Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls. I am talking about big boilers
Exhaust Gas Temperature: Gas Vs. Diesel In the end, the exhaust temperature from gasoline combustion is only between 700 and 1,100 degrees Fahrenheit. Diesel. In contrast, the heavy molecular structure of diesel fuel requires more heat to trigger combustion within the engine chamber. As a result, the exhaust temperatures emitted are

Jan 06, 2014· Too hot on a probe thermometer is above 900F. Don't panic if you get a spike above 900F actual (probe) temp when starting up a fire. Probe thermometers react faster because they are in the hot gases. As soon as you start cutting back the air the pipe temperature should start dropping.
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 design
File Size: 296KB ed out of a boiler’s vent and transfer them to the boiler’s feed water • To be effective, a stack economizer needs to be applied to the right application, which usually involves a high-pressure steam boiler operating at or above 100 psig (338 deg. F°t) • Every 40-degree reduction in stack temperature increases fuel
Author: David Ludlow Typically, the dominant loss is associated with energy leaving the boiler with combustion gases. The temperature of exhaust gases is an indication of their energy content. Ensuring that the heat-transfer surfaces of the boiler are clean is a major point of focus for …
Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
This boiler shows relatively low excess air levels at high fire, but those levels gradually increase as firing rate decreases. As a result, combustion efficiency shows virtually no increase at low fire from high fire despite a significantly lower exhaust temperature. 2008 ACEEE Summer Study on …
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.
