Understanding Combustion Efficiency and Combustion Equations

Understanding Combustion Efficiency Combustion efficiency is a measurement of how well the fuel being burned is being utilized in the combustion process. This is different from the efficiency number produced on the analyzer, which is reflective of the total amount of heat available from the fuel minus the losses from the gasses going up the stack.

Boiler Turndown Revisited | HPAC Engineering

The exit-gas temperature is a function of various factors, such as boiler efficiency and operating pressure, and can have a significant impact on efficiency (Table 2). Many boiler and burner manufacturers have elected to utilize flue-gas recirculation (FGR) in place of higher excess air to achieve the same level of NOx emissions.

What is a Condensing Gas Boiler? | U.S. Boiler Company

Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. Traditional boilers typically operate at higher temperatures, which means that a portion of heat is vented to the outside during the combustion process. Depending upon its age

What Are the Major Causes of Flame Rollout in Gas Boilers

Flame rollout occurs when burner flames exude from the normal combustion area of a gas boiler or furnace. Like furnaces, gas boilers incorporate a heat exchanger that accepts hot combustion gases produced by the burner, then transfers heat to the water. In proper operation, all combustion should be limited to the combustion chamber. Venting Issues In most cases, the sequence of events that

Troubleshooting a Gas-Fired Hot Water Boiler

A boiler is a bit more complex than a forced air furnace in that it has more parts, valves, and controls. However, gas-fired boilers are fairly reliable and, when problems do occur, they are usually related to the expansion tank or water circulation pump(s).

Dealing with the products of combustion: Part 1 - HPAC

Contractors who install gas-fired condensing boilers know that dealing with the products of combustion is a big challenge when installing these appliances. Flue gases exiting the appliance are laden with moisture, and liquid condensing from the combustion chamber and vent pipe is acidic and corrosive.

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived
