Troubleshooting a Gas-Fired Hot Water Boiler

Jan 15, 2021 · If there isn't a pressure-reducing valve, manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi. The natural gas or propane control valve for the burner is closed : Make sure the valve is open. The pilot is light out or malfunctioning : Relight the standing pilot.

2- A boiler having a fuel natural gas is used to boil

Mechanical Engineering questions and answers. 2- A boiler having a fuel natural gas is used to boil water at a certain pressure and a temperature of 120 °C. This process is performed by blowing hot air into the water (enters at 300 °C, 1 atm, 8 m/s) through a duct (50 mm diameter and 5 m long). The air leaves at 150 °C from the duct.

Safety controls for any fuel gas fired boiler

If natural gas and air are inside the boiler when the burner is lit, the boiler can explode. High Natural Gas Pressure: A pressure switch in the natural gas line stops the burner if the gas pressure gets too high. If the natural gas pressure control valve fails, excessive gas can flow to the burner.

Horizontal Steam Boiler with Natural Gas - Horizontal Gas

Jun 29, 2021 · Get Quotation. Natural gas fired steam boilers further recover the latent heat of water vapor in the flue gas in addition to the sensible heat of the flue gas, and the overall efficiency can be 10% higher than that of traditional pot and shell boilers, according to the low level of fuel development and heat and benchmark calculations. When the rated pressure of steam boiler is 0.7MPa, 1.0MPa

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
