Exhaust Temperature (o F) (o C) Chemical Oxidation: 1350 - 1475: 730 - 800: Annealing furnace: 1100 - 1200: 590 - 650: Fluidized-bed combustion: 1600 - 1800: 870 - 980: Natural-gas fired heating appliance with draft hood: 360: 182: Liquefied-petroleum gas-fired heating appliance with draft hood: 360: 182: Gas-fired heating appliance, no draftView More
High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water’s maximum temperature to prevent …View More
At present, gas is probably the most common fuel used in the UK. Being a gas, atomisation is not an issue, and proper mixing of gas with the appropriate amount of air is all that is required for combustion. Two types of gas burner are in use ‘Low pressure’ and ‘High pressure’. Low pressure burnerView More
and on the heating surface of the Exhaust Gas Boilers. The reasonable optimal steam production of Exhaust Gas Boilerswhere no economizers are incorporated are consequently reached at a steam pressure of 3-4 bar (saturated temperature 143-151°C). In practice it is found that the pinch temperature shall be kept at minimum 25°C as a lowerView More
- The gas temperature outlet in an exhaust gas heat exchanger is kept above 180°C to prevent low temperature corrosion occurring. There is about 10% water vapour in exhaust gas and also sulphur products and this can lead to suphuric acid forming which has a dew point of 140°C.View More

Exhaust gas is by-product of combustion and is naturally at a high temperature. But there is a limit to the diesel engine exhaust gas temperature, and it should not exceed the manufacturer's stated values. Learn what problems can cause this rise in exhaust gas temperature in order to enable troubleshooting and so that taking care of these factors results in restoring normal temperatures.View More
Mar 22, 2018 · If the exhaust temperature of steam is high so there could be several problems 1. If it is a condensing type of turbine then because of high temperature steam will not condense properly and it would be a liquid vapour phase at the inlet of condensView More
When stack temperature is evaluated, it is important to determine if the value is proven. For example, if a boiler runs on natural gas with a stack temperature of 350°F, the maximum theoretical efficiency of the unit is 83.5%. For the boiler to operate at 84% efficiency, the stack temperature must be less than 350°F.View More
the temperature difference between the flue gas leaving a boiler and the ambient supply temperature is 300 oC, and the carbon dioxide measured in the flue gas is 10% - then, from the diagram above the flue gas loss can be estimated to approximately 16%.View More
heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost. This is not an opinion; it is basic heat exchanger physics. The 4-pass designView More
The high temperature flue gas generated by waste material or waste liquid flows into the furnace, working medium inside the boiler will take it into the front and end smoke chamber in order, then high temperature flue gas becomes low temperature flue gas, and then discharged into the atmosphere through chimney.View More
Aug 13, 2018 · A high efficiency, gas-fired condensing boiler is one of the most economical and clean ways to heat your home, reduce your monthly heating bills, and lessen environmental impact. In most circumstances, a condensing boiler can be used to replace an existing boiler in an older heating system.View More
Oct 10, 2017 · There are no high efficiencies or savings when the unit isn’t condensing. Conversely, as the level of oxygen decreases the exhaust gas dew point temperature increases, driving the required return water temperature higher. The boiler will operate in condensing mode, at …View More
To protect the boiler itself and the flue gas system from this acidic steam, older boilers direct the flue gases outside. Depending on the heating technology, the exhaust gas temperature can be up to 200 degrees Celsius. Condensation of the water vapour in the exhaust gases is thus deliberately prevented. The recovery of the hidden heatView More
