CHAPTER 3 COMBUSTION CALCULATION

Methane is burned with air in a PA Hilton boiler to produce hot water oof 55oC. The fuel is fed at a rate of 7 kg/hr at 25 C, the air enters the boiler at a rate of 130 kg/hr at 42.5oC, and the water enters the boiler at a flow rate of 1000 kg/hr at 10oC. The composition of the dry flue gas leaving the boiler at 700oC are found to be 0.9% O 2

Boiler Flues - Ultimate Guide with Boiler Flue Regulations

Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.

What You Need to Know About Venting a Hot Water Heater

Oct 22, 2021 · Water heater ducts may lead directly outdoors, or they may tie into a larger vent duct that also serves a gas or propane furnace or boiler in the home. This is called a common vent configuration. In many cases, the exhaust from the larger appliance heats up the common vent, improving the flow of the water heater vent.

Traditional hot water boilers operate without condensing out water vapor from the flue gas. This is critical to prevent corrosion of the boiler components. Condensing Boilers operate at a lower return water temperature than traditional boilers, which causes water vapor to condense out of the exhaust gasses.
