shown below, the flow must be angled between each connection, with a change in diameter as the flow rate changes with additional boilers. Refer to this book for more complete details. III.

majority of the packaged firetube boilers use forced draft fans. An increasing number of the units are equipped with modulating or other control systems to match the firing rate to load demand as nearly as possible. Flame safeguard control systems are generally of the programming type and are frequently microprocessor based.
A draft inducer is a fan that’s located inside of your furnace near the heat exchanger. When your furnace begins a heating cycle, the draft inducer is one of the first devices that turns on. In fact, the draft inducer starts up 30-60 seconds before the burners are lit and continues to run throughout each heating cycle.
