gas boiler design exhaust temperature


Safety valve - Wikipedia

A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would

Open Cycle Gas Turbine - an overview | ScienceDirect Topics

If additional steam is required, the exhaust gas can be used as preheated combustion air for firing additional fuel in the waste-heat boiler; thus an additional 13 000 kg/h steam at 1.75 MPa could comfortably be raised, increasing the overall thermal efficiency to more than 70% – and the supplementary fuel could be heavy oil.

Condensing boiler - Wikipedia

Since the final exhaust from a condensing boiler has a lower temperature than the exhaust from an atmospheric boiler 38 °C (100 °F) vs. 204 °C (400 °F) a mechanical fan is always required to expel it, with the additional benefit of allowing the use of low-temperature exhaust piping (typically PVC in domestic applications) without insulation

Fireplace - Wikipedia

Ventless fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. [clarification needed] In the United States, some states and local counties have laws restricting these types of fireplaces.They must be properly sized to the area to be heated. There are also air quality control issues due to the amount of moisture they release into

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

Forced-air gas - Wikipedia

Gas fired forced air furnaces have a burner in the furnace fuelled by natural gas.A blower forces cold air through a heat exchanger and then through duct-work that distributes the hot air through the building. Each room will have an outlet from the duct system, often mounted in the floor or low on the wall - some rooms will also have an opening into the cold air return duct. Depending on the

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018 · When fuel is burned in a boiler, it produces flue gas, similar to the exhaust from your car. This gas leaves the combustion chamber and enters the flue passages. The combustion chamber and flue passages (called the heat exchanger) are surrounded by water… the same water that is circulated throughout your home to deliver heat.
