Boiler Room Venting & Breaching | Superior Boil

Static pressure of the cool air (1) exerts pressure on the outside of the furnace or boiler, the breeching and stack. The pressure difference between the room air and heated gas (air) causes products of combustion (2) to flow (draft) through the unit and rise through the breeching and chimney.

Boiler Pressure - an overview | ScienceDirect Topi

Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm 2), the requirement of the CPU is usually avoided.Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.

To improve boiler control, working from the bottom up is important. A good base of instrumentation and end devices is required to support safe, reliable and optimal boiler operation. Focusing only on the periodic "tuning" of a boiler often results in masking field device issues that build up over time.
