Most boilers have multiple burners in parallel flow paths on the front and/or rear furnace walls. Burners must be similar in design and must be adjusted in the same way to optimize air flow distribution. Adjustments can typically vary the turbulence and flow rates in burners. Increased turbulence increases the air-fuel mixing.

Feb 26, 2018 · Flow switch is required for water tube boilers, fired coil boilers, pool heaters and some electric boilers: Consideration should be made to match the flow rate and piping size to the type of flow switch. Must be installed on the primary boiler loop in primary/secondary piping.
Blowdown control Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system.

Figures 12-3 and 12-4 illustrate the process of boiler circulation. The left legs of the U-tubes represent downcomers and are filled with relatively cool water. The right legs represent generating tubes and are heated. The heat generates steam bubbles, and convection currents create circulation.
