Sep 12, 2019 · According to the actual situation of the boiler, the calculation is carried out. Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h. Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate.

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

What is a Boiler Flue and How do they Work? | Heatable

Sharing a Flue Vent. Up to two gas appliances, such as a water heater and furnace, can share a properly sized flue. If the furnace is a forced-draft model, the water heater must connect ABOVE (higher and closer to the vertical flue pipe) in an approved manner so that flue gasses go up the stack and not out the water heater draft hood.

Gas Water Heater and Furnace Chimney Flue Size Calculations

In modern boiler induced draft fan (I.D Fan) is used to release smoke by a small chimney. Working of Vertical Boiler: When fuel is placed in the furnace and burns then hot flue gas is generated. Then these hot flue gases pass through the fire tube and heat surrounding water. When water becomes heated then it converted in saturated steam.
