Backflow Preventer Valves for Heating Boilers BBFP

Heating boiler backflow preventer valves (BBFP): this article describes check valves installed on the water supply to heating boilers to prevent heating system water from re-entering the building potable water supply system and its piping. Backflow preventers are installed on hot water (hydronic) or steam boilers on the boiler water feed line as required by both good plumbing practice and by

Gas Water Heater Vent Codes & Standards

Type "B", due to its temperature rating, can only be used with atmospheric gas water heaters. All venting installations must conform with local codes. In the absence of local codes, refer to "National Fuel Gas Code" NFPA 54 and "Standard for the Installation of Oil-burning Equipment" NFPA 31 (Tables 21-33 are based on NFPA 54).

Pressurised Deaerators | Spirax Sarco

Steam, produced in the boiler at 10 bar g, is to be used as the heating agent. If the 'From and At' rating of the boiler plant is 10 tonne/h, determine the flowrate of steam required to heat the deaerator. Before any calculations can be made to estimate the size of the deaerator, it is important to know the maximum likely feedwater requirement.

Water Handbook - Boiler Feedwater Deaeration | SUEZ

Vacuum deaeration has been used successfully in water distribution systems. However, pressure deaeration (with steam as the purge gas) is normally used to prepare boiler feedwater. Steam is chosen as the purge gas for several reasons: it is readily available; it heats the water and reduces the solubility of oxygen; it does not contaminate the water
